2,000 HOURS PROVES BLUE SEAL SAFE 



Mr. Chester A. Ide, commissioner of Highways. 

 Bushnell Township. McDooough County, writes : 

 "We are now using the third drum of Blue Seal 

 Motor Oil in this Diesel "Forty" Caterpillar. 

 Since using Blue Seal we have noticed a decided 

 improvement in the compression of the Diesel 

 motor giving it added power. This traaor has 

 operated approximately 2,000 hours of hard 

 road work. We are highly pleased with the 

 restilts we have received from Blue Seal Motor 

 Oil." . 



Messrs. Cook and Frew (at right) oper- 

 ate this huge semi-trailer truck between 

 Lyndon, Illinois and Chicago. They haul 

 heavy loads of livestock to market and 

 make fast merchandise freight deliveries 

 on their return. Heavy loads, night and 

 day travel in all kinds of weather de- 

 mand the finest lubricating oil.

 safe and capable driver.
