I am mixing at e15...right out of the pump so to speak so it isn't old. I'm wondering if we are still on winter gas here. Honestly I'm not overly concerned about the part throttle knock as it's 4 degrees or less typically. It's just affecting my LOR which is irritating.

? I wish they had cheap & accurate (yes I want it all!) ethanol level testers you could use to regularly test pump gas ...
