I got an 89 olds 88 and gets 16 around town and 27 on the highway. I made several five mile tests on a recent trip on speed and air conditioning usage in a 2002 Cadillac. We got it up to 32 MPG at 60 MPH and no air conditioning. The owner threathen to kill me if I didn't cut the air back on. The AC takes up 2-3 miles off and over 60 MPH took another 2-3 mpg off. So we kick it back up to 90 with AC on hope for the best.
If it is a 1997 it is 18 gallons
I'm currently getting 34 MPG highway and 28 city. My 88 LSS has 120,000 + miles on the original engine, and still runs perfect!
18 US Gallons.
I get about 30 miles to the gallon with my olds achieva.
19 gallon tank.The AVERAGE fuel mileage is 20 MPG on the 3800 generation 2
It is necessary to know the fuel tank capacity of a vehicle. The fuel tank capacity of a 1968 Oldsmobile Delta 88 is 20 gallons.
See link.
The stated gas mileage is; 23 mpg on the highway, 19 mpg in the city. The actual gas mileage is dependent upon the driver and the driving conditions
you may have changed the tire size which will give you incorrect mileage hence causing an erroneous gas mileage reading.
20 miles to the gallon
i believe above the gas tank which means you would have to pull the gas tank out before replacing it
Oldsmobile no longer exists, so this is based on historical data. The Alero seems to have the best gas milage of the 2004 cars, which was the last model year made.
