Has anyone used this oil in their Rover?


I have a lifter that "ticks" and comes and goes at times. 99K miles.


Truck is driven in the summer / fall only.


Spotted the oil at the auto parts store, but the parts Mgr. said it was not friendly to CO2 sensors?


Can't believe that Diesel Engine Oil would be ether, but some run the Shell oil, Rotella I believe, 15w40.


Thanks...

 

I personally wouldn't use anything that heavy. I used to run Rotella, after my rebuild I started running 15w40 Royal Purple. That's about as heavy as I would go, but that's just me.

Sometimes you can cure a clicking lifter by running a bottle of sea foam or half a quart of ATF in your oil for ~500 miles, then doing a fresh change with new oil and filter. If that doesn't change it then I would either just let it tick on or, if it really bothers you, swap some new lifters.

 

Have you had to do head gaskets yet? If not then I would just swap the lifters whenever yours go.

 

Thank you both and I agree with each of you.


15w-40 is heavy enough and if I do tear it apart, will replace the lifters and check those rocker arms.


Thanks, just wanted to ask for an opinion...


Thanks again.......

 

we usded Marvel Mystery Oil form a short while changed to Rotella 15w-40. We still have the #ticking. Would #seafoam or #atf work better than #MMO? After that I would assume if we still have the ticking we would do the lifters. Yes? No?

 

how hard is changing lifters?

 

Almost as bad as doing head gaskets. The only thing is you don't have to remove the heads

 

I've never personally used ATF in an engine, but I've used seafoam on multiple occasions. Always seems to do a really good job cleaning crud out. I usually put half a bottle and run it 500 miles. If you're not already, I'd use an oversize oil filter of a quality brand. Mobil 1 M1-301 (I think) or Wix 51515XP (definitely). I personally prefer the Mobil filter.

It's a full day job. Maybe two depending on how familiar you are with tearing down the top of the engine. Like Jay said, about the same as doing head gaskets. The only difference would be that you don't have to remove the heads, spark plugs, and exhaust manifolds. If I'm that far in I'm replacing head gaskets at the same time unless they've been done recently. Probably my cam, too, and read up on proper break in procedure.

 

I used to run straight 30W in the summer when it was hot.
These engines are loose.

If you got a tick, keep changing the oil.
Probably dirt in the lifter.

 

our biggest problem is that our Discover isn't smoggable yet. We were told by the mechanic it has a low compression in one of the cylinders so that why the assumption of a stuck lifter, plus the ticking. Since it's not smoggable yet we can't get it registered to drive it around, legally. So we are just running it around our neighborhood. So getting miles on it to clean out the engine is difficult.

We we also have an exhaust leak so we are looking at a pile of issues to solve.
