See the Product Data Bulletin for full details.
FIGHTS ENGINE WEAR
- 75 percent more engine protection against horsepower loss and wear1 than required by the industry standard, extending the life of vital components like pistons and cams.
- Develops a strong fluid film that keeps metal surfaces separated.
- Robust anti-wear additives further reduce wear in metal-to-metal contact regions for maximum engine life.
1Based on independent testing of AMSOIL Signature Series 0W-20, in ASTM D6891 as required by the API SN specification.
Utilizing top-tier synthetic base oils, AMSOIL Signature Series SAE 5W-20 is naturally resistant to the oxidation and the thickening impacts of soot contamination. That, along with improved detergent/dispersant additives keeps soot particles suspended individually. Helping prevent the development of greater, wear-causing particles. Vyscocity increase is minimized, only increasing by 0.1% in standard tests. Even with double length tests, SAE 5W-20 delivered twice the vyscocity control required by standards. Also, soot-related wear is controlled. Lower volatility also helps Signature Series SAE 5W-20 retain its vyscocity after high-temperature service for max engine protection as well as efficiency.
CLEAN ENGINES FOR OPTIMAL PERFORMANCE
- Formulated with superior thermal durability that resists breakdown and keeps pistons clean.
- Controls heat and minimizes performance-robbing deposits.
- Maximizes engine life and performance.
Helps Keep Engines Cleaner
Signature Series is fortified with a heavy treatment of detergent additives, delivering 28 percent more acid-neutralizing power than Mobil 1* and helping engines stay cleaner, longer.LL

AMSOIL Signature Series SAE 5W-20 is compatible with other conventional and synthetic engine oils. Mixing AMSOIL diesel oils with other oils, though, will shorten the oil’s life expectancy and decrease the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
- Aftermarket oil additives are not recommended for use with AMSOIL synthetic diesel oils.
Normal Service – Up to 25,000 miles (40,200 km), 700 hours of operation or one year, whichever comes first, in personal vehicles not operating under severe service.
Severe Service – Up to 15,000 miles (24,140 km), 700 hours of operation or one year, whichever comes first. Severe service conditions include commercial or fleet vehicles; excessive idling; or frequent towing, hauling, plowing or driving in dusty conditions.
- Modified engines (non-stock), racing vehicles and vehicles using alternative fuels (E85, CNG, propane, etc.) are excluded from extended drain interval recommendations.
- Change at the vehicle manufacturer’s recommended drain interval outside U.S. and Canada.
- AMSOIL Oil Filters are designed for extended drain intervals. Do not exceed 12,000 miles (19,312 km) or one year with other brand filters unless longer intervals are recommended by the vehicle manufacturer. Always change filter when changing oil.
- Check oil regularly to maintain proper fill levels.
AMSOIL Oil Filters stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL Oil Filters.
