Hell, with the discount after the carwash id keep doing that. Lol
Itll say in the pump "this product contains a maximum of 10% ethonal.
Yeah I just stick with brand name stuff. If its got ethanol than so be it but its gonna be better than all the cheap discount gases. Some say its all the same but I say there's gotta be a reason why the cheap stuff is cheaper. Now that you mention it though just for shits and giggles I think I will find a station that doesn't use ethanol and see if there's an MPG difference. Would probably take till the 2nd tank before the CPU makes any necessary adjustments to benefit from it.
