I run R-12 racing fuel in my Yamaha YZ250 2 Stroke. I usually mix 5 gallons at a time. At the end of each riding season I pour the remaining mixed fuel into my 1978 F350. I make sure the truck tank is near full to better dilute it and been doing this for years with no issues. Doesn't smoke, sputter or cough!

I fly Gas RC airplanes and If fuel is over 30 days I put it in my riding lawn mower.
synthetic oil would be better than petroleum oil on the converter, but we are dealing with a fraction of a percent so neither should make a real difference.
Simple answer go for it
