i have owned my 95 3/4ton 4x4 suburban for about a month now and finally figured up the gas mileage and got a whole whopping 5.5 miles to the gallon. I do let it idle to warm up some most days but not much more than five or ten minutes. I drive through my smallish and never have to sit at a light long. I only drive about 6 or 7 miles with longer trips on the weekends and most of that is at 55. The thing has 4.10 gears with 265/75r16 tires. The plugs and the cap and rotor didn't look very old and I gapped the plugs back to .35 and that seamed to help the got up and go a little. It doesn't have a cat but has the factory y pipe and a new muffler and tail pipe. The the drivers side exhaust manifold is cracked. The evap system is plugged off because the previous owner didn't hook the hose back up to the vent when he replaced the fuel pump. The fuel filter looks recently replaced. It only has 140k miles on it. For compairison my 2011 1/2 ton crew cab 4x4 Silverado got 11ish with e85 doing the same route.
I have a new O2 sensor for it as that looks like the factory one. Has anyone had one get that bad that it drops mileage? Is there something else I am missing? At this rate I should have gotten one with a 454 instead of a 350.
The guy that sold this to me boned me good. It was dark and I didn't have much time to work on it. He covered a lot of stuff up. Good thing I only gave 2200 for it.
