    What kind of mileage do the 87-91 EFI Suburban\'s get???

    I need to buy a truck ASAP and was thinking of a Suburban that I can eventually turn into a tow vehicle for my Jimmy. My question is what kind of milage do the 1987-1991 350ci EFI Sub's get?

    They probably still get better mileage than your 71'.

    No lift, 31/10.50/15 MT, 4.10 gears, Flowmaster exhaust, I get about 12 city, 17 on long trips. Towing? Couldn't say, but I bet it'd be about 8.
    I'll let you know how this next tank does now that its got the lift and 35s.

    BigGray said it best! THey don't go in same sentence! Like MILITARY-INTELLIGENCE or JUMBO SHRIMP or MARITAL BLISS (see HAPPILY MARRIED) or GOVERNMENT WORKER....

    On the other hand, on my 91, in various configurations, it's almost got to 16...(San Antonio to Colorado Springs) and as low as 6...(pullng the hotel)

    What if I do headers, 3" exhaust, high flow cat, the gas atomizer, tornado, TBI spacer, and a K&amp;N air filter? I should have about 1000hp and get about 60MPG with all those mods right!? /forums/images/graemlins/rolleyes.gif /forums/images/graemlins/rotfl.gif

    I think for any MPG over 50, you've also got to have the Hi-Mileage/Light-Weight GM ignition key too!
