so the deal with the alcohol is to "clean out" the exhaust and catalytic converter system BEFORE you take a smog test. The theory is that by adding alcohol you increase exhaust temps enough to "burn off" gunk and old carbon clogging up your cat and head. After that you take your car over with top tier gas and hopefully pas smog under normal conditions. Im pretty certain that you wont pass a smog test running alcohol in your tank. Does it work? The theory sounds good but I dont know anyone thats actually done it and you risk actually melting down the cat into a solid exhaust block. Your best bet is to first make sure the car is set to exactly what it came from at the factory including timing (make sure your timing mark is visible) and a full tune up, use the best gas you can find (chevron) get the car completely hot and immediately pre-test it. If you fail a pretest find out exactly why and correct the problem for real. If you need a magical emissions test fluid your car probably isn't running correctly anyway

Yeah I get that the car has to adjusted right also but like I said above "high mileage" engines is why the alcohol peaked my interest.

Siteunseen and Mikes Z Car, I have been looking at this product also. I want to look at some reviews also.

Out of curiosity, is E85 available in the Peoples Republic of California?

Not around here where I am. I see all these flex fuel vehicles but I dont ever see any pumps.
