What are you trying to improve on with that mix, in this engine with a 2000 mile OCI? What does Yamaha spec for an OCI? Run the 10w40 Dino and never look back. The scooter I believe has an 1800 mile OCI, why almost 2X as often as recommended?
well...I snagged the Amsoil from a local place that takes care of fire, ems, police vehicles on different occasions for slightly less than $4/qt to slightly more than $5/qt (some goofy billing quirk at the register in their firearms dept)...I got it so I might as well use it to 'beef up' whatever I use and make a synthetic blend; the V Star 250 is oil/filter every 3k & the Buddy 125 is every 1.8k for oil & every 3.6k for filter; I always change oil/filter early on 2 wheeled death machines...I do this to have a higher chance of keeping oil in proper viscosity range and clean out engine-transmission-clutch gunk sooner; my car never goes 5k intervals either; just who I am I guess

Did you even read the description? [Linked Image] Also to you VR1 recommendation again if you read it clearly states VR1 is not recommended for Wet Clutches. [Linked Image]
Myself and some others I know run Valvoline VR1 20-50 in wet clutch bikes with no problems....I believe it may not work in every bike and might be a matter of clutch lining material. Valvoline issues the warning to play it safe.[/quote]

Most of the high performance bikes have a clutch design that locks the plates tighter as the engine load/torque increases through the clutch.

I'm talking about older bikes with no centrifugal locking feature for the clutch plates...

*** UPDATE *** got tired of chasing my tail dealing with walmart online ordering to get more valvoline atv oil in 10w-40 to build a stash...orders not getting filled, cancellations not going thru, etc; just returned the original purchase to walmart and bought a gallon jug of supertech 15w-40 for $9.64...I'll add a few more jugs as pay checks allow

I doubt you would be able to tell any difference between the Valvoline and ST, aside for a few more bucks for gas.
