i run royal purp 15w40

 

I use the ford motorcraft powerstroke 15-40 oil

 

RevX can be added with every service/oil change, but RevX can also be added to the transfer case, differentials, power steering, and manual transmissions with clutch for better performance--NOT to be added to automatic transmissions--too slippery! The exact amount depends on where you're applying it, you can find out more either here on our site (Really good diagram and application guide) or call for more specific info:

Yes, drain intervals can be increased, how much the interval is increased depends on your individual truck and how it's used. It would be great if you can do an oil analysis, but then, keep in mind that if you do one with RevX, we would help evaluate it with you, as it would show the unique properties from the Revx. To do an analysis properly, you would use the same drain interval for comparative data. This is something to ask about when we get ahold of you, and go into more detail then.

Those are really good questions! There are a lot of great uses for RevX! We are excited to especially see how it will work with your 6.0Ls and the cold start/cold run issues.

 

so sun wanted me to post the drain intervals i use and to have yall do the same so that blackcloud can have an easy way to find out any and all info they need rather than having to sift though so many pms

Yup, if you could post here with this kind of stuff, that would save me time sifting thru the pm's, but still use a pm for your phone number, etc.

 

Please include me in Rev-x test. 2003 Ford Excursion. Cold start issues. Truck has to warm up at idle for about 5 minutes then still lacking power for first few miles. Runs rough between 47 and 53 mph for about first 10 miles in the morning. Stock with exception of Air Raid.

Oil: Rotello
Oil changed every 5000 miles.
79,000 miles.

 

Well that just figures! I just purchased 2 bottles of the rev-x from their web site about a week or so ago. I posted my results up in the general diesel discussion section. To say that I am pleased with the results would be the understatement of the century. I have been around for a long time and have never seen a product work this well. Guys, it saved me thousands on having the injectors replaced with a total out of pocket cost of $75.98.

 

Il try some !!! my 04 f-550 with 310000kms on it hates cold starts it sounds like its going to blow up, but once it worms up for 10 mins its good to go. I change the oil every 10,000km iv been running 15-40 since new. but last oil change i put 10-30 and that made a little differance but still hard starting when i leave the truck cool down.

 

Hi Guys! Just an update. We've gotten ahold of about half the people and are still waiting for contact info from some of you, so please check your inbox! We've got RevX shipping out for some of you to test already today!

I'm looking forward to hear how it works for your cold start problems, and any other applications you try!!


and... HAPPY FRIDAY!!
