2017 Subaru with the 2.5 naturally aspirated. Why did the oil change interval dip to 6k on these? The older Foresters were 7.5k, if I remember correctly. If I'm running Valvoline synthetic, can I run it past 6k? 4k of the miles are highway 75+mph in July road trip. I ran 5w30 because I knew it would be working hard. I picked up some NAPA today on sale, but am contemplating running 1-1.5k more instead of changing.
Opinions? Ideas? Past 60k miles, so no more engine warranty.
