• 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 (20,000 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.
