Vavoline VR1 20W50 Racing Oil

I have been using additives since day one and never had a problem.

I like using marvel because it really keeps the engine clean and the fuel system lubed.
It seems to keep the engine cleaner then just oil alone.
Lucas is nothing more then a very advanced stp oil treatment.
It sticks to internal engine parts and has a higher build- up film then just oil.
I have never lost a engine and they are the cleanest engines when taken apart i have ever seen.
If i had to pick one, I think marvel mystery oil is the best.

When you add it to your fuel it lubricates and cleans everything from the gas take to the piston rings.
Why do you think diesel engines last for a half a million miles or more.
Diesel fuel has a very high lubricating quality to it.
Marvel helps a gas engines rings last longer just like diesel fuel helps a diesel.
To each his own..................10 ways to skin a cat i guess.

I have seen people run their oil so long it looked liked mud and nothing bad ever happened.
I wouldn't reuse any of their engine parts over though.

I have to use my parts over and over and do everything i can to help them last for a long time.
The stuff i add seems to work really good,so why change a thing.

I have been running the same carter hi volume fuel pump for 17 years with out a rebuild.
My buddy uses marvel in his e85 road runner to help his fuel pumps.
He has not lost a fuel pump since.
