taz ride Posted September 8, 2011 Share Posted September 8, 2011 I just bought a 87 GL 10 turbo 4x4 wagon with 58000 miles on it and wondering what kind of miles per gal. to expect???? I am not new to subaru. The wife counted up that we had a total of 7. The subie wagon makes # 8. Any idea of life expectency. I have added 4 new tires and new front axles. New plug wires and rotor cap and dist. cap are next. The subie has air adjustable suspenion, and everything works but the a/c. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted September 8, 2011 Share Posted September 8, 2011 there's quite a few mileage threads. by 4x4 do you mean manual trans? trans, type of driving, foot in the turbo or not? 22-28 - less or more is possibly depending on driving style.

soobie_newbie67 Posted September 8, 2011 Share Posted September 8, 2011 damn gary, right on the spot for me. im getting 22 in town and, well actually 31 on highway, but thats cause im going 60 and keeping it below 3K rpms. they dont do too bad, but i've also gotten my 1988 GL-10 turbo wagon (5 speed full time 4 wheel drive) down to 15 MPG by hot rodding it all day long.

man on the moon Posted September 9, 2011 Share Posted September 9, 2011 I think the lowest I've ever gotten is 21mpg going through the mountains having left a vacuum line undone, resulting in a super rich mix in the intake manifold. Oops. My current commute is about 50/50 city/highway (25 miles total) and I am getting just over 27mpg per tank, so I figure about 24/31 or so???

taz ride Posted September 16, 2011 Author Share Posted September 16, 2011 Update, I just changed the plugs, plug wires,rotor and dist. cap and went from 17 mpg to 22 mpg. This is a big increse in mpg. Hope for more mpg but this is a start. BTW this is local driving only, no trips yet. Quote Link to comment Share on other sites More sharing options...
eulogious Posted September 16, 2011 Share Posted September 16, 2011 My 1990 turbo auto car got 24-26 TOPS on the highway, and about 20-22 around town. Plugs and wires help. But your 22 sounds about like what you should get with that turbo around town. Oh, and this was with 92 octane gas as well. If you are not running premium, start running it, the engine runs better with premium. Quote Link to comment Share on other sites More sharing options...
tundrabrat Posted September 16, 2011 Share Posted September 16, 2011 If you are not running premium, start running it, the engine runs better with premium. Ugh...I don't think I can stomach putting prem into my 26 yr old car...maybe after I rebuild the motor. Quote Link to comment Share on other sites More sharing options...

Do keep in mind I am talking about turbos only, otherwise it don't matter Quote Link to comment Share on other sites More sharing options...
idosubaru Posted September 16, 2011 Share Posted September 16, 2011 i don't even put premium in my H6 OBW where it's "recommended" i have a couple times but didn't notice a difference. not paying much attention to performance in a big honking family wagon though.

l75eya Posted September 17, 2011 Share Posted September 17, 2011 I just took my 87 gl 5spd 4wd on a 7,000 mile round trip to nevada and back. Background on this car, I bought it in April, it had 42,000 miles on it. I put spark plugs in it. I replaced the front wheel bearings. I drove. Averaged about 25 mpg most of the time. This was with about 1,000 lbs of people and luggage and bikes. The lowest I hit was 15 mpg going over the mountains in Wyoming. In 3rd gear. Barely keeping pace at 40 mph. hahaha good times. That was all premium gas too. The gf's 93 Loyale has 70,000 miles on it only gets premium gas, auto trans and usually averages about 22-25 mpg. the 3 speed really kills it on the highway though as 65 mph sees the engine at about 4,000 rpms.
