Need help with hm oils

[ka9mnx]

The MMO is burning off like others have said. Do not use!

I would use Mobil1 HM 10w-30. It's a "thick" oil. Works well in my old rigs.

Mobil1 HM 10w-30 API SN ACEA A3
Vi@40C - 78
Vi@100C - 12.1
HTHS - 3.5
VI - 149
NOAK - not published but guessing at @10
TBN - not published but guessing at @9

If you are adding a qt every 1500 miles, you are changing your oil a little at a time.
Just change the filter every 5-6000 miles depending on how good a filter you use.

I see no reason in your case not to move to a 10w40 and see what happens.
Following the OLM on early model Equinox proved for many to be foolish.
My wife had one, UOA's were always full of fuel. That was one car that needed a shorter OCI.

Now this is "heavy" oil!

Mobil1 HM 10w-40 API SN ACEA A3
Vi@40C - 107
Vi@100C - 16
HTHS - 3.9
VI - 160

First thing I'd check is the PCV system ... Next I'd go to a straight SAE 30 HD for one change and see if that made any difference. No VII's, just oil.

If that made a difference I'd come back and post about it. We can go from there.

An HM oil might help with leaky valve seals? But it might not ...

Need more info ...

no puff on start up. I have a feeling the mmo and fuel dilution is making this oci terrible. Im changing it today and will see what happens

I'd start here too.

Castrol Edge Titanium HM is one of the thicker syn HM oils.

 

[ka9mnx]

I went to the Castrol web site since I'm not familiar with their products. It's actually an average spec (10w-30) HM oil. Not thicker.

API SN, ILSAC GF5, ACEA A1 (old spec)
Vi@49C - 71.5
Vi@100C - 11.5
HTHS - 3.2
VI - 151
NOAK - 8.5
TBN - ?

I would use a 10W30 or 5W40 HDEO and monitor for consumption changes.

 

[dave1251]

Even a 15W40 will be suitable depending on where you live in Washington.

My choices where pphm, red bottle maxlife blend. Qs defy hm syn. Currently using pp with 1qt of mmo as a top off. I have about 1k left on the oci. I wanted to do 3k oci and a oil filter change every other Oci. What do u think to slow down consumption? Also has no leaks and it has 111k miles. The gm lea motor is a know oil drinker. Its also di so the oil always smells like fuel.


My Durango is a 2011 5.7L Hemi with close to 140k miles on the clock. The only two oils I have not had oil consumption with are QSUD and PPHM. It took more than 1 oil change after switching to get it to stop. Castrol Edge High Milage worked for my In-Laws 1998 Honday Odyssey with close to 160K miles. I would pick one of thoes 3 and try it for 3 or so oil changes.

I wanted to update that my brother took his Equinox to the dealer to get the oil changed again and they said it had a lot of metal in the oil and couldnt recommend driving further. He wanted to get a new 2017 Equinox (with the same engine I believe), and I talked him out of it. He's coming home in a 2017 Escape with the 1.5l Ecoboost now. I really hope this treats him well as the Equinox put him in a really bad spot.
