  • Not only has my sticture issue been completely resolved but I am amazed at how much smoother the engine is at the ...
I have a 2006 Ford 6.0L Power Stroke with approximately 133,000 miles, a couple weeks ago my engine began misfiring and had no power until the engine warmed up. It wasn't difficult to realize that my injectors were sticking (sticture). I had heard of RevX and decided to try it (new injectors are very expensive!). I was due for an oil change, so I added the RevX after putting fresh oil in the engine. Before putting the new oil filter in, I removed the tower that the filter slides down onto and then pour the RevX directly into the opening below the tower. I then drove my truck and within 200-300 yards the engine became extremely smooth and immediately had a dramatic improvement in throttle response. Not only has my sticture issue been completely resolved but I am amazed at how much smoother the engine is at the entire RPM. I can not begin to tell you how incredible RevX is! If you have a 6.0L power stroke, do your self a favor and buy this product. Even if you're injectors aren't sticking, the improvement in performance will be more than worth the price! ... show more

  • So I started to have misses in three cylinders was running like a Mack truck with a loop
So I have a 6.0 sd that I have took apart an put bigger injector tips in an lots of other stuff I knew when I took the injectors out I was going to have a problem in the future with the one side of the motor because I put all the ones I figured I would have a problem with on one side. So I started to have misses in three cylinders was running like a Mack truck with a loop. So I put Rev X 8oz in with new oil an not longer then 5min and a trip around the block it's running like nothing's wrong an it idles quieter... I should have took a video b4 an after. I would say try this b4 taking your injectors out. ... show more

  • Bye bye Stiction!
My 6.0 diesel was starting to run like crap when cold. After searching for a reason I came across a term for the problem, Stiction! If you don’t know what it is, look it up! The point is, my truck runs like a champ once again after using this kit as instructed!

  • A product that actually works
My 6.0 had a severe stickion problem, used as directed and problem solved. also added a bottle of the fuel conditioner. nice finding out about the shear effect on oil from the extremely high oil injector pressure, this all made sense. the couple of thousandths of varnish on the small pin is what causes all the sticking problem. for whatever reason chemistry wise, this oil additive corrects the problem. ... show more

  • This stuff is awesome

  • Worth every penny
Little skeptical at first, My 6.0 was really ill ( probably the Kalifornia fuel) After changing the oil and adding the oil treatment (both bottles )It took about 200 miles before it started to show any signs of improvement. On the next full tank i added the fuel additive (both bottles ) - 200 more miles and this truck had new life- never ran so good. Don't know whats in this stuff but the diesel fuel suppliers should get a clue . DERRR. Yes its expensive to try but it beats going to the stealer for diagnosis. Well worth every penny. ... show more
