I'm sure many of us have a story like this with someone we know from both sides.
My best friend has a '94 Chevy Astro van with a 4.3L.
The guy has 146K mileaga and is far from a maintenance buff.
In fact he goes at least 8-9K on conventional oil,usually running a qt or more low.
Changed the coolant once etc.
.
Yet the van is still running strong without any oil related problems.
We love our vehicles and long to go with the best products for our engines and yet others don't give a schlit and get lucky.
