it might not void the warrenty all together but if there is something wrong with your engine and it should be under warrenty and they find out that your not using yamalube then they will charge you im almost positive or at least thats the way it is for snowmobiles... and how would it be illigal they are their own company they can make whatever rules they want

 

i run my banshee on klots i used to use yamalube untill one of my friends told me about klots i tried it once and i love it

 

i also run my shee on klotz and have never had any problems. i think it's the best

 

i really dont think there a difference with yamalube.

 

It comes down to this. If you are sure about another oil, and are a capable mechanic than use it. If in doubt, yamalube is the safe way to go. You just better be sure you're getting good info, perhaps from an engine builder or mechanic. At least thats how I play it. My kid's LT80 motor was done over by a guy who knows that motor inside and out. He said use Torco GP7, thats what I use. On the new Blaster we use Yamalube till we find a reliable recommendation.

 

I just bought a 1990 Yfm 250 Moto 4 for 1,000, Its a 4 stroke, what kind of Motor oil should i use? Weight? Brand?
Thanks alot for ur input.

 

So, nobody really KNOWS what could possibly be in Yamalube that is "better"? Wow, that's a shocker. With the brand loyalty of the Yamaha guys, you'd think somebody would know.

Oh yeah, 'better safe than sorry' isn't an answer either. Playing it safe isn't going to get you into the winner's circle.

But, thanks.

 

As far as 2 stroke oil goes, I used to use BelRay MC1 in my quadracer and it gummed up the powervalve to where it wouldn't operate. I switched to the Yamalube 2R and it stays clean and works. The 4 stroke oil I couldn't tell you anything except it's way expensive.

 

Here's the truth guys... There is NOTHING in Yamalube that makes it any better than any other 30 weight oil on the market. When deciding what oil to use, the main rule is to stay away from synthetic additives. The reason being that these synthetics actually make your oil too slick for a wet clutch and can cause your clutch plates to slip. Other than that, any thirty weight oil is fine. I use a fourty weight oil in my 686. I run in some very extreme temperatures and prefer the extra protection of the the fourty weight. However, I would have no quarems about running a thirty weight.

RedBullGotWings,

Federal law states that no manufacturer can void your warranty on any product sold in the United States for not using a subsequent product of the same manufacturer required as part of a normal maintenance schedule unless they provide it free of charge. This means that they cannot void your warranty for not using their maintenance products unless they are willing to provide them to you for free.
