I added oil stabilizer (20% ratio as recommended) to my mildly modified 1965 Corvair Corsa. I had a technical question. It seems that all things set equal other than adding the stabilizer, my idle speed is faster than before. I am a degreed engineer, so I put on my problem solving hat. The best I could come up with is that the stabilizer has reduced the overall friction between components. Therefore, at the given idle air/fuel ratio the engine is able to spin freer. Is this possible? I have no problem stepping down the idle circuit a bit, but I guess I never expected to see that much difference. If that is the case, hats off to a great product. Plus, since the car is air cooled, head temps hover around 400F under normal operating conditions. I figured normal motor oil could use the added bonus of the stabilizer when continually operating at elevated temps.

Any hint regarding the idle question would be appreaciated.

Again, what phenominal product!
