It’s quite simple: tte differences are small enough not to matter for most people, but if forced to choose, I discriminate. I can split the tiniest hair.and then :
so you claim first that for 1 5000mile oci even a group 3 will get the job done and dont have a significant difference with todays PAO based oils but later you hype for the superb base oil blend that includes PAO of esp 0-30 and critise the cheaper base oil of 5-30.
the you also say:
but you will choose a c3 oil bcs :
contradict again.so the conclusion is ,by your words that for a 5000 miles oci not any 5w-30 or 0w40 or 5w40 is the same.
so you agree with me!
So while I prefer ESP, the ability the prove it better empirically is beyond practical consideration. It’s philosophical.
I’m not sure why this is so confusing.
