AMSOIL: Heavy-Duty Synthetic Diesel Oil
Understanding Compatibility and Specifications
Can You Use Diesel Oil in Gasoline Engines?
Using diesel oil in gasoline engines depends on the oil’s specs and OEM guidelines. The American Petroleum Institute (API) classifies diesel oil with a “C” category (currently CK-4) and gasoline motor oil with an “S” category (currently SP). Diesel oil can be used in gasoline engines if it matches the required specs and viscosity for your engine. For example, if your gasoline engine needs a 5W-30 motor oil with API SN spec, a diesel oil with the same viscosity and spec is suitable. However, high-quality gasoline motor oil is usually the best choice for optimal performance and value.
Why Do Diesel Engines Need Special Oil?
Different Fuel Ignition Processes
Diesel engines compress air to high temperatures, igniting the fuel. Gasoline engines use spark plugs to ignite the fuel-air mix. These differences mean diesel oil handles higher engine temperatures, increased oxidation, and more soot. For the best results, choose top-quality AMSOIL synthetic diesel oil and additives. They boost engine performance and longevity.
How Often Should Diesel Oil Be Changed?
Best Oil Change Frequency
Check your vehicle’s owner’s manual for the best diesel oil change frequency. AMSOIL synthetic diesel oils are made for extended use beyond OEM-recommended intervals. Follow the product data sheet guidelines or verify with oil analysis. AMSOIL also offers top-notch synthetic gear oils and transmission fluids to keep your diesel engine running at its best.
