rev-x really does work - my story

few months ago i did an egr delete with some extra upgrades and i switched to CAT elc, my intake was very nasty and wet and i was getting white smoke on cold starts. after the delete the truck noticeably ran better until about a month ago. the white smoke came back, and the motor was missing for a few seconds right when you started it. i took the truck to get the injectors checked and i had #4 replaced, that cured about 50% of my problem. no more missing, but i was still getting a fair amount of smoke on cold starts along with the fuel smell. checked my ficm, ipr, and hg's all were good. i decided to try rev-x, i put it in 4 days ago and now she is running like a champ. no more smoke at all, and no funny smells. this stuff is awesome, if anyone is having a similar problem, give it a shot!

from what I've been told, REVX is good for preventative maintenance but if you used it to solve your issue, you're masking the inevitable... Hope it actually fixed your problem!

Incorrect. The problem is injector stiction and Rex-X eliminates the stiction. There is no masking going on.

When I first got my truck last year I changed the oil with Rotella T 15w40, early summer.

Early fall I started having rough cold starts as the temp dropped. When the oil change came due I used Rotella T6 5w40. It helped a lot, but it didn't completely solve the problem. After a week to see what effect the synthetic oil alone would have, I added the RevX. Major difference! Completely cleaned up the rough start and smoke, for a while. Still no rough running, but the smoke came back. Now, I don't know when it happened, but my EGR cooler has started leaking at some point, so it was probably injectors before but I don't think it is any more.

Second synthetic oil change and it's even better if that's possible, and that's without any new RevX added. I did get two doses in case I needed it, but I haven't so far. I will hold onto it through next winter at least, then if it stays like this I'll sell the second dose.

Questions before putting her back together

Couple of questions:

06 6.0 Just repaired STC fitting...
When I took my intake off it was all caked with soot. Dry but still nasty. Is there anything I can use to help clean the intake manifold other than elbow grease?
I am in a very warm climate. Lowest temp usually maybeeeee freezing. What oil? I have been running 15w40. Not synthetic, will it make a difference? And should I use RevX?

Have to wait for some $$$ to take care of oil cooler (which was in great shape) and egr cooler. Don't want the headache later on!!

i don't think it's masking a problem. i had the injectors checked and only #4 was low so i replaced it, that was causing most of the smoke and the missing. rev x just freed up any sticking injectors.

i'd get the intake manifold cleaned in a parts solution at a shop, like soaked in it. i used a ton of brake clean on mine and it didn't get everything out.

What's in Rev-X? I am going to try Prolong to fix my rough cold start issue.
