Slight improvement over last tank. Made one long trip with it though (~100 miles), and it's still below my historical average of 27 mpg even before I started hyper-miling. Definitely thinking wheel bearing now, or some other issue, so need to investigate further.

About as bad as I've seen. Noticed some noise coming from the rear tires. Might be a bad wheel bearing, I'm not sure. Regardless, all trips less than 5 miles, so may just be the drop in outside temp and the commensurate drop in cold-start oil temps causing this. My new job has me going in before sunrise, so it may just be that.

Almost all city miles and very short trips. Have been shutting off the engine at red lights. Try to coast as much as possible between stop signs on back streets (accelerate to 30 and coast to the next sign). May have let one of the tires get low. Noticed it looked that way when filling the tank. Need to check cold before driving again.

Mostly city driving, some freeway. Have been staying at or below the speed limit, especially at higher speeds, to increase mileage. Ended up improving by more than 4 mpg over what I usually see on a tank. Also used 89 octane which improves mileage. I think it may pull less timing via the knock sensor, so I'm getting a little more power and efficiency.

Mostly city. Essentially a baseline for the way I have driven up to this point. Trying to see how much I can improve before trying modifications.
