Question: Is an oil's HTHS specification the MAIN one relevant to the MOFT it can provide? And.. then, how is measured MOFT?
HTHS = High Temperature High Shear... This is the specification I personally look at the most since it's probably the most accurate of how the oil is doing in your engine when it's up to speed running on the highway, or really anywhere once fully warmed up. The HTHS spec will determine the second half of the API specification for the grade of oil.. the first number is the W or winter number.
MOFT = Minimum Oil Film Thickness.
Questions:
1. Can MOFT be measured like HTHS? This again partially the basis for this question.. Not the same thing, are they?
2. Is KV100 a better metric for MOFT?
3. Is there any particular characteristic more suited to determine MOFT than HTHS? Does base oil moreso than the fully formulated package (which includes base oil) have some kind of more relevance to this? This again is what I'm hoping to open up to discussion.
Thank you!
