CUTS MOTOR OPERATING EXPENSE 
FIVE WAYS 
1—SAVES CARBON CLEANING: Because of its ability to remove hard 
carbon from rings, pistons, valves and spark plugs, Naturalube 
minimizes carbon cleaning and valve grinding. 
2—SAVES WEAR: Naturalube’s protective oil film is a trustworthy 
guard against excessive friction wear because it is oiler, more pene- 
trative, and more adhesive. 
3—SAVES REPAIRS: Because of its stronger natural film, Naturalube 
offers a wide margin of safety which prevents costly repairs due to 
oil film failure. 
4—SAVES GASOLINE: Naturalube lowers gasoline consumption be- 
cause it lubricates better, reduces friction, and removes power-destroy- 
ing hard carbon from pistons, rings, valves, and spark plugs. 
5—SAVES IN OIL ADDITIONS: Because of its great resistance to 
vaporization and “oil breakdown” Naturalube will save you money by 
minimizing oil additions.
