Cruze 1.4T Eco, M6 (Amsoil Synchromesh every 50k) 138k. Bought at 50k, originally started with PP. Switched over to M1 as it's often cheaper especially with the rebates, it can be very cheap and I figure it's pretty close/comparable to PP and I'll probably never know the difference lol. I have been using M1 0w30 AFE with 7500 mile changes for a while now. I read on here a while back that this engine just *shreds* oil and any synthetic is great, but the 1 or 2 UOAs I've seen show the oil was done at 7500, so that's when I change it. Haven't seen any UOA with any M1/PP
My question or situation that makes me want to ask for advice is a LOT of my driving is very short trips. I live 1.5 miles away from work. Work 7 days a week. Usually the furthest I drive in town is 3-5 miles away. That's almost all my driving. Now I do go visit my parents or go to an event usually 3-5x a month sometimes more which is 80+ miles one way.
I'm just wondering with this engine/my situation (turbo engine often on very short trips) am I better off running
M1 0w30 AFE (or maybe a normal M1 5w30 in summer? Someone also said not to run the 0w30 in a "cheaper/group 3 oil as it drives up volatility and increases oxidation?)
M1 5w30 EP (someone told me that's a bad choice for this engine, worse than normal M1?)
PP 5w30
I just run Delco filters as they have always looked great after use. I guess I want the best protection/oil that's going to last the longest. I know Amsoil SS is the answer to that but I don't want to pay $80 for an oil change when I can get something very good for $15-$30
So what oil/interval should I go with?
