I only use oil that I know where it came from, no antifreeze or brake fluid with water in it though, glad you liked the idea, saves the money of return and provides about .25% increase in gas milage, cause I dont buy that quart, twice.

It works in 2 cycle engines so why not? Might be a problem with deposits (parafin) on the valves but the valve stems and guides would like it.
I wouldn't reccomend it in a state that checks tailpipe emisions. Seems like a lot of work but hey, every little bit helps until Senators Polosi and Reid stay home in their villas.
and..it is your oil. do what you chose.
