REV X Distance Plus Gold Diesel Fuel Treatment for ULSD & BioDiesel (16 fl. oz. - 400 Gal.)

IT WORKS WELL, IF USED AS DIRECTED, ADDING MORE THEN RECOMMENDED DOESNT INCREASE THE RESULTS, THE DIRECTIONS ARE PRETTY MUCH SET TO GET YOU THE MAXIMUM RESULTS. i also changed my oil at the same time and used the REVX ZDDP oil additive. In my 2004 Freightliner Columbia with the Mercedes MBE 4000 , Its 120,000 miles on the second in-frame overhaul, approx. 1,690,000 miles total on the truck. I gained 1.75 MPG first fill up to second fill up, and real close to the same since adding both to my regiment , with exception of changing variables such as idle time and load differences. I recommend both.

I used this in my Ford 6.0 diesel. I drive back and forth from Texas to California towing a 10,000 pound trailer. Rev X increased my gas mileage from 10 mpg to 12 mpg. Plus, the engine runs quieter and smoother. I was definitely skeptical when I bought it. Now I will always use it on my long hauls.

I drive a 2006 Cummins and this stuff is the bomb. My engine runs noticeably better and gets better mileage. If you have a diesel this stuff is a must use.

First time using it I noticed that it made my tractor start up easyer even in very cold mornings. More power available also. For some reason it seams a little more quiet

At idle the engine seems to run slightly smoother with less clack noise. Used it in a high mileage 7.3 I’ve noticed 0 difference in fuel economy but I’m sure the injectors don’t mind fhe extra lubricity.
