Changed spark plugs for first time at 190,000 miles.
Replaced alternator at 210,000 miles for first time.
Replaced u-joints at 100,000 miles.
Replaced clutch at 125,000 miles.
Replaced air-conditioner pump at 80,000 miles.
This is the most reliable vehicle I have ever owned. Recently drove from Alabama to California and averaged over 30 mpg.
Isn't the most powerful engine and you need to turn off air-conditioner when you enter interstate highway until you get it up to speed.
I hope that you change your oil more often than you change your spark plugs!
The 1995 s-10 was the best vehicle I ever owned. It rode smoothly and I never had one problem. I replaced the brakes which is standard and the you joints at 95000 miles. I had a tune up done at 93000 miles. It got great gas mileage and even though it was a 2wd, I never had any trouble in the winter (in Montana). Great Truck.
