Doogee,

We get about the same. I am always around 8-8.5. Out west when I was driving from Edmonton to Calgary I was hitting 6.5-7.7. Nice flat roads I tell ya.

I should also add that there are almost no traffic lights untill the last 30 minutes of the trip too. I'm not going back to the cottage this year so I doubt i'll be able to reproduce that with my typical driving habbits. My normal driving is 80%+ city.

Take a look at my odo readings and calculate it for yourself if you want...
My car is at 241587 right now so I won't need a fillup for a couple of weeks.

Those are the facts though, believe whatever you want.
easy there warrior.
I just said I wouldnt read too much into it unless you can repeat it. Its not like that normal mileage for you.(you hit 30's(31) ONE other time on all your listed fill ups) Its like running down the 1/4 mile and doing a 13.9 once but every other time you are running 14.5. i wouldnt run around telling people I ran a 13.9 unless i backed it up at least one other time.

why wouldnt you go back to the cottage again? its still august

I get 700+ on shell 91, and about 650 on esso 91 everytime, in Northern Ontario. That is with lots of hill, turns, etc. My 12km commute is like driving through the forks the whole way (minus the hairpin), and I do 120+ all the time but I'm very efficient (progressive shifting). Best I did was 750 on the drive up, with a bike strapped on the back, car completely loaded down, and on Hwy 17 from Sault Ste Marie to Thunder Bay (huge hills and winding roads). This is all with an s52 with fubar'd vanos and 3.15 diff. I can likely manage 850+ in southern ontario with an empty car.

Lol I didn't mean to sound aggressive. This thread is about the best mileage for these cars so I posted my best. If some one asks what i normally get I tell them 11-12L/100km. It's not like I was trying either, I was just tired and felt like a relaxing drive back home; no radio, windows up, fan on speed 2 (no a/c in my car). Everyone else was asleep and I was just chilling. I doubt I'll repeat this any time soon but I wouldn't say it was a fluke either.

My schedule is too busy for me to be able to go back this summer .

This is what I've been getting over the last year and a bit. I've got a stock 328i MT. Significant increase in mileage after switching to 89 octane from 91. The first few tanks were with the pre-cat O2 sensors swapped "bank 1 reading bank 2, and vice versa). The P/O had them installed incorrectly and it was a hastle trying to figure out why I had a rough idle and misfires...

Though somehow I managed ~15L/100km AFTER I fixed that. I have no idea how that happened.

Also notice the fuel prices here in Canada...

I think you're still consuming way too much. Maybe you aren't if there's a lot of city driving. And the 89 vs 91 thing I'm not convinced about. What app is that?

The app is "Gas Cubby" for iPhone. It auto-generates these graphs which is pretty nice.

You think my mileage is high? What kinds of things (other than driving habits) can improve mileage? Plugs, air filter... anything else? I'd love to get better mileage.

The really low points (high efficiency) are all highway trips. Toronto --> Ottawa runs on the 401 all the way. What's the most efficient cruising speed? 110? 100? 150?

Air filter, spark plugs and O2 sensors are probably the biggest things. 90 is probably the best cruising speed, so do 100 on the highway if you really care. To put things into perspective, even with the crazy driving on the cruise I still managed 7.8L/100km on a tank. I've never even hit 12+. I'm not even sure I've hit 11l/100km.

the most efficient cruising speed is 80-90. anything over it kills it

Well, having just picked this 325 up last week, I'm getting about 13L/100km on 92octane in the city.
-TMS chip
-Schrick performance intake cam
-Supersprint tubular header, and full cat-less exhaust
-K&N air intake
-Electric fan conversion (& upgraded water pump)

It's been idling weird, weirder than the cam should cause, as well as throwing a check engine light. Next couple weeks I'm going to replace all 6 coils & plugs, clean the idle air control valve, and do a full synthetic drive line fluid replace... maybe check on the O2 sensors too, and see how mileage is from there. Would like to see it below 10L/100km.

Coolant needs replace before winter as well, it's getting pretty weak. Bah, money pit xD

Check this before doing all of that maintenance. I had a weird idle as well and it was down to an O2 sensor (long story). It's best to read the codes and figure out the root cause before you throw money at it!

E36's are not money pits if you know what to fix and when to fix it
