2005 (really 04) Caravan, 2.4L 4 cyl.
Pennzoil YB 5w30 Make up oil: 12oz. @ 3K
Miles on Oil: 4,000 (VS. 3K ON FIRST 3)
Miles on Unit:79,000
Warranty over, upped OCI from 3K (Chrysler severe service) to 4K. Winter OCI (Jan. to April). 75% short trips, wife idles to pre-warm. Looking for fuel dilution, etc..
BLACKSTONE COMMENTS: There was a mild rise in iron after the longer oil run......Running this oil 4,000 miles did not harm your engine at all....you could likely run 5,000 miles without any significant changes to engine wear. The oil's TBN was 1.9, so there was still some active additive left for a longer oil run. Oil viscosity was in the 5W/20 range again.
MY COMMENTS: My concern about severe short trip driving in winter were unfounded. Nothing alarming here. Happy camper.
