I have 1999 sl2 wondering how many miles I should get out of a tank I do 90% highway 10% city not sure I'm getting decent mileage and if I'm not any ideas where I can get them back motor has been gone through many new parts if that helps

 

Go to www. fueleconomy.gov and punch in your information.

 

Transmission, automatic or 5 speed manual?

 

Sorry it's a auto

 

Go to the website I suggested and click on "find a car". It's really that simple!

 

My son has a 95 SL1 automatic. That car is the only one I've ever seen that consistently -- as in "always" -- gets better mileage than the EPA estimates. I don't think it ever averages less than 31, no matter the type driving, almost always gets 33-35 and has gotten as high as 37. It gets it's worst mileage in the winter and the best in the summer.

 

Just for a reference, I have an 02 SL. It takes between 9.2 and 9.5 gallons to fill the tank from fuel light just came on to first click on the gas pump nozzle. BTW, do not fill past the first click, you waste gas and you can damage your canister and purge valve if you do that a lot.

Typically from fill up to fuel light coming on, I go between 340 to 370 miles depending on weather, AC drops it to the 340 range. I have a 5 speed and I shift up before the upshift light comes on, typically between 2000 and 2200 rpm, but in third and fourth, I go almost full throttle and I shift from first to second as soon as I engage the clutch in first. I am typically going into third gear by the time I cross a typical intersection (2 lane).

You can expect about 3 mpg less if you are following good driving practices for fuel economy. You could get more if you follow hypermileing techniques, but I consider those dangerous so I don't do them.
