I'm past due for service and my dealership doesn't cover this as part of their maintenance program. What is used for factory fill? The owner's manual only says they recommend GL-4 in 75W-80 viscosity with a blanket Castrol endorsement. I haven't been able to find Castrol GL-4 75W-80 (in the US) so I'm looking for alternatives.
I'm looking at Redline or Pentosin, but that's really the only to options I've been able to find that meet the GL-4 75W-80 requirements. Does anyone have any other recommendations or experience with these? I do get a bit of grind if I run 1st up to redline and try to shift to 2nd too quickly so I'm looking to fix that problem with the change.
