Just curious as to people's preferences for high mileage oil for a 1992 Chrysler Town & Country 3.3L. I usually get my oil changed at Firestone, so I get whatever they put in, but it seems to wear out faster than one would expect. If I have to top it off at all I usually use Castrol GTX High Mileage 5-W30 (or is it 10W-30? Always forget and have to look in the manual...)

I'm planning on doing my own change this time around, so I'd like to use something that is going to last and do a good job.

Tanks.

 

I've had luck with Castrol. I usually run Valvoline, I've had the best luck with that. If it ran conventional stay with it. My .02$
