17 mog highway! i win! but seriously, wtf is going on? i got a checkengine code of 1221 and it said something about the o2 sensor. i changed it. nothing improved. the light is showing the same code, so what else could it be? could i have goten a bad 02 sensor to begin with?

trade it in on a new Civic.

Is it ok to say KMA on a Sunday. I rode in a Civic this past week, it's no E34.

I got 25 mpg from SFran over the Sierra's then 28 mpg across Nevada. Ran 80 mph to keep from getting my first ticket. Looking forward to a high speed blast on some of I80 this summer to check on my dad. BTW, Happy Fathers Day to all.

Well guys, I got just an old '91 520i M50 with manual tran. with 180.000 km in it, plus 17" Borbet rims, with 235/45 tyres and somehow manage to get 33,5 mpg at 70 mph (with wife, kid and some luggage a/c off). Previously I owned '82 E28 520ia, a real petrol guzler, but I was surprised with my "new" E34.

i guess that would make you das winner then :^) i asked because they don't sell the 520s in North America, assumed it was british market car. I made my car a m50 525 into a 516 when the computer died and I had to shut off cylinders 1 and 6 to drive it to miami....gutless piece it was! and the worst part was that i only got about 25 mpg doing it!

Seriously, other than the rim and tire thing i got only a Remus rear muffler and thats about all the modifications I have in it. I use 10w40 synthetic, 95 octane unleaded fuel and every 2k miles I add one Liqui Molly injector/valve/everythingcleanerstuff to a full tank of gas. Change air filter frequently ... oh, and check the tire pressure on a weekly basis.
