you can use pretty much any unleaded gas but it runs a little better on 89 octane , or higher but if you have a stock blaster you can run 87 octane
i have a 2002 Yamaha blaster and i use castrol 10w-30
As long as its Not a yz model blaster.
No, you can not use engine oil in place of two cycle oil.
yamalube is the best
i always use 32.1 mix in mine
10w 30 or 20
Use adhesion promoter from Duplicolor on the plastic, then choose your paint color!
My son has a 2005 Blaster set up for racing. We usesynthetic gear case oil. That's how its labled on the quart bottle on oil weight on it. Dont use regular car motor oil because it does not lub clutch correctly.
A Blaster is air cooled, not water cooled. no antifreeze.
Use NGK MOdel # d7ea WITH A GAP SIZE OF 0.028
I don't have a Yamaha blaster.... but I did a little search and found out that it is a two cycle engine. I'm sure that you realize that in a two cycle engine, you lubricate the engine through the oil that is added to the gas, and not through a traditional oil reservoir system. As far as what kind of oil you can add to the fuel to create the proper mix.... their are specially created oils for two cycle use. I know of one Yamaha two cycle oil that was used in a Yamaha scooter I had... it was called "yamalube" ... good luck!
10w-20
