Which is the best grade of Yamalube 4 tranny oil should I use in my 2000 model Yamaha Blaster? Which would perform the best and be the best protection? The quad runs like a new one, sounds like a new one, performs like a new one, and looks like a new one and I would like to keep it that way. What have you used and what was the best.[img]i/expressions/face-icon-small-smile.gif[/img]

 

Yamalube 4R

 

Should I use Yamalube 4 10w30, 20w40, 20w50, and so on.[img]i/expressions/face-icon-small-confused.gif[/img]

 

Yamalube 4R is the semi-synthetic Racing oil (10-50) It wourks great I use it in my YFZ and R-1 track bike.
(There is only one kind of 4R).

 

I read a 1999 Yamaha Blaster owners manual and it said Yamalube 4 10w30.

I am not sure they have the 4r here or 10w50.

 

There is nothing wrong with the yamalube 4 10w30. You where asking about what people thought was the best, and the 4R is a step up. it coats the gears a little better, and allows for smother shifting etc. It is just a step up from the standard Yamalube. You won't have a problem either way.

The 4R will run you about $7/qrt
The yamalube 10w30 will run about $3.50/qrt

 

yfzn,,,i use the same oil..do u use it in the winter time too?

 

IM in Southern CA, there is no winter. So I don't know how it would work in the colder temps.

 

Thanks for the info. I to live in a cold climate and was wondering the same thing.

By the way it must be great to live in a warm place all the time.[img]i/expressions/face-icon-small-tongue.gif[/img]

 

I run nothing but Motul 20/10W-40 oil with a K&N oil filter and have had nothing but great performance and shifting from my Raptor and excellent clutch hookup! Best part is, I beat on my 2001 Raptor and the tranny is holding up fine with that setup and smells wicked too! It's a semi-synthetic blend and works great winter or summer!
