1991 318is mpg

Oh shit! the IS I had my eye on is gone. Crap, anyone wanna sell theirs?

Its pretty hard to get 30mpg stock. Since you got the 4.10lsd. your cruising at about 3-3.5k around 70mph. I was pretty compulsive when i was driving my 318is on long trips and managed 27-28mpg with tires at 35psi. calculating by fillup to fillup

I would get a taller gear though if your gonna be on the highways. Also its pretty obvious ALL the maintenance has be to be taken care of before you rack up the miles, bc shit just stops working randomly.

fwiw I just drove from Chicago to Purdue at speeds between 70 and 80 mph almost the entire way and managed 28 mpg on the turbo setup that is only about halfway through being tuned, and I had about 20 minutes of idling in traffic and maybe 20 more of driving in the city...

4.10 :p

IMHO the 3.73 is perfect for anyone who does highway cruising at speed. I like to run at about 80mph and that will put you at 3k rpm's. Plus your gearing is still good for city driving. I would not go any taller then the 3.73

already looking for a 3:73 even though i still do not have the car. :-)

fwiw, I would recommend a Mark Dsylva chip over the Conforti

thanks for the tip. Will keep that in mind

Ok, so bottom line is I could get over 30mpg in stock form. I did think of a Jim C chip though.
Anyhow, I will probably get a car allowance from the company, and I'll buy whatever I want. So I shall go the E30 route.
I think that my question has been answered. Most of the travelling will be solo, and 99% of the commute is highway.

I got 30mpg in a beat to shit, 260,000 mile 318is with a totally fried clutch.

[gearheadE30]

Mine got a consistent 26 city and 35-37 highway. Increasing speed kills economy real quick on the highway though

[naplesE30]

I used to get 29mpg like clockwork, 70%hwy 30%city with a 3.73 lsd and 205/55/14.

[freeride53]

I *can* get 30 mpg.
I have gotten ~15 mpg, with a full car, at speeds over 85 mph for long periods of time.

[mr.vang]

ohhh i see. i was about to bash you for putting eco box shit junk before e30 haha





a 2.93 makes a world of difference. Basically you go from 70 mph @ 3200 some r3v with a 4.10 down to 70 at like 2200-2500 r3v

i a need lsd now.. :)
