Fuel Mileage

[Dick Steinkamp]

I went on a drive yesterday with some new car buddies...

It was a gorgeous day with a beautiful, scenic tour on the back roads of Whidbey Island.

I clocked 180 miles. This is the longest I have driven my Bavaria at one time. The car ran great.

I had filled the tank before the tour and then topped off after the tour at the same gas station and same pump and same auto shut off. I had about the same number of miles at 65-70 MPH as I had at 35-45 MPH with some stops. 3.0, 38/38 Weber DGAS, 4 speed, 3.64 axle.

I know it is a very small sample. I got 16.7 MPG.

This is about what I expected. Maybe high teens with all highway, and low teens for city? What are others seeing with their E3s and E9s?

That sounds like it fits with my experience. If I get high teens on the highway, an OD should add 2-3 MPG I would think.

Your numbers are spot on. With carbs on my e9 it’s would do 12 in town, around 20 on highway. With b35 and five speed, 15 around town, 24 on highway going 75.

I have Weber 32/36s on mine and get about 14 in town and 18 highway.

Did 400 miles last weekend in my 3.0 CS with stock engine and carbs, longest trip so far, 16.7 mpg.
3.64 rear end ratio, automatic transmission.

I kept records when i used my e9 as a daily.
I did 4.5 km for every liter ( i think that's 10.5 miles /gallon), over a 20.000 km period.
It should be twice that when well setup; it wasn't ..... it even smelled like gas straight out the exhaust, and I drove it like I was 18...

 

[adawil2002]

3.0 CSi with a 4-speed, 17.5 mpg
3.0 CSi with a 5-speed, 24 mpg

Folks: Just a thought - please share differential ratios if possible. "3.0 CSi with a 5-speed, 24 mpg" is very encouraging! Are you running L-Jet?

 

[adawil2002]

3.0 CSi with a 4-speed, 17.5 mpg
3.0 CSi with a 5-speed, 24 mpg

Stock D-Jet with a 3:45 differential.

that is 22litre per 100km !!!

twice will be 11litre per 100km
that sounds good

I know. I wanted to drive more then have my engine rebuild/ carbs tuned/ work on it.
It set of CO alarms in local multi storey car park when I drove in. That woke me up.
