AMSOIL HEAVY-DUTY SYNTHETIC DIESEL OIL 5W-40

Maximum Engine Protection:
Wear on rings and cylinder liners leads to increased oil consumption and loss of compression, resulting in reduced horsepower and fuel economy. Independent testing shows AMSOIL Heavy-Duty Synthetic Diesel Oil delivers increased wear protection, delivering the security of providing diesel engines the extra protection they deserve.

Viscosity Control:
Using top-tier synthetic base oils, AMSOIL Heavy-Duty Synthetic Diesel Oil is naturally resistant to oxidation and the thickening effects of soot contamination. That, along with boosted detergent/dispersant additives, keeps soot particles suspended independently, helping prevent the formation of larger, wear-causing particles. Viscosity increase is minimized and soot-related wear is controlled. Lower volatility also helps AMSOIL Heavy-Duty Synthetic Diesel Oil retain its viscosity after high-temperature service for maximum engine protection and efficiency.

Excels in Extreme Temperature:

AMSOIL Heavy-Duty Synthetic Diesel Oil resists thermal (heat) breakdown better than conventional and competing synthetic diesel oils. Unlike conventional oils, Signature Series contains no wax, staying fluid in sub-zero temperatures for easier starting, improved oil flow and reduced wear.

Minimizes Oil Consumption:
AMSOIL Heavy-Duty Synthetic Diesel Oil has a low rate of volatility (burn-off), reducing oil consumption during operation and passing less oil vapor into the combustion chamber. It provides up to 66 percent less oil consumption than required by the API CK-4 standard in the Caterpillar-1N oil consumption test.
