Shumi! Thanks for the invite.

Actually, recycled engine oil isn't as bad as one would think. It uses all sorts of oil - ATF, Tranny oil, gear oil prtty much anything that is put into the waste oil drum.

That waste oil is "spent" which means some of the additives have been depleted while contamination in the form of dissolved metals, water, fuel and dirt, soot, and sludge are present. The refining process is nothing more than a glorified still. The oil is boiled up normally with crude and fractioned off. It actually still has some of the additives present but if the process is done proper than the nasty stuff removed. The viscosity index, sulfur and contamination levels have to hit spec for the stuff to be used as a base oil.

Consider this, waste oil for the most part is added to the crude stream. Compared to the zillions of gallons of crude, the waste oil add doesn't make up much at all.

Think "the solution to polution is dilution!"

The Feds like you to use at least 25% re-refined oil to claim it is recycled oil. We actually make some engine oils using re-refined base stocks for the Feds and Military. You would be hard pressed to be able to tell the difference (plus in many instances the Gov requires certain branch to use only re-refined oil).
