Gotta say, BG has never given me a dime, but I'm a huge fan of their products. Saved my 500SL and many other older cars I've had from expensive fuel injection system repairs thanks to their 44k injector cleaner.

Project Farm needs to test this stuff.

I always love the fact that you can tell that the car wizard is a car mechanic first and that KZfaqr second. He stumbles on his words and stuff doesn't seem scripted. Stay you car wizard 😁

I'd like to see the results on the intake back of the valves with a bore-scope down the intake manifold, before and after treatment.

I actually clean direct injected car vales by taking the intake manifold off and walnut blasting them with a sand blaster at 120 psi with a valve cleaning tool similar to the bmw one. I can assure you after doing many of these. That once they are dirty no liquid flowing over them will do anything to the carbon at all.

Some people are posting here and saying that this is like a commercial. This product is a tool. If Wizard made a video about Milwaukee power tools, would that be a commercial too? BG is an excellent product and even OEMs recommend it. I don't have an issue with this video. Thank you for doing the video.

I serviced my truck two weeks ago. It is a 2005 Nissan Diesel 3 litre 4cyl engine. I changed gearbox, rear lsd diff, front diff and transfer case oils. Air filter, fuel filter and oil filter was also changed. It runs great! Greetings from Trinidad and Tobago.

Used 44K for years! Glad you showed the professional service.

Wizzard, as a mechanic, I'm surprised you let her purchase that car. 😁

I did this exact service on my 99 V6 Accord with the help of my own car wizard after doing some valve cover gaskets and noticing how full of carbon the intake manifold was. Worked like a dream, and I get all kinds of BG products from him that keep my car running great! Don't forget to check your cans for the rebate chips!

I did this on my HHR SS 2.0L turbo. It WORKS. Makes a huge difference that you can feel.

I love long Wizard videos! I look forward to them! I learn so much from you man!

I know about a very efficient method of mechanical cleaning for GDI vehicles. It involves fine ground walnut shells and compressed air. The nutshell grind is produced in California, so I guess it may even be an American product (although I know it only from shops here in Germany that use it). Edi: I googled the process, it's apparently called "walnut blasting".

Another idea is to deal with the problem at its source. It’s the crank ventilation and exhaust gas recirculation that is causing the carbon deposits. A catch can would be helpful, but it really isn’t good enough that manufacturers have not provided a solution other than to pull down the intake and media blast the deposits. I would also recommend changing the oil after running the additive because all that dissolved carbon has now gone into the combustion chamber.

I can attest that BG 44K is the best fuel injector cleaner on the market. Bought a 2001 Chevy Blazer ZR2 from Iowa knowing it had a misfire on cylinder 4. Threw some of that in the tank and it cleared it out. Super impressive product

I love BG products, use the fuel system treatments in petrol and diesel vehicles. Really helps with rubbish modern fuels of both types. I remember years ago when I was still in the motor trade and GDI was a newish thing, we had particular issues with Mitsubishi/Volvo 1.8 engines and Alfa Romeo 2.0 JTS motors losing power and running badly as low as 10k miles. At the time alot of cylinder heads and intake systems were getting replaced needlessly.

BG is back! I remember when Pat Goss was sponsored by them. Used their fuel treatment for a while.

This was more of an infomercial than a DIY since they don't sell to the public, but on the other hand it gave me the idea of using Seafoam or something similar to do my cleaning on the DI Mazda CX-7.

I had this done on my GTI last year. Made a big difference. I'm at 82k miles now and have not had to have a manual cleaning done. Although I do drive with a heavy foot which helps.

"Certain brands" = VW

Thank you wheeeeeezard. A before/after would have been a nice bonus

Some use catch cans in the pcv line to catch the oil residue before it goes into the intake. The newest oils are now made with gdi in mind so will foam less and keep the oil vapours down. Besides cleaning the fuel system, the additive in the tank never hits the back of the valve.

I had this BG fuel service done on my 2016 renegade with the 1.4L multi air turbo engine... I had it done at 75k miles...WOW!! What a difference. I’m now going to have this done every 30-40k miles.. my Jeep was getting slow and sluggish... accelerating up hills the engine would lightly ping. Not any more... this stuff is awesome. It did cost me $205.00 at my dealer to have the service done. Well worth it!!!!!!!!!!!!!! Highly recommend!!!!

I moved here from England in 1977 so l had always worked on cars from across the pond.l have two shops and BG 44k is one of the best products l have ever found.l remember using it first on Datsun cars.It completely cleaned out two carbs just by adding it to the tank.l was stunned and they Continued to run perfectly.Love all your info car wizard and you have those classic movie star looks.l just hope wizard doesn’t mean you will disappear in a cloud of smoke one day.Love your tool section .Every time l see something l think why have l been doing it wrong for the last 53 years.God Bless

It would be interesting to see a before & after video, where you show the inlet tracts before treatment & after treatment. I also dont understand how the fuel additive helps clean the inlet manifold in a direct injection engine, since the fuel dosnt go into the inlet manifold.

Thanks for this one, Wizard! I hadn't requested a video on this topic but lately been looking for a good one. Your magic is strong and ways are mighty. Cheers

370k miles on my 4.3 voretec Chevy and 270 on 5.3 ,310k on 6.0 GM service trucks vans never touched except fuel pump and belts minor stuff .Run good . This BG is good and works

Always useful info from The Wizard, thanks man

Thought that tall guy was Hoovie with a mustache.

One of the reasons why i love my IS350. It had direct and port injection

BG Products are amazing 👌 😍 it's all that touches my car. 2005 Ford focus still running like brand new after all these years. Still gets over 30 mpg like when it was new and when you floor it it gets it still. My 13 focus st gdi turbo also ran amazingly with this service.

The BG treatment tutorial is great! thanks!

I am a service tech, and have personally used this kit on my car i did borescope it before and after, mine was not coked up like the photo he showed but it did do a good job and cleaning the deposits on the valves. but still for extremly coked up ones pulling the intake and using a walnut blaster is the way to go

I used to do this on carbureted cars with Sea Foam and a couple beers. The beer was for me.

Thanks for the video Wizard. We have a 2009 Mini Cooper and wondered how the garages do that. Great information.

Love the content Iv been wanting to do this on my 06 hemi and thanks for the info I’ll be giving this a try

If I had a car I would want the Car Wizard to be my service tech!

Would have been interested in seeing piston, valve borescope images of before and after like on other KZfaq cleaner test sites.

Thank you. I had this done to my vehicle today. It rides great. My mechanic said to do this once a year as well, since my car is a Toyota with a 2.4 AZ engine and it burns oil.

BG products are excellent. I’ve used their MOA engine oil additive and it helps keep engines like new inside. Great company! Thanks Wizard!

BG just did this on my girls 16' ST Fiesta along with a performance oil change and the performance was night and day difference once I got it back. The car had 60k miles and hadn't had the induction done before. I love their products. The before and after pictures were pretty cool to see as well.

At BMW dealers we use walnut blasters to decarbon inlet ports, amazing what difference it makes

I used to do this same process with my dad for a Canadian company. It brought many cars back to life. Also good on diesel trucks.

We use to do something similar with a large hopper and ground up walnut shells for jet engines. Ha!! Dumped them right into the intake cleaned the engine out really well.

Thank you Wizard. I have a lot of Audi customers that would love to save that $1000+ bill to remove their intakes. I have used BG for years with great results but did not know they had a way to clean DI vehicles.

Is there borescope pictures before/after. We used to do this with water/ methanol and the spray into the carburetor. I didn’t have a scope then, I do now.

This is very helpful! It’s interesting to see which products the Wizard thinks is worthy. Btw, the beard is rockin’ 😃👍

If you're driving 15-20K a year then an annual de-carbon service is cheap insurance against a potential +$1K manifold service 5 years down the road, not to mention the potential fuel and power savings in the meantime. Paid advertiesment or not, this is the new reality of service, and David is simply showing some good preventative maintenance procedures. Keep them coming Car Wizard!

Thanks for the video, Wizard. For carbon control, I do like the Italian Tune Up. A little WOT keeps the mechanic away, lol. To your question, my last service was at 90K miles, and I just did my own oil change at 95K miles. My mechanic, like you, recommends oil changes every 5K miles.

I got mine walnut cleaned. Results were amazing.

Good Vlog Wizard. Thanks.

Back i the 80 for valve carbon buildup we pulled the hose off pcv valve and used water slowly at 2000rpm worked great.

Very disappointed. This was nothing but a big sponsored commercial. To have any credibility, Car Wizard should have used a boroscope video of the affected area to give us a before and after look at the actual results.

Wizard, how do you feel about adding oil catch cans to direct injection engines?

BG products have always been great. We used them at a Buick and olds dealership in Connecticut.

Thanks, Car Wizard. I might try this on my Ford Focus ST.

im just gonna watch project farms video so really see if its good

The BG kit is fucking awesome. I used it on some Audi's and BMWs, worked great.

Bg makes a great product. Alot of people don't believe that this kind of service is needed or it's a scam then they wonder why their car isn't running well and you explain that the excessive carbon buildup needs to be fixed to solve it and they still don't believe you. This is a great video. And bg are the guys dealers use it shops use it etc

I had carbon cleaning done here in Australia to my Lexus IS250 (which is GDI) and it made a massive difference. Great video.

I was worried when I saw the "Includes paid promotion" thingy in the corner of the video. But if it's something you use, I wouldn't even care if they gave you a year supply of their product. In fact, I'd be glad.

The reason for the buildup is the egr and pcv gasses . Fitting a good catch can with baffling and air oil separation will help eliminate the carbon buildup . Fitting an egr cooler will also help but few egr systems are designed properly they are designed as cheap as possible usually as a bandaid with the lowest cost assembly this is especially bad for Diesel engines. If they were designed properly the exhaust gas would be taken from after the particulate filter and cooled before entering the intake manifold.

Good video with an amazing servis🔥

Great info Wiz. I didn’t know. Now I do! That’s what it’s all about bro! Thank you. And btw my 2019 ZR1 has duel injection ports. Just sayin’...

A before and after shot of the intake ports would've been nice, but I already know this product doesn't make enough of a difference for it to be visible. Walnut blasting is the only real way to get rid of all the carbon. On a brand new car doing this service every oil change could help prevent the deposits, but at 50k miles I bet the valves are already too gummed up for this cleaner to make a significant difference.

Really cool video. I know it would be time consuming but with this particular car it would have been cool to see the before and after. Yes I know there was a before and after pictures. I know the BG representative said to do it around every 15k. But when it comes to carbon build up on a GDI engine, how many miles and or years will a GDI develop carbon?

I used distilled water injection in the vacuum line to clean up the combustion chamber and pistons. Better to rev high and to have bigger drops of water than small.

Have only heard praise for BG products. Going to have to make this part of maintenance schedule.

shouldve done something like chrisfix, and independently test it. I've used BG 44k before, not a bad product but I'd rather see a boroscope or actual before and after.

0:35 We've got Mrs. Wizards hood open. 😧🤣🤣 Sorry couldn't help it.

Great video, thank you very much.

Good video, very informative.

Surely oil changes depend on the use of the vehicle, rather than mileage? I used to drive 120 miles a day to and from work, so all condensation in the oil was boiled off. And from the exhaust system too. Short journeys in stop start traffic is what ruins oil, meaning earlier changes and rotted out mild steel exhaust systems.

I consider this video a sponsored public service announcement. Many people have no clue they have an engine that will require this type of cleaning. I don't know the benefits of one particular product over another, but intake cleaning is something that needs to be done to direct-injected engines. I'm sure The Wizard got this service for the promotion, but it was not heavy-handed; just informative.

Nice!! So it's a preventive service not a corrective service. PCV vapour reduction is also good for GDI engines with some manufacturers are actually incorporating baffling in the valve/cam covers to reduce crankcase vapours entering the induction system. External catch can a great choice as well. Nice product.

ive done this exact service on one of my cars and man did it help

Fair warning, DO NOT use this if your engine is really gunked up, you could possibly end up plugging your catalytic converter

My VW mechanic in Orange County, CA let me buy my own new Bosch injectors ($42/ea vs $156/ea at dealer) and walnut blasted my intake for $300. I went from 16 mpg at 165K to 40 mpg on hywy. I would always go walnut blast on a direct injection engine for carbon buildup.

Thank you brother!

Any thoughts/comments on the fact that as far as I know, no manufacturer that makes a GDI engine recommends this kind of service and a few specifically released statements against them? Ford comes to mind as having released an official statement specifically mentioning BG's induction service WILL damage either the engine or the turbos on EcoBoost engines (I found it interesting that it didn't even go with "may" or "might" but "will" cause damage). BG used to have a video up of them using their induction service on a 3.5L EcoBoost and has since been taken down off their site, the rumor is that they were forced to take it down. Interestingly it seems like Ford dealers still try to sell this service so Ford released an official letter to their dealers telling them to knock off pushing unnecessary and potentially harmful services on their customers, I believe that this one specifically mentioned BG's induction and fuel injection cleaning.

There comes a time when after you've reengineered the injection systems of every modern engine that you really need to reevaluate the EGR system as well. Get rid of intake vapor and you'll fix the issue with all the carbon on the valves.

lol. I’ve come from the future. You’ve really come a long way in 4 years (and lost a bit of hair) Great info.

As usual a great educational video. Are there any precautions to be consider with the O2 sensors. The old school guy.

What would be the cost of this service? Which cars/engines are more prone to carbon buildup?

Another common failure mode of carbon buildup on the valves is the valve not sealing perfectly any more, and sometimes even burning a hole inside the valve, so there is no compression left on this cylinder, and the engine needs new valves.

Been recommending BG since 1990’s just the additive to the fuel cleaned out an old Volvo and got it running like new in less than a tank of gas

GREAT video Car Wizard - will you do some VIDEO inspections before and after the cleaning? 😁

Are carboned up tail pipes a sign that an engine is dirty and gummed up, even after a year from new?

I've been changing all my cars at 3k or 4k Tops all my life. Might explain why I've never had any major issues with a vehicle. My first vehicle I sold to a buddy (97 dodge neon) has around 560k on the original engine and is still going strong lol. I've always been OCD with preventive maintenance

I had this service done on my 2020 Honda Ridgeline RTL-E with 75,000 miles on it. I'm not sure exactly what the Honda dealer used. But my Ridgeline seems to running smoothly and a little bit quicker reaction in the throttle

Stuff is legit, makes a huge difference and especially for $100 or so. Annual service is helpful

I was badgered by my Honda dealer to pay for a "fuel injector system service" on my Accord. I eventually caved, and afterwards asked what they found - "actually it was pretty clean". That was the first, and last time I paid for a fuel injector cleaning. I discussed why this was the case with the service assistant, and unsurprisingly we came to the conclusion that it was because, after over 200k miles, the only gas that had ever gone into the tank (with probably only around 5 exceptions) was either Exxon or BP gas. If you buy poor quality gas then you may find you pay somewhere down the road.

Would have liked to see a before and after borescope to show if it did anything.

Great video WIZARD..

very helpfull for my mustang

Before and after pictures please!! Otherwise any one can say it works.

I've used similar products before - but I always fall back on using Ethanol and water mixes to get the job done. I have similar results at a fraction of the price.

My mechanic puts carbon cleaner in my flat 6 Subaru it’s a little can from Subaru it’s not that expensive for the life on the engine. Great video very easy and informative 👍

And some companies that manufacture these cleaning products recommend an oil cleaning After cleaning the valves Can be called internal engine cleaning. That is to add a cleaning agent to the oil and gas for 15 minutes, then drain the oil and change the oil filter. There are also special oils that already contain cleaning chemicals
