mileage and gas mileage of your m20

[PNWDan]

M20, 70k miles
chipped 173
29.7mpg@70mph, distance: 40 miles
4.10 open autotragic
16 x 7 50 series tires

Curious..what do you average on a tank with the 4:10

[bernzpeed]

i just recently had the chip in and have not driven the car for that long. But before the chip, I get about a range of 270 miles on a full tank, and about 22mpg 65% city driving, 24mpg highway
also, i have not changed the fuel from 87 to 91 coz i still had a full tank when i installed the chip

benzspeed definitely has the bes gas mileage what is the chip you have?

you have an auto and a 4.1 and you got 29 mpg at 70.

where as I have a manual 3.7 and I got 28 mpg going 800 miles at 65.

Thats what Im talking about , now I can figure out whats better about your car?

You know as far as highway runs, I have definitely heard that bigger rims help and you have 16 and I have 14s.

If thats even 1 mpg I cant fight it off anymore I need some 16s.

e34 B25, about 13 MPG

[stamar]

on the freeway or overall?

auto manual etc.

thats good info the m20 in the e34...I love the e34 Id trade tommorow.

[paperplane94]

Its an automatic, you can certainly do better with a manual.

13 is mostly city driving, more like 18-19 on the freeway just by reading the OBC.
