I just dumped a can of it in my 74 gas tank last night right before I parked it at my MIL garage. It might be the last time I drive it this year? Hope not but I can't be sure with Cincy weather. I think last year I used stabil?
This past month I rebuilt my 25 year old eddie carb, it didn't even need it. My car sat with race gas in it for 16 years, so I know race gas is a good storage fuel.
But since I'm driving it a lot nowadays and race gas has gone up in price I rarely use race gas anymore except for my small engines.

BTW I get my prem gas from work and it has no ethanol in it. If I had to use ethanol gas I would store my car with race gas. No way I would store it with ethanol gas.

I have never put anything in my oil.
