Is it worth the money?

 

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.

 

This is exactly what i did.

It works well

 

Sure does. It ain't no "mystery", is it?

 

Other than smelling good. Nobody knows what it does.

 

How long do you typically run the MMO with the Rotella oil? Just like a regular interval? Also, what weight Rotella?

 

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.

 

I can't ever see a can of this stuff in the store without hearing Paul McCartney's voice in my head singing, "Marvel Mystery Oil"

 

Lol it didn't break my jeep

 

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.
