No, it is not. Yet, it is for a turbo car. Plus, it does not say not to race the car... and proof? Any oil pressure sensor will detect it (sudden pressure drops, right?).The rotella isn't a track or drag strip formulation, it's generally for diesels and heavy duty use. People that do track or drag times or heavy slalom etc etc - should have a race oil ready that doesn't have any "foaming issues". I'd like to see the PROOF of foaming they claim is occurring
I know what you are saying, but understand that. Like I said. There were comparisons, and none really revealed anything spectacular. However, KIA did their own research and created TSB to advice not to use non-OEM filters.If your Kias were as sensitive to oil filter issues (non OEM vs OEM) as you mentioned, then certainly disassembling an OEM Filter to compare with aftermarket would reveal differences in construction, springs, valves, filter material, flow, gaskets etc.
I use OEM now and that's it. They are inexpensive anyway.
As for oils. I look into specs (viscosity, pour point, NOACK, shearing if available from manufacturer). Any good oil test requires extensive knowledge, plus equipment that is not only expensive, but not readily available. We are not "experts". I am no expert. But we share our experiences. We communicate what we see, what we feel, what we think is happening. Some listen and share their thoughts, some complain and argue...
