I have some Mobile I 75-90W motorcycle gear lube from a previous bike. I intend to change the final drive lube on my 98 Goldwing and use this lube. However, the manual specifies straight 80W. Anyone know any reason I should not use the Mobile I 75-90W? Thanks

... Howdy ... Alarms ... I Doubt If Any Harm Would Come Out Of Using The Mobile ... You 'might' Loose A Very Small Amount Of Mpg. With The Heavier G-oil ... Happy Trails ...

No problem, I used it in my 98SE
