Guys, My wife's 2003 Hyundai Santa Fe 2.7L has about 185K miles. It has had a steady diet of Pennzoil Platinum 10W30 over the last few years and M1 before that. I've kept to 6 months/7500 mile OCIs. Recently it has started using a bit of oil--I'd say about a quart in 7500 miles. I'm thinking about switching to Valvoline Maxlife. My questions are: 1) Is this a good idea? Or should I stay with the Pennzoil Platinum and just top up between oil changes? 2) Can I still maintain 6 month/7500 mile OCIs with MaxLife? Thanks in advance!
