yes i am aware this is probably a dumb question but i got a 2006 f250 and i'm running rotella 15w40 oil. im wanting to start adding rev-x to my truck but im seeing everyone whos running that is using like 5w40 synthetic. do i have to run that synthetic or can i still do rev-x using my current 15w40 with no problems?

thanks

You can use the 15w40. But the synthetic is the better option.

Run it in whatever oil you choose. Still does the same thing regardless. 6.0's just love synthetic oil more than any other diesel normally does IMHO. Has to do with the way the injection system operates.

You're welcome. The only reason I know that is because I've been researching it for a couple of days now because I've never used it either but I'm with you at $65 for 8 oz of additive it better be something wonderful. From the reviews and all the testimonials I've read it is though.
