iam wondering guys and gals whos owns a bonneville with a 3.8 series2 (non supercharger) how many miles are you getting with a full tank of gas? in city? and in highway?

With my crazy driving 350 miles /tank. But that'* only 19mpg, and that'* horrible. But, this is all city driving. I think once I get my car back on the road, I should be getting 450 [25mpg]. I know a lot of members have seen 30+ mpg on road trips. But, that'* feathering the throttle, and we all know how hard that is to do on our cars .

I have a L27 and I have seen 32+ mpg,

I usally get about 275+ on the road for a half a tank

320, full to empty on 98 ssei (all city)

If I recall correctly, my old Bonnie did over 20 in the city, and close to 30 on the highway. I don't know the range.

THere must be something wrong with our bonnie.

I haven't seen it get over 18mpg since our last road trip (which it got about 28 ).

But I guess that is to be expected when you have parents like mine who don't take care of the car.

Do it all, plugs, wires, clean the TB, and put in an O2 sensor. NOT BOSCH.

I have begun doing the oil changes myself because I couldn't get my mom to do them at 3000 miles...

anyway 17mpg equals about 260 miles per tank and 285ish if you push it so there are probably 2 gallons left.

I get at least 400 miles to the tank with combined driving in winter....more in summer...i use synthetic oil.....makes a big dif...

I get over 300 per tank in the summer. Now that it'* cold out, tho, I use the wussy button (remote start) too much, so my mileage has dropped accordingly....
