With the addition of 10% Ethanol and more to come, the only way to get the octane we need is to drain the tank each spring. I parcel it out to the modern cars, a little at a time and also use it for the lawn machines. Trouble is, my Kubota is diesel so can't use it there.
I've had mixed results with Sta-Bil (gummed up the carbs on some lawn equipment) even though some swear by it.
My Audi has an ECU that adjusts for the loss in octane that occurs over winter storage. I still try to fill it with premium first thing in the spring but that's now only 91 octane here.
But the 3A likes octane and pings until I change it out.
So ... question is:
Is there a stabilizer for gasoline containing ethanol that also prevents it from destroying the rubber seals in the older fuel systems? Sta-Bil has a new marine fuel stabilizer - is that a better product for our vintage engines?
