Re: 100:1 Mix
That's interesting input, and it might have some validity. There used to be a product out there, sorry, can't recall the name,was in the 60s, but it was formulated to quiet noisy hydraulic lifters. It worked great, as long as you used it but if you stopped using it the lifters would collapse requiring replacement. The concept isn't the same but I'm not going to be the one to test the theory. My engines are running great on the Opti-2 and unless it is no longer available I'll keep using it. By the way; Opti is blue and your fuel mix will be too.
