Are you still getting the same improved fuel economy? I once accidentally filled with 91 instead of 87, and it felt that I got substantially better mileage. However, as I continued using 91, the fuel economy dropped back to what is was (around 22 MPG). Not at all a controlled test, but wondering what your experiences are. If it's still going well, any idea which of those changes improved the fuel economy the most?

No, still getting the same have been running 91 for a couple of months now, still getting the same improved fuel economy , but lately not getting so good, head gasket is going out probably going to try replace next week or the week after. Going to school, so don't have time to do it myself. It's been getting worst now. I will let you know when I get it fixed. When I got the car, it had a head gasket leak, but it didn't use much oil. Now it's using quite a bit more so I will see. I tried the 91 10% ethanol that was the tank. Went back to.

Low 20s in my mixed commute (~4 miles 60mph highway then ~4 miles in town) 24-25 on the highway.

'03 NA 5 speed, no under-tray, slightly oversize crap mud terrain tires, and none-too-easy on the skinny pedal.

50/50 City / highway was 19 when I my 05 turbo 5spd last month, after injector cleaning and spraying out the MAF have been getting 22-23 driving the same route. Best so far was 24 with 70% freeway, but it still may needs plugs and the O2 sensor looks original.

Also, we use to have an 05 NA 5 speed, it was usually 24 normal driving, upto 27 on long freeway trips. Not great mileage but the NA's have pretty small 5th gears, so it would often run around 3000 to 3400rpm on the freeway. The turbo seems to run about 300 less for the same speed.

I've owned my '03 Baja for almost two weeks now. Just finished the first full tank of gas in it and got 19.4mpg. Mostly in town driving, some time on the interstate. Non-turbo, no mods, AC off, 5-spd manual, using 87 octane (10% ethanol), 142k miles.
