I'm getting ready to go on about a 500 mile trip (round) in 40-70 degree weather. I've been putting Penzoil 10w30 (I think, anyways) in there.. the high mileage stuff.

Anyways, it's about time for an oil change, and I'm wondering what I should dump in her. Anything better than something else? She's got about 128,000 miles on her right now.

 

I use Mobil 1 Synthetic 10W-30.

 

Mobil 1 Supersyn Synthetic---10W30. You can't go wrong!
