Hi, Looking for a little help/advice. 1995 Blazer 4X4 4.3L, 114,000 miles. 3.42 rear end gears. Recently purchased with 110,500 miles. Only getting 13 to 14.5 mpg around town. I checked almost every tankful of fuel( miles driven divided gallons used). It runs good now after all the repairs I have made (See list below). Am i wrong to think it should be getting better mpg's. I don't have a really heavy foot either. I did a compression test before I bought it, All cyl's between 135 and 150 PSI. It used about 1/2 qt. oil between its 3,000 mi. oil change. Never really had it on the highway for more than 40 or 50 miles on a tankful to give a accurate Hwy. figure. No DTC's set. Here's what I've done to it so far.
1) New plugs,wires,cap and rotor. All AC Delco 2) New air filter 3) New Fuel Pump (because it died) 4) New 195 degree t-stat (just because) 5) New Central MFI AC Delco (it was leaking) 6) New O2 sensor 7) New exhaust sys. from cat back (muffler rotten) Thanks In Advance Larry- posted
