This truck got 28 MPG on the highway. It always was comfortable and dependable on long drives. It had the X motor in it so it never lacked any power. On corners it held the road very well and hills were no problem. It was a great little truck.
I bought this basic model (auto trans) two years ago as a utility vehicle and I've put 20k miles on it- still low miles (72k) but I'm starting to see some of the same issues as mentioned in other posts. (tranny, leaky fluids, etc). I don't rely on it further than 50 miles from home. Horrible mileage and no punch at all.
I have owned this truck for about a year now. I love almost everything about it. The 4.3L has plenty of power compared to my earlier 87 s-10 with the 2.8L. This truck has almost 400k and does not owe me a thing. The one thing I would change is more durable cloth on seats especially on driver side. Recommend the S-10 to anyone so far best built compared to ford and dodge.
This is my second s10 and both have had a SEVERE lack of power, to the point where your leg hurts after going up any little hill. The 4 cylinder is known for this, but these were the 4.3 v6 models! The problem is with the prehistoric overhead valve design the GM still puts in nearly all the vehicles even though every other manufacturer has moved to overhead cam design. If the previous owner didn't change their oil every 2000 miles or sooner, the lifters will mess up by 100,000 miles and the only fix will be to pump $500 into the engine, or buy a new engine altogether.
S10 had 4.3 V6 and 5 speed manual transmission. Front brake pads don't seem to last long on this truck. Neither did the Delco batteries. Replaced battery 3 times in 6 years. Major problems began at about 45,000 miles. First the altenator dies. At 50,000 miles the transmission craps out. Transmission, clutch and slave cylinder were replaced with new one at dealership. AC quits working a couple months later. About 14 months after having new transmission put in, the transmission starts messing up again. I took good care of this truck. It had regular maintenance and was not driven hard, nor was it used for towing and hauling heavy loads.
