They keep changing the formulas, which makes is hard for us to figure out what new oils are good or bad for our little bikes!

Dave,

I bought the new "Extreme temperature" T6 CK-4 oil a week ago or so in the Falcon (CO) WalMart. I assume it will be available in many other locations soon, if not already.

A few weeks ago I looked around in the local stores and truck stops in my area , and they did not have the new CK-4. That could change in the future.....and it makes you wonder if they will phase out the CJ-4? Is there really any reason to keep both.....as Shell states the CK-4 can be used in any engine requiring CJ-4.

Below are quotes from the Shell Webpages on T6. We need to remember that the bread and butter for the Rotella T is the diesel engine used in commercial vehicles......and if the formulations work for us - then we can benefit from all the research and development they have done. The big problem is that they are not designing this oil for use in wet clutch applications.....and they could modify the formula at any time in a way that would make the oil unsuitable for use in the Savage.

Selecting the proper Shell ROTELLA® engine oil for a truck or equipment will be easy. If it was built prior to 2016, whether it is on- or off-highway, choose CK-4 oil which directly replaces CJ-4 oils

The Shell ROTELLA® technology team has been working closely with Ford throughout the API category development process. We believe, and our testing demonstrates, that the new Shell ROTELLA® CK-4 formulations provide superior wear protection compared to Shell ROTELLA® legacy CJ-4 formulations.

Well, the pictures were mainly to reference the bottles of the different formulations regardless of oil weight (just a quick and dirty comparison) so please disregard the weight in the images.

Can you explicitly spell out for me where on the T6 container indicates whether it is the CK4 or the CJ4? Which is which?

Regardless of the flashy graphics on the front, you should be able to look at the back and see the specifications. See:

Formulating an oil (additive packs) is a compromise and is always changing. Different criteria are considered with each blending.
To get an idea of what is considered when blending an oil click on https://commercial.lubrizoladditives360.com/specifications/api/#API%20CK-4 and scroll to the bottom
You'll see that for the diesel oils that "fuel economy" is not important but if you were blending oil for an automobile that economy would be an important consideration.
We are interested in high zinc/phosphorous and also meeting JASO ... many good diesel oils meet this requirement if we choose the right blend.
Most auto oils DO NOT meet our ZDDP requirements as recent auto oils are limited to 800

There is lots of good API info out there if we do our homework
