I think so. Syn would hold up a little better but a quality dino oil will be fine. My mother's car gets about that many miles a year, or less, I change the oil with Max Life every December when they leave for FL for the winter, it sits in the garage for 4 months, then she drives it on mostly short trips the rest of the year. It would still be good to give your SUV a good 20 mile run once in a while to warm the oil up fully. That's part of the issue. Does your Pathfinder do a lot of short trips or does it get driven a fair bit WHEN it gets driven and it's just not driven very often?
