I am not an expert on the topic but, I suspect fuel choice and driving habits can influence carbon build up. I only use Tier 1 fuel.

On a previous vehicle, I'd put in a Chevron Fuel System additive once every few months. No clue it it was doing anything as I never needed to take the heads of or use a bore scope. The Engine was a 2.0 Ecoboost, twin turbo Ford. 160K, running like day one, same gag mileage and performance. Granted, that is a scientific analysis.

Kinda off topic, is anyone using a Fuel cleaner or additive on the 4R yet? I'll start a new thread if I don't see one already.
Like I previously mentioned earlier in the thread. I think some have missed it. I corresponded with J&L. All they do is catch cans. I asked why they don’t offer one for this motor. I don’t remember the specifics but they said something about the design of the crankcase and how it vents. They won’t be making one and don’t recommend putting one on.

Because you dont have experience with turbo charged vehicles?
Actually, I have, small turbo engines like the ones in the four Runner. Large high-performance engines may benefit, the manufacturer of the kits certainly benefit. There are tens of millions of small turbo engines that have put on billions of miles without benefit of these kits and seem to have suffered no ill effects.

On the other hand, I did order some large flame decals that I will put down the side of my 4Runner. The company selling the decal guaranteed an extra 20 hp.

No ill effects other than burning oil in the combustion chamber for no reason at all. Because burning oil is great for an engine. Or do you just not understand where the oil is going now?

If J&L says not to run one then i wouldn't run one they are one of the OG's in the catch can game and know there shit! I ran one on my Explorer St i had and traded for the 4runner and still run one on my Raptor.

Catch cans have there place and are application specific and not a be all end all just cause your boosted. It all depends on how the PVC system is plumbed and operates. They also work on NA motors. I have one on my 2013 Ford Raptor with the 6.2L as the way the system works is it recalculates warm gasses that carry the unburnt fumes along with oil vapours that get carried along for the ride straight back into the air intake to get recycled. But once they hit the cooler air/air intake they condense and they coat the throttle body's in the 6.2L Nothing major but if you run it hard its just cheap insurance and save from having to clean the throttlebody's as offten.. Thats why direct injection have more issues with valve train fouling due to this and need to be cleaned periodically cause they don't have the port injection that helps reduce that build up. But like i said it all depends how the system works on the specific application.

NA and low boost turbos that are DI and Port injected not really needed in most cases. High boost and DI Injected benefit the most.

And yes i drive the shit out of my Raptor.

So maybe you can explain to the crowd how so many millions of engines have survived to this point without some kind of engine saving attachment sold by snake oil salesmen.

Besides, burning oil in a very minute amount has no effect on the vast majority of the engines in cars today.
If you want to waste your money on a gimmick, feel free. While you’re at it, you might go ahead and put one of those magnets on your fuel line that helps increase fuel mileage.

No one said your engine wont survive. Burning oil 100% has an impact on every engine it occurs in. The fact you are comparing this to a magnet on a fuel line says all I need to hear.

I use a magnet on my oil filter just to save the filter some work
