I have heard that there’s never any need to put any additives in diesel fuel. Is this so?
No! That statement was made by Mike Allen a writer for Popular Mechanics magazine. While they can add a few more dollars to operating cost, they reduce the risk of the engine having problems with untreated fuel. The risks are water contamination, which can cause injection failure. Additives stabilize the water, preventing from accumulating in large quantities. Prevent injection nozzle deposits which cause poor fuel atomization and fuel consumption. There are also lubrication problems with less sulfur in the fuel today, which additives can remedy. Additives can also increase your cetane number. So additives in diesel fuel are a good idea!
The picture on upper the left shows the BG Diesel Fuel Lubricant with Conditioner. It provides the necessary film strength and lubricity to low-sulfur and ultra-low sulfur diesel fuel to prevent fuel pump and injection parts from scoring and seizing. One thing that is pretty good about this product is that just Two ounces (60 mL) of BG Diesel Fuel Lubricant with Conditioner treats up to 40 gallons (150 Liters) of diesel fuel. Catalytic converter and oxygen sensor safe. Part No. 227D
