Yeah, it's a little bit self-regulated. On the other hand, and the lower end there's some pretty wild claims being made by small batch manufacturers which don't seem to stand up. Unfortunately they're small enough that's its not really worth anyone's time to take legal action.

They're very careful about publishing any information that identifies specific competitors, probably for fear of legal reprisals. But the majors do "take aparts" all the time - in which they identify every component of a competitor's product. Plus they do benchmarking too.

Sure thing!

Thank you very much!

Glad you liked it!

Very true!

That is where brand reputation comes in. But partly due to consumer overconfidence created by superficial laws, and partly from snakey quick turn over CEOs who don't care about long term fallout, a lot of this reputation based system has been lost while chasing ever finer penny pinching.

@@mytech6779 Marketing isn’t a new evil plan by short sighted CEOs. Technology has just made it easier to spread “the word”. As always, it’s consumer beware. Everything purchased comes down to how much time someone is willing to spend researching (any) given product. Fortunately, for marketing, it’s not munch-

@@watercooled8105 It isn't marketing, it is bait and switch, combined with clever accounting expending brand equity to temporarily give an illusion of a boost in net profit. Taking a reputable brand and suddenly switching production to inferior garbage products for a quick profit boost before buyers catch on, then abandoning the empty hull and moving on to fresh prey has been a growing trend. (Much like pulling money out of the savings account each week to pretend your weekly income has increased. Or cutting the budget for R&D knowing that the there is a 5 year lag for new product development and you plan to retire or change companies in 4 years.) It is not only a problem for customers, but also for the long term investors that are left holding the worthless remains.

@@mytech6779 None of which will happen without the product (good or bad) being sold first. It’s a very old game played with new technology. Except now the new technology can cut both ways.

Shell was planning to make a natural gas oil refining plant in America, but later decided it would be cheaper to continue making it in Qatar and exporting it to America.

Glad to be of help! I've reached out on LinkedIn, there may be some other ways I can help.

@@LubricationExplained I have connected with you...hoping to learn alot from you

There are some oils that are advertised as "100% PAO Esther" like Penrite Ten Tenths. If you really need the best just buy those.

@@thomas316 and castrol 0w range oils are group4/5 basestock.

Glad to be of help!

Glad you enjoyed it!

Thanks! Most GTL is made in Qatar but there are a couple of other smaller plants around.

No worries! Hope it helps.

Sama sama!

Thanks mate! Hope you're doing well over there.

No problem 👍

I read about that case. It's a funny instance of history repeating itself. We're currently experiencing a very similar problem in the industrial gas turbine market, where a move from Group I to Group III turbine oils is causing a tonne of varnish issues.

It might even be true to use "it's the best" meaning "best equal", but that might be pushing it!

At least the "up to..." weasel-phrasing is easy to spot. I always reword those as "less than (or equal to)...". :D

Yeah, flushing of engines it really only a thing when you let the oil go too long and have a lot of deposits.

Thanks and welcome!

Could you explain about hydraulic oils & rotary screw air compressor "SULLAIR" oils & was ATF "automatic transmission fluid" used as early day hydraulic oil?

A mate made a good point one-day saying that 2-stroke oil mixed in with petrol actually softens the firing in the cylinder as also lubricate the bearings. What is your thoughts about 2-stroke oils?

Yes - theoretically the OEMs should probably be specifying viscosities by region, but most don’t seem to be.

@@LubricationExplained yes. this seems to be the cause of engine having sludge even with more than frequent oil change. Engine flush become popular here.

Project Farm channel already done comparison test between Amsoil and Penzoil. Amsoil won. But Penzoil have better price.

The excellent video and some of Rafe's replies to other comments highlight that claiming "better" is fraught with difficulty, as an oil is addressing a matrix of requirements. There's also the issue that people confuse the performance of viscosity grade X with viscosity grade Y - or even worse - compare "Shell Helix" with "Castrol". Just go check out how many sub-brands there are, regardless of viscosity. Consumer legislation in the USA and many other western economies means that the vendors have to sell these with different formulations in that country if hey wish to charge a different price. In another example of avoiding temptation to jump to conclusions, Rafe gives an example of how easy it is to find old data for a fluid no longer sold. It's then tempting to compare it with a current product. Another issue where people seem to get confused when discussing lubricants is to compare the performance of finished fluids based on particular components. While directionally it is true that PAOs have advantages over API Group III fluids in certain properties, it's possible to 1) make a rubbish lubricant from expensive components that have excellent properties and 2) formulate to meet most specifications without using the most expensive ingredients.

There's an Ultra Platinum Racing version that is used in competition. The MOTUL 300V Racing has less than 50% ester [relatively very high] for same use. Esters or relatively high amounts of ester aren't used in passenger car engine oils for long service drain intervals bc of esters water affinity and seal corrosion.

Havoline's full synthetic has less than 10% ester/1-octadecene

Yeah a lot of the OEMs are chasing lower viscosities purely to make the cut on emissions regulations. Does it make a huge difference? Probably not but I guess if you gain 1% from the lubricant and 1% by improving the ignition patters and 1% by turbocharged etc. it all adds up to something material. It's probably driven more by the EU than the US EPA to be honest. A combination of reduced viscosities and reduced antiwear packages logically leads to more wear.

For many year now in the USA all sae40 oils and some straight weight 30 are marketed as a "heavy duty" oil and are allowed to have more anti-wear phosphorus, zinc and so on. While multigrade sae30 and lower viscosity are considered passenger car oils and must allow catalytic converters to meet a certain performance spec at 100k miles. I would be interested to know the amount of mineral build up in the exchaust side of your heads and manifold, a lot of HD oils are co-labeled for gasoline or diesel and have higher TBN, which has in some cases caused mineral deposits when combined with low sulfur fuels because there are fewer acidic sulfur byproducts for the calcium to react with.

@@LubricationExplained Doesn't the molybdenum make up enough to replace the lower traditional anti wear additives? Plus boron for the timing chain?

@@jc.1191 Mo is not long term sustainable decreasing mileage intervals

Good question. Unfortunately the answer is "it depends". Some API and ACEA specs are equivalent, so you might be okay.

@@LubricationExplained thanks you... another doubt; From ACEA A5/B5 is it Ok to go up to C2 ...

Sticking my nose in here. I´v never seen a motor oil container that did not have the API rating here in the EU. I have noticed that the ACEA rating can be missing. Bought a jug of MANNOL 5w30 on line and it only had the API and ILSAC ratings on it.

I thought they used coal...

@@KaLeB_ yes, you’re right. They used coal to make syngas and then liquid petrol. At least that’s what a professor said in university.

Good question. I haven’t personally used them so I can’t comment on performance, but they seem to have a pretty good reputation.

Hahaha. It's a shame that there are some salespeople out there that have given the profession a bad name. It will be interesting to see how sales fare in the future, the business is becoming very data-driven and less reliant on relationships.

Motul are known for 100% synthetic water engine oils.

Hahaha
