shell premium is ethanol free too. (ontario)I did the same thing today, trying to avoid salty roads. I added some Evinrude 2 + 4 conditioner.
We dumped a lot of salt on the roads (my job) a few days ago, and much of it remains. To make matters worse, our Regional roads were all brined today.
91 octane at Crappy Tire does not contain ethanol; some others do, such as Ultramar. They recently decided to put ethanol in ALL their gasolines. I used to get my ethanol free gas there, but that's no longer possible.
I will never buy their gas again. Read the little stickers on the pump.
I washed salty dust off my wheels. I think next ride will be in Spring.
