Go back to cheap, engine-friendly, leaded gasoline, please.
Yes, leaded gasoline, that way we can have more low-IQ retards with health problems that end up on disability!
Yes is was better for the valves and piston rings but it really stank.
I had a 1976 Simplicity Snowblower that I ran leaded racing fuel(110 Octane) through. It had a Briggs & Stratton engine with a downdraft(piece of crap) carburetor. It was the only fuel I found that the machine ran well on. However, every time I got done with the driveway my clothes needed to be washed from the lead smell. Not to mention, smelling the exhaust probably was not the best thing for ME.
