Just took my HiHy in for its 5K routine maintenance. I provided the 5W30 synthetic oil (Mobile One) since they charge an arm and leg for the synthetic oil (2yr /24K Dealer maintenance plan). They told me that Totoya is now specifying 5W20 - although my Oil cap and manuals state "SAE 5W30".
So for those of you in the same boat - check it out. I would think that Toyota should notify registered owners of a change in their recommendations. How many Jiffy Lubes, etc whould know this? And why the change?
Seadog....
