Remember if your truck doesn’t have that problem it’s not going to fix that problem. The trucks are using it and do have the problem. It works great but you won’t see any performance increase if you don’t have the problem.

I use in my semi since I got it with 247 miles in 2020 from the dealership now have 555183.7 miles . Truck still pulls like a train pulling smooth bore liquid tankers but that’s my experience. Hope it’s works for you

It does work wonders and it cleans the engine as it runs too. It is not an engine flush that is so harsh you have to get it out of there in 10 minutes but rather you can leave it in until the next change. If you get any leaks they were already there in the first place and plugged by sludge deposits that are now gone.

I have tried some of the FR3 in my Nissan Rogue. It is just a 2.0 in that one but it did make it feel more responsive. It is not a high mileage vehicle either. It has 60,000 miles and may last longer if the CVT doesn't fail. I have changed the CVT fluid so hopefully that helps. It does feel smoother after that especially if you do that little cartridge filter on the side (it is different from the one in the pan).

After my fuel filter water separator rebuild, the 7.3 ran much better. Hot S🎉hot in the fuel and crank case solved the exhaust smoke stack. It's got 540K, and never changed the injectors, but did put "O" ring kit ($15) on all of 'em.

Worked for me, 7.3 1995

I used half the bottle an it worked equal if I used the hole bottle.

So you put all of that in there? For the first dose and topped the rest off with oil?

Mine started better with it but I run 10w30 in mine . Rotate your batteries once a year from left to right an left to right.

Low oil pump?

Rev-X is exponentially better for stiction issues. This stuff is trash in comparison.
