How to Read the Chart

Each row compares AMSOIL’s product line with the most similar competitor oils in both viscosity and intended use. For instance:

Signature Series aligns with the highest-end synthetics like Mobil 1 Extended Performance or Castrol Edge.
OE Series matches standard synthetics meant for factory-recommended drain intervals.
Max-Duty Diesel Oils are heavy-duty products similar to Mobil Delvac or Valvoline Premium Blue.
Specialty oils, such as Z-Rod and Marine Synthetic, correspond to niche applications like vintage or water-cooled engines.

This makes switching between brands easy while ensuring you maintain equal or better protection.

Benefits of Using AMSOIL

Longer drain intervals: Up to 25,000 miles or 1 year for Signature Series.
Superior wear protection: Reduces metal-to-metal contact and friction.
Excellent temperature stability: Performs well in both extreme heat and cold.
Cleaner engines: Advanced detergents minimize sludge and carbon buildup.
Fuel efficiency: Low-friction synthetic base oils improve mileage.
Versatility: Wide product range for gasoline, diesel, racing, marine, and industrial use.
