I personally prefer a top of the line Mobil 1 Synthetic over Yamahalube. Yamaha doesn't make oil. There have been MANY discussions on the topic of oil on this and other forums over the years. I lean towards
this end:
"It just drives me crazy when people get on " this oil does this and that oil does that" Kick!!!!!! Heres the real deal on YAMALUBE!!!!!!! If you guys want to STILL BE IN DENIAL,,,, PLEASE don't read this post!!!!!!!1st... Yamalube is made by CITGO (cities services oil company).. The packaging facility is on 39th and cicero in Chicago ( a few miles from my home)....2nd,,, Yamalube comes from the EXACT SAME ZILLION GALLON TANK AS DOES at least a DOXEN other brands of 2 stroke oil.... 3rd.. Yamaha does NOT have an oil refining or packaging company , 4th Yamaha buys their oil from the LOWEST BIDDER... They come up with a specification such as TC-W or JASO and the oil MANUFACTURING companies meet their specifications and submit their bids to YAMAHA.... YAMAHA in turn, contracts the LOWEST BIDDER in the demographic area that they market the oil in.... If you live anywhere near CHICAGO,,,The YAMALUBE comes from a zillion gallon VAT on 39th and cicero..... You could buy K mart or wal mart or farm and fleet 2 stroke oil and get the EXACT SAME OIL that is in the Yamalube bottle for HALF THE PRICE... Yamaha doesn't open up the caps and THROW ANY MAGIC POWDER in the gallons of oil when they come from citgo.... Sometimes they come directly from citgo and the yamaha warehouse NEVER EVEN SEE the cases!!!!! I know first hand because a friend of mine who WORKED for CITGO for 25 years used to bring me botles of TEXACO 2 stroke oil..... YES TEXACO 2 stroke oil and you know what???? He got it from CITGO where he worked!!!!!! and furthermore, citgo doesn't open up the bottles and throw the MAJUC POWDER FROM THE YAMAHA CHEMICAL PLANT to make YAMALUBE work better...... Heres another little TIDBIT for you guys,,,,,, The next time you go to pep boys or auto zone or murrays aoto,,, look and see just how many different kinds of ANTI FREEZE there are...... ARE YOU READY FOR THIS ONE???????????? THERE'S ONLY 2 COMPANIES IN AMERICA THAT MAKE ETHYLENE GLYCOL ANTI FREEZE.......... 20 brands,,,,,,,20 COMPANIES!!!!! BOTTOM LINE,,, MY VIPERS (2) and my sxr all use KLOTZ,,, My power valves are clean... My girlfriend has a viper,, her powervalves ALWAYS DIRTY!!!!!1 she drives my sled,,,, DIRTY POWERVALVES.... SHE drives a snowmobile like a FARM TRACTOR.. I drive a sled like I stole it!!!!! With MY SLEDS,,,,,, It's not about the oil!!!!!!! I use KLOTZ!!!! FAR superior to ANYTHING CITGO MAKES!!!!! there you have it!!!!"
Your perspective may differ. I buy it at Walmart in the 5 Quart jugs......my mechanic neighbor says Walmart has the best pricing on oil. I go to Advance Auto for plugs and filters.
