I like your 10w-30 idea ðŸ‘ðŸ»
Did you stay with Yamaha branded oil because of mechanic suggestion or BITOG feedback?
Used Yamalube mainly because I wanted to have an FC-W approved oil in there, and not sure that non-FCW oils have the combo of high HTHS and anti-corrosion stuff. Probably wouldn't matter, but . . . .
Currently running Amsoil marine 10w30 (no creeping up dipstick so far), and have Amsoil marine 10w40 lined for next oil change in a few months. Curious to see if it changes anything. I'm glad that I've finally been able to stop the oil from creeping up the dipstick, just not sure if it was the injectors or the oil.
Mine didn't make any oil for first 600-700 hours, then started making oil after I switched from Yamalube dino 10w30 to Yamalube synthetic 5w30. Now have finally stopped the creeping up the dipstick. Funny that the Amsoil is actually cheaper than the Yamalube dino. Will post when I have data on these different oils.
