Any Rotella Opinions? Heard a lot of good things, just wondering...
T-4 is not a full synthetic oil only part syn. T6 is the syn. But mainly, because I dont like full synthetic, I think it makes my top end rattle more in hot temperatures at least it did in my harley until I took it out. I dont like it in hot climates and I only ride about 2-3000 mi a year right now and dont want to waste money changing full syn oil when dino or part syn is as good or better when changed every 3000 miI can't argue with anything that you said.......except THIS.
What possible reason could you have for saying that ??
Look it up.I'm willing to listen as to WHY I would want to run synthetic and what possible benefits it could have for me.
I don't think you are making a valid comparison there.It may well be better for the Royal Star but for the Harley 103
in hot temps I got a lot more knocking running full synthetic oil than with reg dino or syn blend maybe thats what prejudiced me. I run straight Valvoline 20W50 motorcycle oil in it as I have for all my bikes.
