ok so just arfter some input i have noticed that some fuel manafactures put arfter run oil in there fuel is this a oxymoron at all does it effect the fuel to me it seems a waste what do you guys think

I would think so....

Many of the things we use for after run oil do not mix well with methanol.

As for the ones that say they already have it in their fuel, that just means it has more synth in it. Kind of a waste.

There is a difference between afterrun oil and anti corrosion additives....

But if the fuel does contain castor oil then that will work as a kind of afterrun.

very cool...
