Will it cause any known problems?

DRY GAS????

I haven't been able to get my rear end to seal over the gas receptical. Let us know if this improves your gas mileage.

This is a valid concern with the weather people are enjoying. Maybe someone with lots of rotary engine experiance can answer. I have been using 1 bottle of iso heet ,which is mostly alcohol, every other tank full to eliminate water that I may have
come across in the fuel that I use. Also driving in cold weather and parking inside warm will create water condinsation in the tank. Am using Chevron premium w/ techron. Have seen no ill effects but long term use info would be interesting to hear.
