SAE 5W-30 Motor Oil (ASL) & SAE 10W-30 Motor Oil (ATM)
Dramatically outperforms conventional petroleum motor oils. Reduces friction, heat and wear for maximum power, performance and fuel efficiency. Resists high temperature burn-off, chemical breakdown and sludging to keep engines cleaner. Outstanding low temperature fluidity for fast, dependable winter starts and immediate start-up protection. Exceeds the most demanding world-wide performance standards and meets warranty requirements for all domestic and imported passenger car engines, both turbocharged and non-turbocharged. Up to 25,000-mile or 1-year drain intervals.
SAE 0W-20 Motor Oil (ASM)
This is AMSOIL’s newest synthetic motor oil that is recommended for applications requiring 5W-20 and 0W-20
SAE 10W-40 Motor Oil (AMO) & SAE 20W-50 Motor Oil (ARO)
Ideal for cars, hot rods, motor homes, motorcycles, gasoline engines, diesel engines and other applications that require or benefit from higher viscosity oil.
Synthetic XL 5W-30 (XLF), XL 5W-20 (XLM), XL 10W-30 (XLT) & XL 10W-40 (SLO) Motor Oils
AMSOIL XL Synthetic Motor Oils provide peace of mind. The oil drain interval recommendations for many of today’s vehicles extend well beyond the traditional 3,000-mile interval, some up to 12,000 miles with electronic oil monitoring systems. Unlike petroleum oils that have 3,000-mile maximum recommendations, AMSOIL XL Oil provide 7,500-mile/six-month drain intervals or longer where stated by vehicle manufacturers or indicated by oil life monitoring systems. When using AMSOIL XL protection and performance are not sacrificed with longer drain intervals.
