Anyone have any qualms using Royal Purple 75W-90 GL-5 full synthetic lower unit juice in a new F75?
After the breakin period, I want to put in the RP, as I have lots on hand.
Warranty issues not using Yamaha 90W hypoid oil?
For that matter...any warranty issues using synthetic engine oil in the proper weight?
Any actual warranty declines for using anything other than Yamaha branded parts/fluids?
