Bought a 1999 Forester, MMO for oil?


Recommended Posts

Marvel Mystery Oil, is 10W-40 good for a forester in hot weather?

 

Okay, so MMO is Marvel Mystery Oil. Yea, I am aware of it. That product has been around for a long time. I have never heard anything negative about it, so if you have been happy with it, then I don't see any problem adding it to the Forester.

the 2.5 has solid lifters with shims for lash adjustment, unlike the ea82 with hydrailic lash adjusters. the idea of Marvel's Mystery Oil is to cure the 'tick of death' associated with cam tower o-rings or dirty HLA's in ea82's.

 

If you have lifter noise in the 2.5, shims will be in order next time the heads are serviced.

 

You could run the MMO through to keep deposits and sjudge from forming. Ideally, apply the mmo just before oil changes.

The 1999 Forester has the Phase II 2.5L engine, which has hydrolic lifters.

Ironically, the 2.5L is back to solid lifters on my 2006 Forester. One step forward, two steps back.
