Never used it myself, but for a 5K OCI any synthetic is more than good enough. Unless you drive down a long dusty back road to a job doing deliveries and idling all day in 110 degree heat, then tow a camper up a steep mountain each weekend, maybe.
Brace for folks telling you your OCI is too short, barring conditions described above. They are right for the vast majority of vehicles, I reckon. There are always exceptions. I also do short-for-syn drains---the current fill of M1 EP will be the first to go well over 5K if all goes well---but I drive a 15-year-old Saturn S....
Not sure. Maybe not as much addpack? Slightly cheaper base oil?
I see it comes in 0w20 as well Perhaps it's just the Mobil 1 that didn't pass the qa test for mobil 1 but good enough for the Mobil bottle
Using it in my accent right now. No complaints. Probably not gonna but it again unless it's on sale again for $2-3 a quart like when I bought it. There's plenty out there better or just as good for cheaper.
4k-5k OCI? Probably nothing. M1 might have something better like better cold flow, but as far as ability to protect over such a short OCI, I doubt M1 is going to protect any better than Mobil Super Syn.
I was going to use it in 0w20 in my dart next oci since m1 doesn't have the ms6395 spec to the best of my knowledge.iv read on here that it's a great oil in 0w20 so I couldn't see why it wouldn't be a good choice in 5w20.
