The Story of a New Fuel 



FS/50 is a well balanced modern tractor fuel, incorporating the 

 economies and power-giving characteristics of earlier tractor fuels 

 and the smoothness and flexibility of gasolines. 



• WHERE TO USE IT! 



FS/50 may be used in any low compression tractor built to operate 

 f" on tractor fuel or distillate. It is not recommended for high com- 



. pression tractors. • 



• HOW TO USE IT! 



To obtain the maximum performance from FS/50, tractors must be 

 warmed up on gasoline, also medium hot to hot spark plugs should 

 be used. Manifold temperatures should be maintained by proper 

 adjustment of the manifold heat control valve. Radiator tem- 

 . peratiu^s should be maintained in accordance with instructions 

 outlined in the tractor manual for burning distillate. 



• WHAT ARE ITS ADVANTAGES? 



FS/50 tractor fuel will operate with more smoothness under varying 

 load conditions. This fuel will also react quicker to the governor 

 and will not "load up" so quickly during short periods of idling. 



• WHAT ARE ITS DISADVANTAGES? 



The fuel cost per acre farmed, may be slightly higher than that of 

 '; . the other types of tractor fuel. This additional cost is not great, 

 however, and will depend some upon the conditions under which 

 the tractor is operated. 



• IS IT TAXABLE? 



A State tax of 3c per gallon must be 

 paid by the operator at the time of 

 sale. A refund may be obtained, how- 

 ever, if the fuel is used for a non-tax- 

 able purpose. 



The Federal tax of IJ^ per gallon 

 must be paid by the operator, unless he 

 , signs an exemption certificate. Cer- 

 tificates are available from your deliv- 

 ery man. 



• WHERE CAN I GET IT? 



While some Service Companies still 

 prefer to stock the earlier (T-40) fuel, 

 most Service Companies are now hand- 

 ling the new FS/50. 



Your Blue Seal salesman will tell you 

 which fuel is currently available in your 

 area.
