I am also interested in finding out whether you have noticed any difference if you switched between Premium and Mid-Grade. I have used Premium and Mid-Grade, but since I don't push my car all out all the time, I don't know that it really matters. If I buy Premium, I feel that I am just spending $.10 per gallon for nothing.
Comments??

I just wanted to bring up a little flaw in your logic here. First you pose the question of "whether YOU have noticed any difference ... between Premium and Mid-Grade [gasoline]". The whole point of premium gasoline isn't so YOU can notice a difference, it's so your CAR can. It's not magical horsepower juice, its cleaner gasoline for high quality engines. Your car isn't a lawnmower, its a lexus.
Secondly your reasoning behind not using premium on top of "not noticing a difference" is that premium costs $.10 more per gallon. I drive more then probably anyone on these forums, or at least in the top 2%. I commute 72 miles each way, 144 miles a day, 4 days per week (I work 4-10's). Just commuting to and from work that's 576 miles a week, and 29,952 miles per year. This doesn't count going out, road trips, etc.
Lets assume I get 26 miles per gallon. That's 1,153 gallons of gas I have to buy per year. The difference between Premium and Mid-Range per year totals out to $115.30. That's a small price to pay to ensure your engine is running as clean and efficiently as possible. Odds are you, and most people here, drive half of what I do, making that total closer to $60 a year.

The Bottom Line: Put premium gasoline in your IS.
