I could see to some extent if working with a dirty neglected engine, however I doubt most of the BIOG member engines come near that definition !!
The reason I ask is not to hijack the thread, I just see so many thread recommending adding MMO for a range of things to thin, clean, general additive to every OCI, and to clean which I can see the cleaning part, and winter use.
If you believe what is said on some sites who sell products that directly compete with MMO, even a good oil can leave deposits in some engines. I happen to believe that statement. In ideal conditions with an engine that is not sludge prone, people can and do run 100's of 1,000's of miles with no issues what so ever. Then there are people who use their vehicles in severe service short hops, you name it, and even with a good OCI routine develop junk in their engines. Also people buy cars with unknown histories, and want to clean up the engine because they think it needs cleaning, or it really does need cleaning. They might actually be able to determine that by looking into the oil fill hole and seeing for themselves. MMO happens to be a good product for this. I does slightly thin oil, other products thicken it, at their suggested rate it doesn't take oil out of grade.
As far as adding it to the winter time, it does help in cold weather starting, and in extreme cold [at least for me, more than once] was the difference of starting and not starting. On a few occasions in the Adirondack mountains -35*F it drastically cut down on the sickening noise a cold engine with no pan or block heater makes after sitting several days. Is it for everyone, no especially if you're dead set against additives.
I've suggested more than once to people who might be on the fence about using MMO for fear of it thinning their oil, to use it in the winter when a slightly thinner oil is a plus. Does it have to be used every OCI? Not really. Once a year, or a pint for the last 1000 miles of an OCI, you name it. Every seller of additives wants you to use their product as much as possible. But that is your call. For the money I feel it is one of the best products on the market. JMO

why not just use motor oil?
In over 35 years of using it that is the first problem I've ever heard or read about MMO causing a problem. Sounds like a HP application so there could be a lot more to this story. But then again, there's a first for everything.
I'll stick with it.
