Rotella 0w40 no longer CJ-4/SN

[Snagglefoot]

Although not many folks in the south paid attention to this, Rotella 0w40 CJ-4 also had a SN rating. Shell Rotella took this away and the Rotella 0w40 is now CK-4 (and CJ-4) but no longer SN. The API will no longer give out a S rating to any oil with over 800 ppm phosphorus like it used to with some of HDEOs. The first two products are the old jugs. The last two are the new product. Enjoy.

I've never even seen this before. Only recently saw the T6 15w40 at Menards. Must be a northern flavor.

Good... don't need or want SN/SP

 

[Rygrego]

Who cares? If you know the content and like it, run it. I have not changed a thing since Rotella T6 5W40 and 15W40 lost the rating. The only issue ever would be if you burn a lot of oil , otherwise nothing is different. My Jeep and Chevy truck have lived on these oils for over 10 years and I'm not stopping because the stupid ratings have changed.

HDEOs are no longer allowed to be dual rated unless the comply with the API S-rating limits for phosphorous since rotella has something like 1100ppm of phosphorous it can no longer carry an S-rating.

In he US Advance Auto was carrying it but it recently got blown out for $5.95/gal since about the only people who buy it are old Volvo guys, some stores I went to still had the old style SOPUS jugs they stopped using around late 2015-2016 because nobody bought it.

Yep, come on up to High Level, Alberta and fire up your diesel when it’s - 40 and there’s no plug ins available.

Perhaps it's just me, but I didn't find this 0W-40 on Shell's website yesterday. Is it there?
This is/was great arctic oil for Alaska.

You can try this Fleet Maintenance website describing both the new Rotella T4 for Natural gas engines and the revised T6 0w40. The Shell website does not seem to be updated.

Shell Lubricants announces new multi-use engine oil, API CK-4 certification for existing cold weather engine oil

The company's new T4 NG Plus 15W-40 heavy-duty engine oil is formulated for use in natural gas, diesel, and gasoline engines.

I picked up 6 gallons at Advanced for 12.35 a gallon. I won't run it in my ram because it's not CK and it's new and under warranty but I'll run it in all my other stuff!

This is interesting and, slightly off topic but related. I recently cleaned out all local Autozones of their Chevron Delo 5w40 synthetic. It seems heavily marketed to diesel but carried the CJ/SM for the "LE" (discontinued) or CK4/SN ratings for the "XSP." In the fine print or info sheet it states it's also for gasoline and turbo engines. Autozone has clearanced them at only $7.50 per gallon.

But looking at a VOA I found online, the phos ppm seemed to be around or slightly above 800 ppm. I wonder if Chevron is doing away with the SN ratings entirely on these? I wonder if these truly are okay for gas engines?

Then again, looking at the Mobile 1 0W40 VOA I found online, the phos is 1020 if I'm reading that right. Looking at Pennzoil Platinum 5w40 it's also north of 800 on a VOA found here.

So is it the phos, or something else?

Phosphorus limits for SN are for grades 30 and below, no?

Exactly.

They are getting rid of the old practise of putting an SN on some xw40 HDEO’s. If it’s over 800 ppm phosphorus they can’t list SN any more.

With some difficulty I found a PDS that included TBN: 8.6. I was thinking about its’ usefulness for Canadians or northern tier USA states that make an annual trek to Mexico every winter; considering much Mexican diesel is still ~300 ppm.

Like this old Volvo red block guy.

So what if they can‘t get SN? Why not just SJ?

Am concerned without an S rating it won’t be suitable for neutralizing gasoline combustion byproducts.
