I've done a lot of reading on here but haven't found much of what I'm looking for. I drive an 84 olds with a 76 350 Olds engine, but unlike most people worried about the ethanol in their classic car, this one gets driven almost every single day. It used to be driven about 100 Miles a day but now it's just in town about 10 miles a day and longer trips most weekends. Doing the math it costs more than $10 extra to fill with 91 octane that has no ethanol, while i can buy stabil marine 360 and it cost $3.25/tank added to a regular tank of 87 octane. The car does not require anything higher than 87 so the higher octane is a waste, it's just the only way to get 0% ethanol here in Canada.
The car gets parked for the winter with 91 octane E0 with stabilizer, it's just the summer time im worried about.
I'm wondering if I'm as safe using the additives specifically for ethanol gas, every tank full as opposed to spending $0.53 a gallon extra for premium. Maybe one day when I finally rebuild the engine with higher compression I can take advantage of using premium but for now this engine seems to just keep rolling on.
Last week my carburetor plugged up somewhere and lost almost all power. It's taken apart now and a spare carb is on the car for now, but I have to fix the original. About 2-3 years ago I had a carb problem and there was white buildup inside on the metering rods. Now I'm paranoid. I think the problems started when I no longer had a 100+ mile commute every day.
