Unhappy w/MPG

Recommended Posts

I purchased a '91 Reatta, last summer and I wasn't very impressed with the mileage it ranged anywhere from 18 - 20 mpg on the highway. I have owned a LaSabre and got upwards of 30 mpg. Any suggestions? I have used different brands and grades of gas with nil results. Other than that I really am impressed with the vehicle.

I have 2 , 89's and had a 91. The 91 got about the same gas milege you report.(89's get 28-32)<BR> My 91 ran at about 400 rpm higher, in top gear, than the 89's. Different gear ratio's, I'm told.<BR> I will watch this thread for suggestions re. Oxy. Sensor, cleaning throttle body, etc.?

Mileage should be vastly better, you did not mention what if any maintainance you've done, basic tune-up, Air filter, fuel filter, plugs etc. Most likely your Oxygen Sensor is causing the poor fuel consumption but you've got to do the basics first.
