a product called Oil guard? http://www.oilguard.com/ if so, do you like it? and do you see see good benefits from it? i have an "Stock" '04 F250 6.0 Powerstroke and would like to find any better solutions for better Diesel mileage, and want to take care of this bad boy (best so far is around 13.5 MPG) prob not bad considering the truck itself (see SIG) ..........and my led foot!burnout
I would look at switching the motor over to Amsoil Sythetic oil and using the Amsoil Bypass. I use it in my truck, my Dad's 7.3, everything. Great oil, most customers tell me they pick up anywhere from .5-2mpg. And its great for your motor. A little more affordable than most other bypass systems, also. Exhaust can help out mileage as well, but the lead foot is killing it!rotfl
i checked the link for your store, but was not sure of which Amsoil (style) you were talking about, (for Diesel).
NVM, i figured out linky, https://www.amsoil.com/scripts/runisa.dll?amsoiloaf:index thanks.... but i still want to hear form some oilguard users.......
