Oil change mileage??
 
Hi guys, just got a Kawasaki ninja 250 and was wondering what kind of fe gains have people gotten with reducing oil viscosity in their bikes??? I'm thinking of using amsoil 0w-20/30 with Lucas oil mixed in, I've had good success doing this in my cars with no issue!! What do you guys think??

Using non-motorcycle oil you'll gain clutch chatter and poor shifting. Based on how light that bike is, you're better off learning a better riding technique than increasing wear on your trans.

The problem comes from the engine and transmission sharing the same oil, so the oil is 'worked' harder than just oil used in an engine alone.

I am not saying you could not possibly get better FE from a change in viscosity, but you would have to monitor how much the engine and transmission are handling the change.

There is lots of research you could probably do, knowing that...

It said in the owners manual that my bike could use 10w-30, but I'll double check a few times before changing the oil!!!

Generally what I'm doing is taking the lower viscosity oil and adding Lucas to give it extra adhesion to the metal parts of the motor and clutch!! Like I said, I've been doing that in my Jeep Grand Cherokee for years with no increase in wear as far as the filters concerned!!

Get a lubricheck.
And always follow manufacturer lubricant specs.

Thanks a lot!! I was wondering how to check lubricity!!

The lubricheck checks TBN which is oil acidity.
Easy way to see if the additives that prevent a sluge build up and clean the engine are still working.

Ah, I see!

Rotella T6 5W-40 is on the thinner side of 40-grade, and does shear down close to a high 30-grade rather quickly.

Rotella T5 10W-30 semi-synthetic would also be a good choice if you wanted a cycle-safe 30.

My son run a 30 in his Ninja 250, and it spends most of it's time near redline.

That said, I don't think you are going to see any noticeable gains in performance or economy by going to a 30, but I think it's OK as long as you use a good one and keep track of the level. Ninja 250s will lose some oil into the airbox from the crankcase breather when running at high rpms.

I personally don't like oil additives, so I would skip that.
