After reading a thread or two the last couple weeks about Premium vs Regular Unleaded gas, I put a full tank of regular in for the first time on Friday. Now here is the "am I going nuts" part. I could swear that my 99 ETC is running better on the Regular gas. I can't put my finger on it exactly, but it just seems faster/smoother/quicker or something to that effect. So tell me what is causing me to notice something that doesn't seem possible.
