1.4. PASSENGER CAR, STRAIGHT GRADE

 

PETRO-AMERICA, straight grade motor oil series is a single viscosity type commercial automotive oil designed to and intended for use in gasoline, liquid petroleum gas ( LPG ), and diesel engines. These oils provide significant improved control over engine deposits from low temperature sludging in severe stop and go gasoline engine service, as well as high temperature deposits in high speed, over-the road or off-highway diesel engine service. These oils are blended using stable, high quality base stocks and contain a balanced additive system containing an ashless dispersant, metallic detergent, rust inhibitor, anti-wear agents and defoamers. These oils have pour points and high viscosity indexes. These properties give good low temperature starting in the winter grades and insure prompt flow for fast circulation during the starting period. The detergent dispersant level assures adequate protection against high temperature deposits as well as ring and cylinder wear in diesel engines using fuels of moderate sulfur content up to 0.4%.

 

 

APPLICATION:

 

 

PETRO-AMERICA, straight grade motor oils are recommended for commercial fleets using gasoline, LPG, or diesel engines where manufacturers recommended an oil meeting MIL-L-46152B. They will give excellent performance when used for stationary and marine engines, both gasoline and diesel. In fleet service, they are recommended for door to door pick-up and delivery and over-the-road trucks, inter-and-intra-city buses, contractor equipment, utility fleets, taxi cabs, and passenger car fleets.
