Ok I use P4 ultra 5w30 in my Cruze. I was working an hour from home at an Audi Dealership, averaging about 900 miles a week give or take. I was getting about 12-15,000 miles between changing oil with a filter change in the middle with great TBN and wear numbers. Now I work 3 minutes from home so the car isn't even at Operating temp by the time I get to or from work. This is the 1.4 turbo. My question is with me short tripping now, what should I knock my interval down to at first?
