BX2360 engine oil type

[Charliebrn]

Any oil experts on here? I finally ran out of my stock of engine oil that I’ve been using. I went to buy new oil and all the oil around here is CK-4. Since all the fuel I can buy around here is the low sulfur type, can I use the CK? The manual says only up to CG-4.

And yea, I’ve also only used 10w-30, but all ears….

I am NOT an oil expert.

But per the American Petroleum Institute (API), the CG4 spec is obsolete. API specs CH4, CJ4, CI4, and CK4 are current. Specs CH4, CJ4, and CI4 can be used in lieu of CG4. CK4 is not listed as either compatible or as exceeding the performance criteria. Not sure why.

IMO, CK4 would also be ok since its ultra low sulfur fuels is all that is available in the U.S.
