What is the Difference Between CF4 and CH4 Engine Oil?

The main difference between CF4 and CH4 engine oils lies in their performance attributes, specifically in terms of oxidation control and dispersancy. CF4 engine oil has low oxidation control and poor dispersancy, while CH4 engine oil offers better oxidation control and improved dispersancy.

CF4 engine oil is a high-performance, heavy-duty engine oil primarily recommended for use in off-road applications such as mining and construction. It is designed for indirect injection diesel engines and can handle a broad range of fuel types, including those with higher sulfur levels. Key features of CF4 engine oil include thermal and oxidation stability, excellent detergency, and stay-in-grade shear stability.

CH4 engine oil, on the other hand, was introduced for high-speed four-stroke diesel engines using fuel with sulfur levels of up to 0.5%. It offers several additional performance attributes compared to CF4, including better oxidation control and improved dispersancy, which results in a cleaner engine. These oils are designed to meet the specific requirements of high-speed, four-stroke diesel engines and are particularly effective in engines meeting 1998 US EPA emission standards.

In summary, the key differences between CF4 and CH4 engine oils are:

• CF4 engine oil has low oxidation control and poor dispersancy.
• CH4 engine oil offers better oxidation control and improved dispersancy.
• CF4 engine oil is primarily designed for off-road applications, while CH4 engine oil is suitable for high-speed, four-stroke diesel engines.

Comparative Table: CF4 vs CH4 Engine Oil

The main difference between CF4 and CH4 engine oils lies in their oxidation control and dispersancy properties. Here is a table comparing the two:

CF4 engine oil is a high-performance, heavy-duty engine oil that provides proven protection to diesel engines operating in severe conditions. It is primarily recommended for use in Tata Motors Diesel Commercial Vehicles. The most important features of CF4 engine oil include thermal and oxidation stability, excellent detergency, and stay-in-grade shear stability.

CH4 engine oil, on the other hand, is designed for high-speed, four-stroke diesel engines meeting 1998 US EPA emission standards. It can be used with fuels containing up to 0.5% sulfur. CH4 engine oil provides better oxidation control and improved dispersancy compared to CF4 engine oil.
