Wrong thing to ask. You'll gonna get ppl saying its gold. Ppl saying its a waste and ppl saying they love beer.
Ill tell you my experience. For my last oil change before my winter oil, i did 5 qts rotella and 1 qt MMO and usual oversized gold filter. After i drained and ran 530 for winter, my engine is quiet and runs smooth. I have no negative comments

Like jeeps I heard it was the best thing since sliced bread. But I already know jeeps are worth the money. I'm just asking if marvels mysteries oil is worth money. Is their a better oil?

What do you see when you shine a light into your oil filler hole? Sludgy? If so, use 5 quarts of Rotella T3 and a quart of MMO and monitor the progress through the hole. use a Wix or Napa gold filter.

I ran in like 1000 miles or so. I was running 10-30 t5 when i did it since it was fall. Cruiser Will say if you should do 5-40 for the winter. I dont recall if 5-40 is thin enough as 5-30

Well for my climate area, winter isn't much of a winter.. lows in the upper 30s. The engine is all original as far as I can tell and has 236k on the clock. Oil pressure seems to be fairly consistent at about 15-20psi at idle on the mechanical gauge, so with that being said I wouldn't mind running a 10w40 weight oil with a Wix filter. Does the MMO make that much of a difference as a safe "crankcase" cleaner? I'm just a little skeptical about using additives like that. I would think routine maintenance would benefit more than additives might.

All i can gave you is what happened to me. I've MMO the engine as well as i did 2 internal steam cleaning of the engine and she rides smooth. Only issue have is needing a damn sye to stop vibrations as i drive
And like cruiser said, take a peak into the top of the oil hole. See how it looks in there.

Leave it in for your normal cycle of oil changes. Monitor the progress using a flashlight through the oil filler hole and the oil condition on the dipstick.
