AMSOIL 10W-40 Metric Fully Synthetic Engine Oil (MCF)

AMSOIL 10W-40 Metric is a fully synthetic, high-performance engine and transmission lubricant designed for four-stroke metric motorcycles. It’s built to reduce friction, heat and wear, deliver smooth, confident shifts with positive wet-clutch engagement, maintain viscosity under high-temperature riding, and help keep critical components clean for reliable performance.

Key Benefits

• Reduces friction, heat and wear for premium wear protection

• Helps keep engines and transmissions running cool under heavy load and high rpm

• Contains no friction modifiers to promote smooth shifting and positive clutch engagement

• Engineered to control heat and prevent slippage and glazing to promote long clutch life

• Advanced anti-foam additives help prevent foam for reliable wear protection

• Anti-corrosion agents help provide protection during storage and long periods of inactivity

Applications (Specifications / Approvals)

Use in BMW, Can-Am, Honda, Kawasaki, Suzuki, Triumph, Yamaha and other motorcycles that require 10W-40 motorcycle oil.

  Not recommended for applications requiring an API GL-4 or GL-5 gear oil.

Change / Drain Interval (Service Life)

• Use with an AMSOIL oil filter for up to twice the motorcycle manufacturer-recommended change interval (miles/hours) or 1 year, whichever comes first.

• When using any other oil filter, change the oil and filter at the recommended intervals.

• Extended drain intervals are not recommended in racing or modified engines; oil changes are at the owner’s discretion.
