I have an 88 2.8 v6 and i am getting about 350kms per 55 litres of gas, i was wondering if anyone else has this engine, and if so if they can tell me if this is what they get for gas milage. So thats about 16 litres per 100kms or just under 18 mi/gal.

Might want to check out http://www.fueleconomy.gov/ for your answer.

i've got an 89 cutlass supreme 2.8l, hate to tell you but i get around 38 mpg on the highway

I've got an 88 celebrity and i get about 28mpg. from a very high milage 2.8

I don't have a V6, but I do have a 5.0 307 that gets around 19-23mpg on the highway.

im just courious but how could i increase gas mileage on my 85 cutlass. 3.8 l v6.
