Hi Everyone ! Last weekend my oil seal started leaking from the final drive I understand that more than few of You dealt with this problem. Bike is still under waranty and im using mobil 1 oil for the gear Question I have is since its not yamalube do You thing the dealer might give me some bs about its not recomended oil and refuse to cover this repair?
As others above have mentioned, I too use Mobil 1 75w90 LS synthetic, and no leaks after over 35,000 miles. I did start with Yamalube's gear oil until around 6,000 miles (IIRC), then made the switch. I always tend to start with OEM lubes for the first few thousand miles, then switch to Mobil 1 lubes.
As for the dealer... No, he should not give you any trouble if a seal needs to be replaced under warranty, and for a couple of reasons. One, Mobil 1 gear lube meets or exceeds the lubrication specs as shown in both the owners and service manual. As long as you are using lubricants that meet or exceed the manufacturer's recommendations there shouldn't be any issue.
Second, you are protected, by law, by the Magnuson-Moss Act (
http://en.wikipedia.org/wiki/Magnuson%E2%80%93Moss_Warranty_Act,
http://www.mlmlaw.com/library/guides/ftc/warranties/undermag.htm, and
http://lmgtfy.com/?q=magnuson+moss+warranty+act for more info). Under Magnuson-Moss it is the responsibility of the manufacturer to prove that your use of the lubricant in question was directly responsible for any damage or failure, and again, since Mobil 1's products meet or exceed the manufacturer's written recommendations, etc. it would be hard for them to prove that the use of Mobil 1 gear lube would have caused a final drive seal failure any sooner than the use of Yamalube's own branded products. Remember, Yamaha does not manufacture Yamalube products, but instead farms those out to lubrication producers around the world... In fact, some Yamalube lubricants may have similar or identical labels and descriptions, yet be made by entirely different oil producers and have completely different chemical make-up from country to country.
Don't let your use of Mobil 1 worry you in the slightest. In fact, I doubt the dealer will even ask you, and if he does the instant you say "Mobil 1" any other discussion of lubricant will cease.
Hope this helps!
