40 to 55
- If your vehicle runs on diesel, you have probably noticed that no octane figures are advertised. Instead, diesel fuel is rated with a “cetane number,” which ranges from 40 to 55 around the world. Just like with gasoline, the higher number, the better the fuel.

Which octane fuel is best for a diesel engine?
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without causing engine knocking. The higher the octane number, the more compression the fuel can withstand before detonating.

Cetane number is a measure of the fuel oil’s volatility; the higher the rating, the easier the engine will start and the smoother the combustion process will be within the ratings specified by the engine manufacturer. Current 1D and 2D diesel fuels have a cetane rating between 40 and 50. Cetane rating differs from the octane rating used in gasoline...
Diesel Fuel fuel volatility requirements depend on the same factors as cetane number. The more volatile fuels are best for engines where rapidly changing loads and speeds are encountered. Low volatile fuels tend to give better fuel economy where their characteristics are needed for complete combustion, and will produce less smoke, odor, deposits, c...
The viscosity of diesel fuel is a measure of the resistance to flow of the fuel, and it will decrease as the fuel oil temperature increases. What this means is that a fluid with a high viscosity is heavier than a fluid with low viscosity. A high viscosity fuel may cause extreme pressures in the injection systems and will cause reduced atomization a...
Lubricity is commonly defined as the ability of a fluid to minimize the degree of friction between surfaces in relative motion under load conditions. When the lubricity is not at a satisfactory level, then many internal engine components including fuel pumps and injectors are prone to excessive wear and metal damage. The results of such wear are in...
Sulfur has a definite effect on the wear of the internal components of a diesel engine, such as the piston ring, pistons, valves, and cylinder liners. In addition, a high sulfur content fuel requires that the engine oil and filter be changed more often because the corrosive effects of hydrogen sulfide in the fuel and the sulfur dioxide or sulfur tr...
The life blood of your diesel engine is diesel fuel and the major enemy of fuel injection systems is poor quality fuel. From extensive research and testing, we have found that variations in fuel quality around the world can adversely affect today’s precision fuel injection systems. Poor quality fuel can cause performance issues, premature wear, gum...
Feb 21, 2024 · An octane rating measures the amount of the molecule that is in everyday gasoline. The higher the octane number, the greater the fuel's resistance to knocking. Since knocking can damage an engine, octane is very in-demand!
Sep 10, 2024 · While octane ratings are critical for gasoline engines to prevent knocking, diesel engines rely on a high cetane number for efficient ignition and combustion. Therefore, asking about the octane rating for diesel (diesel fuel octane rating) is a common misunderstanding—what matters for diesel fuel is its cetane rating, not an octane number.
Octane rating, also known as octane number is a measurement of the quality or performance of gasoline. The higher the number, the better the fuel burns within the engine of a vehicle. Higher performance vehicles require fuels with a higher octane rating.
Nov 17, 2022 · Octane ratings are measures of fuel stability. These ratings are based on the pressure at which a fuel will spontaneously combust (auto-ignite) in a testing engine. The octane number is actually the simple average of two different octane rating methods— motor octane rating (MOR) and research octane rating (RON)—that differ primarily in the ...
