When their 0W-16 oil specs for viscosity at 40C and 100C are compared to HPL's for the same oil grade, the Idemitsu shows numbers closer to being a 0W-12. Just sayin....
I would be concerned about wear numbers and potential loss of viscosity due to fuel dilution if that is correct, and normal...
Sounds like the owners of that place, probably the " investment firm " of Dewey, Cheatum and Howe, used the " Madoff method " of calibration on those pumps. IJS.......
I haven't noticed ANY difference in gas mileage using 5W-30 in place of the factory fill 0W-16 in a 2023 Toyota RAV4 LE that I used as a trade in for my current 2025 RAV4 XLE. I am currently using 5W-30 in my 2025. Both are non- hybrids and I have approximately 80K miles driving in the 2 vehicles.
That makes sense, especially when it can take 2 or 3 oil changes with a different brand of oil than previously used to get an accurate UOA after switching brands of engine oil.
I understand it now, with Valvoline Restore and Protect also having moly in their chemistry / product formula, whatever " magic molecules " they have found that is providing the " Protect " part very probably wouldn't interfere with the higher dose of moly in an oil, such as HPL or others.
So do you think that the " Protect " component / chemistry of this oil would inhibit the high dose of molbdenum in the HPL line of oils from actually performing the benefits that molybdenum provides to an engine ? I'm wondering if a barrier or coating is created by the Valvoline Restore and...
Errr...manipulate dyno results in the way that some NHRA racer did back in the 80s with a few ounces of nitro methane in the oil. 😲The pcv system recirculated it into the intake system. His competitors and the tech people couldn't figure out how he was always WAY faster than the class standard...
