SAPS on a few motor oil options

[mathieu109]

Good evening,

I own a '21 eco diesel jeep. I am looking at my 5w40 options that meet the API SN (or SP) and MS-12991.

I am between a few:
Pennzoil Platinum Euro (super hard to find anywhere currently)
Quaker State Euro
Castrol Edge Euro Car

My question is this. I read that the Castrol has a 1.2 sulfate ash content. Are there any numbers for Sulfate ash in the other two I listed? Some people are running Motul 8100 and it has a Sulfate ash of 0.8%. If that is the spread between oils what am I looking at for SA on the QS and CE oils?

I am sure new to oils and different meanings and values so I appreciate any help and knowledge.

Would Havoline ProDS qualify? They have Euro oil like that, not sure of the certifications thou.

I have heard it does based on a list I found however I have no clue where to find it for sale. I tried some quick googles searches earlier to no avail. If you know any sources let me know and I will check it out to see what is what.

That saps and ash content become very important with oil consumption. Remember brand new engines can burn x amount of oil per thousand miles and be "acceptable" even though a new engine that burns an entire quart of oil or sometimes more per thousand miles like how some brands allow is basically a clunker in my eyes. But an engine needs to be able to do that and without the emissions failing during the warranty period.

But if no or very miniscule oil consumption the saps content in a dpf catalyst diesel doesn't really matter because the oil whose ability to deposit more ash than technically acceptable won't do so because it's not getting burned in the first place. So what's your oil consumption, that's what matters. And the manufacturer approvals as well. If it meets the required approval proper then there should be nothing to worry about. If it was my vehicle I'd use QS euro 5w-40 and call it a day. It's a great oil as i use it and be smart and change the oil frequently, these engines don't like extended intervals.

Thank you! I’ve only had the jeep a week so no clue on consumption yet. I plan to change every 5k on the nose. Do you consider the QS to brake down quickly or start out to thin? That’s the only complaints I’ve seen and just want to make sure I protect my engine. Especially being in hot Florida.

It can't break down quickly as it's approvals prove that it must resist break down and can't be too thin as it must have hths retention so although the starting viscosity is low looking it must retain it's viscosity which is the most important value. Someone on here posted a 6k mile UOA on a gas v6 Mercedes and it had a tbn of 7 and the starting tbn is 10 since it's an a3/b4 class oil. Diesel 5w-40's are thicker both in kv100 and hths but QS is in line with other euro 5w-40's and it's suspected of actually being very good against evaporative loss from high temperatures with the suspected noack score being 7%.

As mentioned their shouldn't be any concern with what you're planning since it shouldn't burn lot of oil. However, if you wanted to get ash down you could try to find a C3 40 grade oil, not a3/b4, which isn't very easy. C3 is easy to find in a 30 grade though. Any of those three should work just fine for many miles.
