      AMERIGUARD® Full Synthetic 5W-20 Motor Oil
Full Synthetic Motor Oil Passenger Car Motor Oil
AMERIGUARD® Full Synthetic 5W-20 uses the latest technology to deliver dependability, unsurpassed engine protection, performance, cleanliness, and fuel mileage. You and your vehicles work hard for the important things in life. Trust high-quality AMERIGUARD® Lubricants by Sapp Bros. to protect engines and your investment -- at an excellent value. Our motor oil is formulated to provide the following features and benefits:
- Controls friction and wear more than 80% better than the latest API requirements.
 - It is engineered to improve fuel mileage and to maximize horsepower and acceleration.
 - Longer and better engine protection than conventional oils due to strong and uniform synthetic base oils and advanced molecules that provide a strong film barrier to control friction, resist wear and keep metal surfaces from coming into contact.
 - Provides a strong oil film to avoid metal-to-metal contact, even under extreme stress and heat.
 - Stands up to heat and shearing, so it delivers long-lasting protection and control.
 
Applications
- Gasoline-fueled and flex-fuel passenger cars, light trucks, and sport utility vehicles, including gasoline-electric hybrids, especially when operating under severe conditions.
 - Formulated to protect turbochargers and emission control system catalysts.
 - Formulated for use in vehicles operating on ethanol-containing fuels up to E85.
