I am looking at a 79 Cadillac Elderado 2 door coup with an Olds 350 in it. Can anyone tell me what kind of gas mileage that might get.

IMO you would get a best mileage of about 25 mpg on the highway.

If this is a carburetor version, tuning the engine and making sure everything is working properly, especially the vacuum advance on the distributor will have a great effect on mileage.

thanks a lot for that estimate. if you could project what you wouuld believe to be the lowest that would get that would be great

I am looking at a 79 Cadillac Elderado 2 door coup with an Olds 350 in it. Can anyone tell me what kind of gas mileage that might get. I say 14 to 15 around town and 19 to 20 on the road if you are lucky
