If you have a 6.0 Powerstroke that is starting hard and running rough, you may want to give Rev X oil additives a shot at fixing it. Over time the injectors on the Ford 6.0 Powerstroke diesel will build up residue on the spool valve area that causes them to stick upon cold start up. Also the extra lubrication from the Rev X makes the spool valves work better period.
We were huge skeptics on whether or not this product actually worked or not until we tried it. We got a couple bottles to try and dumped them into Pam's Excursion without telling her. Her 6.0 Excursion had relatively newer modified injectors and never had a starting issue. About two days later she came in and asked if we had done something to her truck. She said it would "jump" to life when she turned the key. We were suprised she noticed a difference since she really didnt' have an issue to start with.
So we tried Rev X on more trucks and had great results. This led us to become a dealer for the Rev X product and have been continually amazed at what a difference it makes. If you have a 6.0 Powerstroke with starting issues, try two bottles with your next oil change. After that you can just add one bottle per oil change. We have been able to save customers tons of money by not having to change their injectors to cure the hard start issues by instead just adding a couple of bottles of this great product.
It also works great on other diesel engines as well. The 7.3 Powerstroke will see performance and start benefits since it also uses engine oil to run the injectors. We also have lots of Duramax and Cummins pickup owners who use the product who tell us they see better turbo performance and increased all around power and mileage when running the Rev X products. Even our one sales guy has cured the noise that Audi engines are known to have on start up by running a bottle of Rev X in his oil. It's a great product!
