The company I use to work for had a fleet of Chrysler Mini Vans (I think they were 1993 models) 4 cyl. automatics.
I use to drive one from Akron Oh. to Pittsburg PA. everyday (4 hour round trip) and it had over 350k miles on it with no major mechanical issues.
They would change the oil and filter on them religiously every 3k miles.
The company started getting real "cheap" and started changing oil every 7500 miles just before I quit. I noticed a couple months later they wound up purchasing a brand new fleet of Vans.
