Octane has absolute nothing to do with rich or lean at all.... octane is a rating for the fuels resistance to detonation or pre-detonation aka "knock" nothing to do with lean or rich

This is perfect for my 12am insomnia

Lot of fuel experts in the comments section apparently

Much respect to this lady and a matter of fact all the ladies in that chem lab.

Call me skeptical, but I never trust those enclosed boxes that allow you to turn a lever or wheel in order to feel the frictional difference. There could be anything inside the box causing you to feel the slightest resistenace. But, with that said, I still drive until I find a shell station. Good video VERY informative. Thanks Matt

Thanks Matt for the tour ! One thing not mentioned about dirty valves, dirty valves are not necessarily from just fuel, unfortunately in modern engines today the PCV (positive crank ventilation) system are routed directly into the intake systems due to emissions, so overtime the whole intake track gets loaded with oil due to blow by, so turbo chargers, intercoolers , intake manifolds etc get caked with oil that gets directed and caked onto the intake valves , and oil lowers octane and that’s no Bueno! ,this can especially happen on boosted cars , so the remedy for this is installing oil catch cans :) , I have been using Shell V power plus nitro for awhile and I hope what they claim is true about cleaning the valves , lubrication , and anti corrosion at least there trying to prove how and why there fuel is better :)

Very interesting. I’ve always known Shell has better gas, but I didn’t know that the other brands were that dirty and could produce that much carbon buildup that quickly. I’ll definitely be sticking to Shell gas. Good content for sure.

She looks like a villain from a James Bond movie.

I always refuel with all my vehicles, whether car, motorcycle, lawnmower or anything else, the highest fuel. It just gives me a good feeling for the engine.I never pay attention to the price or consumption Shell simply has a very good fuel. Tank only at Shell. Thanks 4 this video!

As a fellow Honda-Tech guy, I'm so glad you made this video! Keep up the great work!

Same, Shell loyal. Idk why, just am because I think it's high quality fuel and usually cheaper than Chevron here in the Bay Area! Fuel Rewards by Shell is a nice perk too.

Thanks Matt, never seen this much detail on gasoline! This is good stuff, I have been using Shell or Chevron high octane for years and will continue to do so. Thanks again Matt!

The big difference for me is I check my mpg every fill up by hand. Shell always gave me a few more miles per tank. I also have driven two nissan cars that would seem to run better with Shell 93 in them versus anything else. Overall the mpg was always slightly better with Shell.

I've been a petroleum technician for the last 10 years. I would say Shell and BP have some of the cleanest fuels. Obviously some of that depends on the site and their maintenance (especially if they have steel tanks instead of newer fiberglass), but for some reason Exxon premium always causes everything it comes in contact with to rust the piping under the dispenser gets the worst of it... I always try to put Shell or BP fuel in my C7 when it's convenient

Well I used to run only Shell 91 here in Canada in my subaru forester 2.5T when i had it. I worked on it alot like most subaru owners. Taking off the intake manifold several times being able to see the intake valve it was super polished no gunk/carbon even in the turbo it was super clean. I still run it in my new '17 Sierra and nothing bad to say about it. I also run it in my bike and my 87 Turbo Rx7. Great video lots of information

I retired from STCH a couple of years ago and it’s great to see the MR (stands for “Motor Research”) labs again. The dual fuel Raptor is parked outside the blend facility where they mix drums of custom lubes for race teams to be shipped around the world.

Wow, loved this video, soooooo interesting. I, like you have always bypassed other fuel stations looking for Shell. I have also always used V Power in my X3M40i hoping the Shell sales pitch was not BS. So now I am really pleased that I have always used it. Thnks Matt. Brilliant👍

I loved this video. Because of you, I've gained so much knowledge. 40 minutes felt like 15.

This was pretty cool. Thanks for taking us to the experts! Keep pushing and keep asking questions.

Brilliant ,thanks very much for the research. I'm using Shell V Power.

Very interesting..l have being using Shell premium petrol for the last 30 years in the UK..On the odd occasion when l had to fill up with an alternative brand the car felt rather rough. I should also add that a friends father, was a bio chemist for a French oil company (Total l think) he always made an effort to use Shell in his Jaguar, in his opinion it was the best fuel on the market.

Excellent video Matt. Thanks for sharing.

I to have always used Shell, love it!

With my years of experience with multiple performance vehicles. BP and Shell perform much greater than any other fuels I have used. Mobil is just under because of the detergence they add to the fuel. This is my experience not fact. Knock = Resistance to detonation. Lower octane on a high compression engine will cause it to detonate prior to the spark plug firing it off. The Spark plug fires off part of the fuel and the two explosions hitting each other is knock. The fact that higher octane resist knock you can increase your timing which gives you better performance. E85 has a high resistance to cause knock. It's usually about 101 octane.

Super interesting. Answered a lot questions I have always had. Great video.

Very informative!

Very helpful and lots of great knowledge 👍🏼

Learned a lot. Thanks for posting this .

Very informative Matt, good call.

Excellent video, straight from the source.

Brilliant video . Thank you 👍 Forza Shell

Love the content!

Excellent video guys 👌 thanks for doing this

Really cool opportunity for you. Thanks for sharing with us!

I think she didn’t fully understand your question when you asked if higher “octane” fuel was more combustible. The short answer is no. They are equally combustible. But if you add a higher calorific additive or blend then you get more power out. Octane, either RON, MON or the American combined one is not a measure of combustibility but a measure of resistance to auto ignition. When you compress the air fuel mix the heat and compression can cause the fuel to auto ignite. This is knock. A higher octane number means it is more resistant to this happening. So it means you can advance the ignition timing more without it auto igniting the whole charge. The normal flame front remains. The knock you hear is actually the pressure wave hitting the piston while it is still travelling up. If you can slow down that pressure wave (which is just ahead of the flame front) with a higher octane fuel then you can create more pressure with the earlier burn (as it completes while the piston is closer to the top).

The valves aren't subject to any fuel flow in a direct injection engine so how do the additives keep the valve stems and heads clean in an engine like this. The raptor engine has port injection also so that would keep the valves clean.

Imagine if Sarina was your Mom. You could talk about engines and gas all day long. I wish the addition of e-85 being added to our gas was mentioned. Great vid, Matt!

Awesome video, thanks for sharing this...

The intake side of the valve deposits is from burning blow by. The valve gets hot and the oil vapors get burned to the valves.

I would like to see a comparison of valves and pistons using Shell 87 and 91, as well as Shell compared directly to its main top tier competitors. That would be the only way to see who has the best ad pack. I will be conducting some independent ethanol testing on top tier fuels and share my contents on my channel, thanks for the insight.

Sarina was impressive. Shell is setting the bar higher for other brands. I for one will choose them because of featuring top-end cylinder lubrication.

Very interesting! I use Shell fuel ! Put the good stuff in

I want to know more about “winter” vs summer” gases for parts of the country that make the switch.

I filled up with ethanol free at a C&S (Campbell and Son) station. Vehicle start sputtering when. I had less than 50 miles to go in a tank. Filled up with Shell 93 to clean out my system. Runs strong and I got down to 20 miles to empty, still ran strong. I’m sticking with the Top Tier stores.

Fascinating stuff, always been a regular fuel.user but I can see how using a premium fuel is cleaner and beneficial to performance, economy and engine durability. 😎👍

Just some food for thought We run a fleet of Tacoma's at work and we fill them up with whatever gas station is available when we need gas and these trucks only see oil changes every 5 to 10k miles depending on model year(conventional oil vs full synthetic) and all these trucks run 250+ thousand miles no problem

I used to work for a petroleum construction company and my wife is now a receptionist at the same company. You would be amazed at some of the station maintenance that gets completely neglected. Filters are gross... Tank designs are pretty interesting also. Would be glad to get you any info I can on the actual delivery of fuel to your vehicle tank.

Surely some oil is getting to the top ring if it’s on the ring below it and traveling the full distance of the cylinder. I guess that’s where oil catch cans come in and PCV valves

Shell and Chevron 🔰 93 is Alpha

Did they touch on the Shell V Power Diesel at all? We have that here in the UK. Be interesting to know the effects (if any)

Back in the day I would only fill up my GTI using Chevron as I thought no other fuel would be good enough. Years later with my SQ5 I fill up with Costco gas. What learned is lots of this stuff (V Power, Techron) doesn’t matter too much. The reality is gas all comes from the same refineries. The difference in fuels is the amount and type of fuel additives being added to the fuel. On new cars these additives don’t matter as much as most new cars are direct inject. As a result none of these additives even touch the valves and carbon build up is inevitable. The reality is any Top Tier fuel meets the additive requirements needed for cars. Filling up with Costco, Shell, Chevron, 76, etc. will all yield the same long term and immediate results.

Hi Matt Excellent video and very informative. One idea could be to start a series about topics related to the oils and lubricants in engines, transmissions, differentials, etc., synthetic oils, anti freeze and coolants, refrigerants, basically what are the best fluids and lubricants to be used and what needs to be considered when topping up or changing any of the items. Also are additives good or bad and what to consider. In short allow people to be better informed to know what is best and what is not. I know Owners manuals provide the manufacturers recommendations however people are bombarded with sales pitches that contradict the manuals including your dealer and arming people with good data would be excellent.

I can attest to the difference of gases. My Acura TSX runs much smoother with Shell. If I put Costco, 7 eleven, Bp or others.. it doesn’t idle as smoothly or run as smoothly. The idle is much more constant and steady with the shell.

my biggest problem is the "winter blend" everyone does at the pumps, even shell. my car is tuned on 93, but my car is reducing timing because the fuel quality is not 93.

I really enjoyed this video.

I totally get this. I only fill up with shell. Always have done and I get laughed at for this

Good video man, a lot of information 👍

I believe the same additive package is used in their 87 octane fuel but at a lower percentage, so those of us who buy Shell 87 consistently can enjoy these same benefits as the premium additive percentage over time. I'd be curious to hear her thoughts about that.

Shell is my favorite.

That was good Matt.

My tuned ecoboost 3.5 has KR on shell and on Exxon synergy zero kr tried different shell stations still kr .

What about the Effects of ETHANOL of gasoline in our vehicles? 🤔 Thanx Matt for the in-depth look into fuel👍🇺🇸

thanks matt for sharing...informative and well presented by her....one comment below was that just go to any top tier station...NOT TRUE....my jaguar vandenplas….05 and 07 ran well on BP....but on shell lost 12% in mpg......my lexus es350 run great on shell/Costco/road ranger.....but get 23% poorer mileage on BP. same thing happened on all three of my Toyota avalons...the 3.5 is Toyotas workhorse....same motor just different body(Avalon/lexus)… I am curious as to whysome makes/models perform so differently amongst the top tier brands....any insights - info - as to why???

Very interesting video

I work in production for an oil and gas producer, if you have any questions from down hole to the time it gets to the refinery let me know. I’ve never worked for a refinery so I don’t know much about that process, but you mentioned wanting to know everything so I thought I’d offer some of what I do know.

Terrific, thanks for sharing. By the way I live very close to the Shell Research Center.

So, Shell says their fuel is better than other companies fuel... I’m shocked. Shocked I say!

I have more knowledge and information from here, thank you very much, I have been helped by this channel and it is very useful, I hope the channel continues to develop and progress.

I have a Ferrari. I called Italy factory. They said shell nitro is what they recommend for Ferrari ! I put it in my Porsche too and noticed a slight power difference ! Try it .

Both Shell and Chevron use nitrogen for better cleaning and better lubrication. All Shell grades are Top Tier certified, have nitrogen, and will offer some of the same benefits as the premium fuel; however, most modern vehicles with higher compression, direct injection, and turbocharging can certainly benefit from higher octane -- consult your owner's manual for recommendations.

I have used V-Power exclusively in my cars for about 7 years now. I’m glad to find out I’m not the only person who has come to this conclusion. There’s one thing that wasn’t covered that highly influenced my decision. All major fuel companies have proprietary additive packages that are well tested and proven, but they are not tested in heterogeneous mixtures with other fuels. Much less at different ratios of mixture. What may work great when unmixed may become less effective or even counterproductive when mixed with other additive packages. Nobody really does that research to even know. So I’d recommend you pick a major supplier and use their premium fuel exclusively. I would however advise that your first criteria in selection be availability in your area. If Shell is available the. You really can’t go wrong with it. If not just pick a quality brand and stay loyal.

Very informative. Suddenly I want to just fill up at Shell! What would have been interesting to know is, if you have deposits, and switch to Shell, will it remove it eventually?

Shells vpower 91 that get me like some good mpg vs there there regular

one note though, for sure they will say they have the best fuel available :), but i guess thats not the point. but curious about octane, engine cleaning capabilities and the additives for sure.

Pretty interesting stuff. I would have liked to hear confirmation whether the major refiners actually deliver the same product to the hyper-vendors like Costco or Safeway that tthey do to their own branded stations.. I represent an independent fuel jobber in CA and have heard that this is the case; meaning why go to Shell if they sell the same formula to others which charge cheaper prices for the same product. Living in CA obviously this is a big deal because of the ridiculously high price of fuel here caused by incessant environmental regulations and taxes.

Sunoco, shell, exxon and bp is all i used preferably sunoco then shell

What about Exxon Synergy.vs Shell V Power

I’d question that Octane bit

Legit just looked up this topic like 2 days ago. Only ever used shell

Oh my god I’ve been into a shell station that I watched spray roach spray ON THE FOUNTAIN DRINK DISPENSER NOZZLES. The owner has stations in every southeast state. The nice clean bright white stations too. Serena call me

Did you have a chance to meet @JoeKnowsBest while you were down there?

Maybe I should stop putting BJ’s gas in my M5 then 😂. Just so tempting when it’s $2.50/gal for 93.

yeah some of the parts sound like marketing bs :D and some statements just contradict each other like her saying that they burn all the fuel but at the same time saying that fuel lubricated the compression rings :D

So Toyota’s D4S is the way to go?

9:50 when she puts on the safety goggles 💀

Lord knows I'm going through 93 oct Shell gas like a keg at my fraternity. 3 Shell cards for 3 BMW 's. If we drove Tesla's I'd be a rich man. But not yet, not yet.

If you want the best gas, *simply* drive to Germany and find an Aral station with 102 Octane Ultimate.

My dad is a petroleum engineer for the past 30+ years, currently contracted to work for shell. My family also owns and operates many gas stations in the North East. He has provided services for major petroleum companies such as ExxonMobile, Chevron etc. He says shell v power is the biggest scam on the petroleum industry currently.

Gettin that gas money...

All TopTier gas is good. SHeLl vPoWEr loL

I will say, I started using Shell 93 on my 350z, and I felt a difference in how the car responded. It was not crazy but I did feel less hesitation and it almost seemed to help the engine run smoother vs the normal 93 I get at lets say Wawa or Racetrack. : /

As a dutch guy im all for shell :), vpower? you been fueling with vpower which is the most expensive, well if you can afford it why not. but interesting topic, im in for it.

Great job

That’s why short runs for engines kills them!

I prefer Aral Ultimate - best Fuel aviable in Germany with 105 octane 😎💪🏻

Shell's advertising regarding its renewable energy business has been described as a greenwash by some environmental lobbies,[152] leading to criticism from the British Advertising Standards Authority which ruled that Shell had misled the public in an advertisement when it claimed that a $10 billion oil sands project in Alberta, Canada was a "sustainable energy source".[153] Health and safety A number of incidents over the years led to criticism of Shell's health and safety record, including repeated warnings by the UK Health and Safety Executive about the poor state of the company's North Sea platforms.[154] Human rights In the beginning of 1996, several human rights groups brought cases to hold Shell accountable for alleged human rights violations in Nigeria, including summary execution, crimes against humanity, torture, inhumane treatment and arbitrary arrest and detention. In particular, Shell stood accused of collaborating in the execution of Ken Saro-Wiwa and eight other leaders of the Ogoni tribe of southern Nigeria, who were hanged in 1995 by Nigeria's then military rulers.[155] The lawsuits were brought against Royal Dutch Shell and Brian Anderson, the head of its Nigerian operation.[156] In 2009, Shell agreed to pay $15.5m in a legal settlement.[155] Shell has not accepted any liability over the allegations against it.[157] In 2009, Shell was the subject of an Amnesty International report into the deterioration of human rights as a consequence of Shell's activities in the Niger Delta. In particular, Amnesty criticised the continuation of gas flaring and Shell's slow response to oil spills.[158] In 1998, on its first public report on community and environmental issues in Nigeria, Shell promised "to end the practice of gas flaring in ten years, while pledging to establish a youth training scheme in Ogoniland".[159] In 2010, a leaked cable revealed that Shell claims to have inserted staff into all the main ministries of the Nigerian government and know "everything that was being done in those ministries", according to Shell's top executive in Nigeria. The same executive also boasted that the Nigerian government had forgotten about the extent of Shell's infiltration.[77] Documents released in 2009 (but not used in the court case) reveal that Shell regularly made payments to the Nigerian military in order to prevent protests.[160] Arctic project According to the Bureau of Ocean Energy Management report in 2015 the chances of a major spill in a deep-sea Arctic drilling is 75% before century's end.[161] Kodiak In 2010 Greenpeace activists painted "No Arctic Drilling" with spilled BP oil on the side of a ship in the Gulf of Mexico that was en route to explore for Arctic oil for Shell. At the protest, Phil Radford of Greenpeace called for "President Obama [to] ban all offshore oil drilling and call for an end to the use of oil in our cars by 2030."[143] On 16 March 2012, 52 Greenpeace activists from five different countries boarded Fennica and Nordica, multipurpose icebreakers chartered to support Shell's drilling rigs near Alaska.[162] Around the same time period, a reporter for Fortune magazine spoke with Edward Itta, an Inupiat leader and the former mayor of the North Slope Borough, who expressed that he was conflicted about Shell's plans in the Arctic, as he was very concerned that an oil spill could destroy the Inupiat peoples hunting-and-fishing culture, but his borough also received major tax revenue from oil and gas production; additionally, further revenue from energy activity was considered crucial to the future of the living standard in Itta's community.[139] In July 2012, Greenpeace activists shut down 53 Shell petrol stations in Edinburgh and London in a protest against the company's plans to drill for oil in the Arctic. Greenpeace's "Save the Arctic" campaign aims to prevent oil drilling and industrial fishing in the Arctic by declaring the uninhabited area around the North Pole a global sanctuary.[163] A review was announced after the Kulluk oil rig ran aground near Kodiak Island in December 2012.[164] In response, Shell filed lawsuits to seek injunctions from possible protests, and Benjamin Jealous of the NAACP and Radford argued that the legal action was "trampling Americans' rights."[165] According to Greenpeace, Shell lodged a request with Google to take down video footage of a Greenpeace protest action that occurred at the Shell-sponsored Formula One (F1) Belgian Grand Prix on 25 August 2013, in which "SaveTheArctic.org" banners appear at the winners' podium ceremony. In the video, the banners rise up automatically-activists controlled their appearance with the use of four radio car antennas-revealing the website URL, alongside an image that consists of half of a polar bear's head and half of the Shell logo.[166] Royal Dutch Shell then announced a "pause" in the timeline of the project in early 2013[144] and, in September 2015, the corporation announced the extension of the suspension of its drilling program in the Arctic.[167] Polar Pioneer A June 2014 interview with the corporation's new executive vice president of the Arctic indicated that Royal Dutch Shell will continue with its activity in the region.[64][145] In Seattle protests began in May 2015 in response to the news that the Port of Seattle made an agreement with Shell to berth rigs at the Port's Terminal 5 during the off-season of oil exploration in Alaskan waters. The arrival of Shell's new Arctic drilling vessel, Polar Pioneer (IMO number: 8754140), a semi-submersible offshore drilling rig, was greeted by large numbers of environmental protesters paddling kayaks in Elliott Bay.[168][169] On 6 May 2015 it was reported that during a coast guard inspection of Polar Pioneer, a piece of anti-pollution gear failed, resulting in fines and delay of the operation.[170] Oil executives from Total and Eni interviewed by the New York Times, expressed scepticism about Shell's new ambitions for offshore drilling in the Arctic, and cited economic and environmental hurdles. ConocoPhillips and Statoil suspended Arctic drilling earlier, after Shell's failed attempt in 2012.[171] Oil spills Shell was responsible for around 21,000 gallons of oil spilled near Tracy, California, in May 2016 due to a pipeline crack.[172] Shell was responsible for an 88,200-gallon oil spill in the Gulf of Mexico in May 2016.[173] Two ruptures in a Shell Oil Co. pipeline in Altamont, California - one in September 2015 and another in May 2016 - had some questioning whether the Office of the State Fire Marshal, charged with overseeing the pipeline, was doing an adequate job.[174] Paradise Papers On 5 November 2017, the Paradise Papers, a set of confidential electronic documents relating to offshore investment, revealed that Argentine Energy Minister Juan José Aranguren was revealed to have managed the offshore companies 'Shell Western Supply and Trading Limited' and 'Sol Antilles y Guianas Limited', both subsidiaries of Shell. One is the main bidder for the purchase of diesel oil by the government through the state owned CAMMESA (Compañía Administradora del Mercado Mayorista Eléctrico).[175] Nigeria corruption scandals Royal Dutch Shell and Italy's Eni will stand trial in Italy over allegations of corruption in the 2011 purchase of a big offshore oil field in Nigeria known as OPL 245. Shell and Eni reportedly paid $1.3 billion in bribes.[176] According to Barnaby Pace of campaign group Global Witness, "This trial should be a wake-up call to the oil industry. Some of the most senior executives at two of the biggest companies in the world could face prison sentences for a deal that was struck under their watch."[176] In March 2018, Royal Dutch Shell has filed a criminal complaint against Peter Robinson, a former vice president for sub-Saharan Africa. Shell said the two cases were unrelated.[177] Oman 1954 War In 1937, Iraq Petroleum Company (IPC), 23.75 percent owned by Royal Dutch Shell,[178] signed an oil concession agreement with the Sultan of Muscat. In 1952, IPC offered financial support to raise an armed force that would assist the Sultan in occupying the interior region of Oman, an area that geologists believed to be rich in oil. This led to the 1954 outbreak of Jebel Akhdar War in Oman that lasted for more than 5 years.[179] Climate case On 5 April 2019, Friends of the Earth Netherlands (Milieudefensie) together with six NGOs and more than 17,000 citizens, sued Shell, accusing the company of harming the climate, while knowing about global warming since 1986.[180][181]

I want to watch them cut an engine in half. I want to know what tool they used too 😂

Is that Christian making a guest appearance?? 😆

As a chemist she is accurate. But at explaining engine function and importance of fuels and oils and other engine components not to factual.....

Wow she only knows about half the facts on injection acknowledges. Port and direct injection covers the entire rpm range of an engine. They help boosted engine the most perform to there peak power.
