Basically, M3Post theory of thinner oil = more oil where needed to help mediate rod bearing issue aside, will the thinner oil result in less wear/tear on motor and longevity due to better efficiency (as seen in MPG), or is this greater efficiency resulting in thinner oil thus creating MORE friction among moving parts??
Sorry, I don't know much about motor engineering and I'm beating a dead horse at this point, just wondering if my wonders are answerable or irrelevant (Seems like the latter)  |
I saw no such MPG change when I switched
