i can certainly tell the difference in my L36 SSE when I use mid-grade (89 octane) vs 92 or 93 octane premium. My throttle response, mpg'*, and power all suffer. I've only used mid-grade on 3 tanks, two consecutively, and when I went and ran two tanks of 93 after the 89 I could feel a significant gain, plus the temps were warmer (35* vs 0*-15* ).

I've been running ethanol blend (10%) in every car I have owned here in Iowa for the past 20 years, and have never had a fuel-related problem traceable to ethanol. Did get some water in gas once that really caused problems. Never been back to that station.

The '92 SSEi runs nice on 93 premium Mobil ethanol blend. Gets 22 mpg average. I try to fill at the same station, same pump, whenever possible. This Mobil gas is sold at a Jiffy franchise.

The day before yesterday I filled up with Holiday gas completely. I was bored today so I decided to run the tank. I ran 335 miles of mixed driving. I redlined probably 10 times and did some sustained cruising at 90mph. I also drove under load meaning up hills at low rpms. Under load was smooth as usual. After I got back I checked my oil and plugs. The oil was clean and the plugs were good, no carbon or anything. I recieved 25mpg on the tank. So far so good.

Best i've averaged with my car was 27 mpg on a highway for about 230 miles straight of driving 90 with the occasional small town.

With my around town driving, I seem to be able to average right around 22-23 mpg. I tend to fill up wherever is cheaper (for 91 or 93 octane), but as soon as my dad (and the other investors) get their ethanol plant up and running in Central NY, I'll be purchasing 10% ethanol blend everyday to support them. This plant will be run by local (to CNY) farmers and will be a big boost to NY agriculture. That'* primarily why I know as much about ethanol as I do.

The last trip the wife and I took was down to PA to her great grandmother'* place for Christmas in October (yeah I know, kinda weird, but she doesn't want anyone driving in crappy weather). On the way down, I averaged 25.2mpg over the course of 560 miles. On the way back on the same roads (~560 miles) my wife drove and averaged 27.3mpg... I guess I'm more of a lead foot than her. We drive about the same speed, but I guess it'* all in how you get to that speed.
