I have had my 98 OBW for almost 2 yrs. It started out getting about 24, got it to a consistent 26-28. Now it has dropped to 20-22! Yikes! Changed the plugs & air filter about 6K ago, and change the oil & filter every 3K. Any ideas of why my gas mileage dropped? Anyone else get this? What is everyone getting?

I did have a remote start installed, so my car idles more now, but it dropped before the remote....puzzled.

The oxygen sensor is probably tired. I replaced ours and saw mileage go up about 8%. A very easy DIY job.

Idling reduces mileage probably about 2mpg for me. Winter gas also reduces mileage.

will play some part. If my car varied that much from its 24-25 I would look for codes and see if it needed to be tuned up first, but I live in a mild climate.
How are some of you cold weather folks doing on mileage?

The best I know of is 34mpg in summer. Mostly highway driving. AC does not work, no power steering, those belts aren't even there.
It was funny, too: I had my GLF for a few months then and was just getting into things. I also was very tired and didn't pay attention to how full (or rather empty) my tank was. So I almost parked in front of the house, and the car dies. I try to crank it back up, doesn't work -- what the ...?
Turned out I just ran out of gas. The trip-meter read 520+ miles. So, IF the gas tank is 15 gallons (I'm pretty sure it is), then 34+ mpg is fairly accurate. And all that with the steering wheel bouncing and kicking at anything above 50 mph and unbalanced very old wheels. I am still wondering how I managed to cover almost 1.000 miles in 2 days and not break down!

I've only figured my mileage once since I bought my '01 in late November.

19+ mpg / mostly stop & go driving.

I normally averaged 25-26 mpg in my 97 OBW mostly driving to work via highway at 75-80 mph.

I've noticed it has dropped by at least 1 mpg in the last month or so, which I presume is from a change in gasoline composition for winter temperatures and the fact that you are pushing the car through denser air.

I will have to check the O2 sensor. I haven't thought about the winter time gas making it go down. Here's another question... how many miles can everyone go before they fill up? Who has gone the most?

Yeah I am on my first tank of gas around town and I have only gone around 200 miles and I have around 1/4 of a tank left. I just picked the car up last week so I have not been able to do to much measuring.

On my 97 OBW, usually between 330 and 375 miles. I almost made 400 once, someone who has the patience to drive at 55 could do it.....

I've had a couple of 400 mile tanks with my 95 Wagon (not OB). In my Honda Insight Hybrid I had a couple of 800 mile tanks, which is pretty extraordinary considering the tank is only 10.9 gallons.

I am averaging 27.42 US MPG from my MY03 XS Forester and that is
over 45 tank fulls (I fill to the neck everytime) and 12245.98 US Miles and due to where I live in Australia that includes the A/C running 98% of the time and I am not a slow driver by any stretch of the imagination.

Wow! I am impressed with the Hybrid gas mileage. That is incredible. Think Subaru could make a car like that? Very impressive.
