Marvel Mystery Oil

This goes back many thread/posts ago and maybe somebody already posted....

But Eq Sys advised me to drain a quart of hydraulic fluid from the reservoir and replace with a quart of MMO.

Clicking noises completely gone and no more jacks "settling" either. My whole hydraulic system is working the best it has since I got this coach in late '12.

Boowho??

AFAIK, there is only ONE MMO. It's been around since around 1928, basically UNCHANGED in that time. It's an extremely general purpose type of lubricant. Should be available at any of the big box automotive parts stores.

Around $5-6 for a quart.

As far as where I've been...... just bigger fish to fry, I guess.

Currently at Yosemite and have been asked to do a work camper gig for the next 90 days.

Probably going to do it, since I've spent a about $4K on "toys" recently (most of it NOT MH related.... new shotgun, things like that) so could use a free spot for 2-3 months.

Thanks for asking.

Boowho??

That's what has me confused. I was told last year to add something to the Hyd system but I forgot what it was. Most people that tried it said it didn't help. This MMO has me interested.

Boowho, what noise were they making was it a loud click or banging. When ours retract they make a banging noise right before they stop. I did notice I was low about a quart in the res. when they were retracted. So I filled it up for now we will see how things work, I did buy a quart of MMO from Pep Boys. On our 2013 Berk I do know there is a recall on the jack pads. When ours was new we lost all for Pads on our maiden trip. I didn't know it til we spent a night in a truck stop in North NV., when I pulled the jacks up in the morning I heard a metal clank noise as they stopped. So Pulled forward a got out an looked on the ground and there was a jack pad, picked it up threw it in the bay and looked at the others and they were long gone. We got back home a few weeks later and it went in to the shop and the service people said there is a un announced recall on the ones we had.
