MQTpR OIL 



for Trattor, Truck or Car 



Keeps Resinous Formation ot 

 a Minimum 



Hot oil oxidizes (breolct down), ani 

 forms sticky vornish or lacquer de- 

 posits on hot ports of the engine 

 such OS piston skirts ond rings. Spe- 

 cial additives in lllini oil keep this 

 oxidation to o minimum. 



Keeps a Clean Motor Cleon Longer 



\ \\\iiii//^ /. 



Oxidized oil (resins or "varnish") 

 forms a base which collects insoluble 

 combustion products and causes a 

 dirty engine, lllini motor oil, being 

 highly resistant to oxidation, greatly 

 reduces the possibility for an ac- 

 cumulation of combustion products, 

 lllini keeps o cleon motor clean 

 longer. 



Provides Better Piston Seol 



Piston deposits directly interfere with 

 good engine performance. Deposits 

 in the ring zone cause sticking rings 

 — resulting in rapid wear and loss 

 of power, lllini motor oil fights pis- 

 ton deposits, lllini "stands up" under 

 heat, is relatively nonvolatile, hos a 

 high viscosity index. 



Prevents Bearing Corrosion 



High heat mokes many oils corrosive 

 to bearing metals. This corrosion may 

 result in bearing failures, lllini motor 

 oil gives protection against bearing 

 corrosion. In fact, lllini motor oil 

 gives complete motor protection. 



Gives Longer Life to Rings 

 Cylinder Walls 



lllini provides more than ample film 

 strength to take the heoviest bearing 

 pressures and strongest piston side 

 thrust your tractor, cor or truck con 

 build up. lllini is refined from the 

 finest paraffin crude oils by the most 

 modern methods, and reinforced 

 with superior additives for the best 

 in performance.
