AMSOIL Industrial Straight-Grade Diesel Oil is a conventional SAE 40 oil formulated to protect against wear, deposits, acids and oil consumption in older diesel and gasoline engines that require a straight-grade oil. It helps maintain engine cleanliness and efficiency to help reduce maintenance.

• Resists engine wear to help maintain compression and horsepower while reducing maintenance.
• Helps reduce oil consumption, reducing the need for frequent top-offs.
• Resists harmful deposits, sludge and acids to maintain engine cleanliness while promoting long component life.
• Suitable for diesel and gasoline engines that require an SAE 40 oil, consolidating inventory.

RESISTS WEAR

• Formulated to prevent wear to piston rings, cylinders, bearings and other critical components for long engine life.
• Helps maintain engine compression for maximum power and service life.

INHIBITS OIL CONSUMPTION

• Resists volatility (burn off) in the presence of elevated heat, reducing oil consumption.
• Reduces the need to frequently top-off the engine between oil changes, decreasing maintenance and costs.
• Inhibits oxidation and helps prevent harmful sludge and deposits for maximum cleanliness and long life.
