Yes, the engine looks clean, but with a reasonable OCI I imagine that any oil would look the same. No one even asked how often you're changing the oil! M1 is certainly fine oil, but any top brand oil which meets the mfg specs is going to keep your engine clean and "work" just fine. If you find something @ a better deal, I'd use it with confidence.
It appears that you don't think you should stay with an oil that work's well for your engine, and in this case nearly 100K. Actually I have stayed with an oil that has worked well for me for the last 34 yeras in all types of engines in all kinds of conditions. Should I switch now to something differant?
I don't think it would matter, because I think all modern high-quality oils which are suitable for the application will work well. You obviously have an emotional attachment to M1, so you should keep using it if it makes you feel better; but I don't believe other high-quality oils would work less well (or better).
Sorry, no emotional attachment to M1. It's just been the results I am attached to. I also agree that most of the modern oils will work well. However I would not run the 10K OCIs I do with all oils.
Come on sir, that's somewhat delusional. The guy was creating conversation that is actually quite liberating.
So, should the OP have a heart attack, sell the car, or immediately suspect increased wear or engine cleanliness being automatically compromised from 'ever' using another oil rather than Mobil1?
I think you missed the point of JOD's contribution.
Was this a thread about an engine with 97k miles or M1, anyway?
Says a lot about the engine, and definitely nothing but positives for M1. However, it says more about the engine and maintenance habits of the owner. This includes but is not limited to using a quality oil at obviously reasonable intervals.
