Can some kerosene be added to diesel fuel 6.5 diesel?

It is not recommended to add kerosene to diesel fuel in a 6.5 diesel engine. While kerosene and diesel are both distillate fuels, they have different properties and can affect engine performance and longevity. Here's why adding kerosene to diesel fuel can be problematic:

1.Cetane Number: Kerosene has a lower cetane number than diesel fuel. Cetane number represents a fuel's ignition quality or how quickly it ignites after injection. A lower cetane number indicates a longer ignition delay, which can result in rough engine operation, increased noise, and reduced power output.

2.Energy content: Kerosene has a lower energy content compared to diesel fuel. This means that when mixed with diesel, the overall energy density of the fuel blend decreases. As a result, the engine may experience a loss of power and reduced fuel efficiency.

3.Lubricity: Diesel fuel contains lubricity additives that help reduce wear and tear on the fuel injection system and other engine components. Kerosene lacks these additives, so adding it to diesel can diminish the fuel's lubricating properties, potentially causing premature wear and damage to the engine.

4.Compatibility: Kerosene and diesel fuels may not be fully miscible, leading to phase separation or instability in the fuel blend. This can cause issues with fuel flow, filter clogging, and injector problems, potentially disrupting engine performance and reliability.

5.Emissions: Adding kerosene to diesel fuel can alter the exhaust emissions profile of the engine. It may increase the emission of harmful pollutants such as unburned hydrocarbons, carbon monoxide, and particulate matter, impacting environmental regulations and air quality.

It is important to use the fuel specified by the engine manufacturer to ensure optimal performance, reliability, and longevity of your 6.5 diesel engine. If you have concerns about fuel quality or performance, consult with a qualified mechanic or refer to the vehicle's owner's manual for specific fuel recommendations.
