I suppose I HAVE TO JUMP IN ON THIS YAMALUBE THING!!!!!!! Yamalube is made by CITGO... (cities servics oil company).... Yamalube is NOTHING special compared to the DOZEN OR SO different bottles that CITGO uses to market their oil..... You could buy FARM AND FLEET 2 stroke oil and get the EXACT SAME THING AS YAMALUBE in a orange bottle instead of a black bottle for HALF THE PRICE!!!!!! Yamaha looks for an oil company that MEETS their tcw or jaso SPEC!!!!!! THE LOWEST BIDDER.... NOTHING ELSE BUT THE LOWEST BIDDER!!!!! If EXXON or BP will produce it for a dollar less than citgo would,,, You know what????? Yamaha probably would buy it from them!!!!!! Yamaha does not make OIL, NOR are they in the oil refining business!!!!!! ANY SYNTHETIC OIL IS FAR BETTER THAN YAMALUBE!!!!!! I knew a guy who would bring me gallons of TEXACO 2 stroke oil from the plant in Chicago (39th and Cicero).. it said TEXACO two stroke oil...... HE worked there for 25 years.. THE SAME TANK THAT FILLED THE YAMALUBE BOTTLES ALSO FILLED ALL THE OTHER BOTTLES WITH A DOZEN DIFFERENT LABELS!!!!!!! and YES,,, CITGO makes 2 stroke oil for its competitor TEXACO!!!!!!!! I've seen it with my own 2 eyes!!!!! I've used KLOTZ since the beginning of time (my time) and have had a wonderful experience with klotz..... KLOTZ makes KLOTZ!!!!! No one else,, nor do they put it in a yamalube bottle (thank god!!!) Gary Oles nosboy
