Over the three years that I've owned the truck, I've run Purolator, AC
Delco, Fram, and Autozone's Proline. No difference in behavior with these
filters, and they've all been completely full of oil when it comes time to
change the oil.

And make sure to never wipe a gun down with oil... acid-etched finger marks
are a good thing.

Cleaning really dirty stuff *too fast* is bad...

now if the engine looks clean inside (pull a valve cover) go for it, but
if it's all sludgy and nasty you are rolling the dice with an engine
flush... take it easy with the harsh stuff... maybe try switching to a
high detergent oil like Rotella or something instead of the flush

I also have a 2002 chevy S-10 W/ 4.3. I work for an Electrical
Contrator that purchase hundreds of S-1O’S & Astro Vans. The only
problem we here regarding these Vehicals are the brakes ( front ). The
GM factory brakes and rotors seem to be of low quality. As far as the
4.3 its Bullet-proof.
