E30 Gas Mileage

[nukeduster]

Just curious to see what kind of numbers you get with which engine and what kind of driving you all do?

I drive about 130 miles a day, 90% of the driving is 80-100mph and average 21mpg in the '89 325i automatic.

I only use 87 octane fuel, she has 169k miles, and now that I replaced damn near everything other then the actual engine, still runs great.

well i drive about 60 miles a day, most of it is around 80-90 MPH i think i get around 20-25mpg on my 89 325i 5spd

[Numark318i]

e30 318i
I get about 40mph on the highway at 80-95mph
25 on average though.

Do any of you know some form that i can use to convert miles per gallon to kilometres per litre?

[whitey_E30]

21.5 mpg on my 325is with 92 octane.

91 318is & it is need of a tnue up. I am getting 33 Mpg right now on 87 octane. I am planning on trying diffrant fuel grades to see if there is any change in gas milage.

'85 325e 4spd auto driven imostly in the city, average speed likely 55-60km/h. Depending on my driving style (it varies greatly) I get between 8.75 to 10kms out of a litre of fuel.

325e using 93 octane,
55 mph: 37-38 mpg
75 mph: 34.5 mpg
Mixed: 33 mpg

Not too bad for a 20 year old eta.

Not to start an argument, but wrongo. On the highway they were rated for 37mpg, wheras in the city they only managed 25mpg, both figures with a manual tranny. The automatic only dragged it down about 1mpg in both accounts. I can post the Motor Trend article to prove it if need be.

actually, i'd like to see a motor trend e30 article =)

[offabroadway]

Whoops. The real numbers are actually 22 city/36 hwy for the automatic. Here's the article, I've seen it on various sites as "Originally Appeared In Motor Trend" I think. Could be wrong, but I know it's out of a magazine. Whoever put it up even scanned in the pics for us.

325e Article

Enjoy!

I know this is reviving an old post but I wanted to add the following link:

BMW 3-Series Gas Mileage

This site has mpg, as stated by bmw I imagine, for every 3 series BMW from '78-2008. The 1984 BMW 318i, manual, has the highest stated MPG of any 3 series, 27 city/ 38 highway.

What changed in the 318 between '84 and '85?
Do these numbers seem accurate to you?
Seems like members here are getting different results.

I use my 325i for mainly city/traffic driving. I average like 18mpg and drive about 20-30 miles a day.
