Winter is coming to my neck of the woods. Here in Minnesota they require the use of oxygenated fuels during winter months to reduce emissions. This means 10% or sometimes more ethanol mixed with the gas. Will this harm my '90 G with the 3.0 M103 or is it modern enough to be exempt from this potential problem? I can find non-oxygenated premium but its kind of out of the way. Thanks for the advice on my 9/17 post. I haven't used any oil since then and haven't made any repairs. Knock on wood
