I don't think so, as their used for commercial vehicles.
I'm not sure how to find out (for sure) but; the containers (markings) havn't changed and would have, if the oil had.
We all may need to find an additive; if this "global warming" farse continues.
Another thing here is the spring pressures. These new (import) lifters aren't designed for them & 'hollow out' pretty fast. Then the cam goes, right after.
It's NOT all the oil's fault as mentioned. In the "old days" we just changed out the lifters before that happened.
Happy trails.
