The 1982 S-10 I have has a four cylinder Isuzu motor. I had a problem with a bad head a few years ago. The truck was put out to pasture for 3 years before I got around to putting on the new head. Where the water was in the number three cylinder for those years there is a nice groove in the cylinder. Due to budget concerns at the time I cleaned it up and drove it. If I run it without the Lucas it smokes like the fog machine they use to spray DDT on us with. It also fouls the plug in a few hundred miles and uses a quart of oil every few hundred miles or so. With the Lucas at an oil change there is very little smoke when it first starts up then not so you would notice. The plug doesn't foul and the oil consumption is normal for a Isuzu motor with 160,00. I have been using the truck pretty regularly for eight years like this. I am a sold customer. The S-10 is on the rebuild after the 52' list.
