well I tried three gallons as I didnt want to get stuck with a tankful of under preforming gas and I did feel what you said it dosent preform as well. after driving it for a while I promptly filled the tank with Premium.

There was a very interesting article in the Milwaukee Journal yesterday regarding problems with declining fuel quality apparently even in some premium brands that really goet me thinking and reinforced the need for premium in my Acura. the detergent levels in tsome gas has been causing problems for many fuel injectors and it specifically talks about hondas as being one of the affected brands.

looks like based on this until they start naaming names I'm going to stick to Shell and Mobil premium wherever possible.
