TRUSTY MUSTY Posted March 28, 2013 Share Posted March 28, 2013 FIRST POST! Is 19mpg normal for an '87 GL-10 Turbo wagon? I bought a really clean '87 GL-10 Turbo wagon with an automatic 3 speed transmission a couple months ago. The previous owner only drove it a couple hundred miles for the year he had it. It only has 123,000 miles on it (just a baby!) I'm not really getting the mpg's I was hoping for. I've been driving really conservatively, but I only average about 250 miles per tank (250/13 gallons =19mpg). My question is: Is 19mpg normal or is that low? I realize that pretty much anything that goes wrong with a car is going to hurt your gas milage, but is there anything in particular i should look into given the year and model? Any common problems out there? Anything with older cars in general that should be done to restore gas milage? SUPPLEMENTAL INFO -supposedly the fuel tank capacity is actually 15.9 gallons, but the fuel gauge says its empty at 13, so thats when I've been filling up again and calculating miles. -I also replaced the oxygen sensor and got a new timing belt. -I replaced the fluids when I got it and I've been using a couple different additives -new tires -One thing I've noticed is that the car doesn't coast very well at all. Even on a good decline, if I'm going 35mph and I let my foot off the gas, it'll slow down quite a bit, whereas in my wife's new forester, the car will continue to gain speed just from rolling down the hill. I'm a newbie and certainly no mechanic so please educate! Quote Link to comment Share on other sites More sharing options...
