Hi guys, I have a 2022 T7 and I'm changing oil roughtly every 5000 Km as I'm ridding quite a bit offroad. I have this leftover from previous oil change and I notice one is full and other semi synthetic. Is it safe to mix ? I'd like to finish those two in my next oil change. And also does oil age after 2/3 years of storage ? Thanks a lot and safe ride
