Diesel/kerosene mix fuel

I was wondering if anyone knows if it's ok to run a diesel/ kerosene mixed fuel it's pretty much alot of diesel mixed with a lil bit of kerosene they use it up here at wrk for heaters n such. It's usually just kerosene but they accidenty ordered diesel instead. Thanks!

KEROSENE BLENDED DIESEL FUEL

Introduction

Kerosene is frequently blended with diesel fuel to improve winter fuel operability. A kerosene blended diesel fuel is one that combines #1 diesel fuel (i.e. kerosene) with #2 diesel fuel. The ratio of diesel fuel to kerosene is typically found in the range of 80:20, 70:30, 60:40, or 50:50.

Costs of Kerosene Blending

Kerosene blending is not a cost-effective method of achieving desired winter fuel operability. In most cases, treating fuel with a cold flow improver additive such as Diesel Aid, Artic Power, and/or Artic Flo is the most cost effective solution. To calculate the cost differential between blending with kerosene versus using a cold flow improver additive, perform the following analysis:

1) Determine the cost of kerosene and #2 diesel fuel ($/gallon)
2) Determine blending ratio (i.e. 70:30, 50:50)
3) Calculate amount of kerosene needed (gallons)
4) Calculate cost differential ($)
5) Determine treat rate and cost of additive ($/gallon)
6) Calculate net savings (kerosene cost - additive cost)

Example

1) Assume kerosene costs $0.08 per gallon more than diesel fuel
2) Assume 50:50 blend at 42,000 gallons
3) Kerosene needed equals 21,000 gallons
4) Cost differential equals 21,000 x $0.08 = $1,680
5) Assume 1 ounce of additive treats 30 gallons. At $0.01 per gallon, cost of additive to treat 42,000 gallons equals $420 ($0.01 x 42,000).
6) Net Savings = $1,680 - $420 = $1,260

Conclusion:

The net savings equals $1,260 or $0.03 per gallon using a cold flow improver additive instead of a 50:50 kerosene blend.

Other Disadvantages of Kerosene Blending

Kerosene has a lower BTU content than #2 diesel fuel which results in a decrease in engine power and fuel economy. Kerosene has an average BTU content of approximately 133,500 BTU per gallon and #2 diesel fuel has an average BTU content of approximately 139,500 BTU per gallon.

When using a 50:50 kerosene blend, the BTU content is approximately 136,500 or two percent less than #2 diesel. The resulting power loss is approximately two percent. Fuel economy will also decrease by at least two percent.

Kerosene provides only minimal increased winter fuel operability. Kerosene will decrease the Cold Filter Plug Point (CFPP) by 2F for every 10% kerosene used. Diesel fuel additives, on the other hand, will reduce the CFPP by as much as 35F- 45F.

Kerosene contains less lubricity than #2 diesel fuel. Diesel fuel lubricity is a major concern because of Ultra Low Sulfur Diesel (ULSD). ULSD contains significantly less lubricity than Low Sulfur Diesel (LSD). As a result, metal components in the engine fuel system, including fuel pumps and injectors, are susceptible to premature failure. Many diesel fuel additives will actually increase overall fuel system lubricity.

Kerosene contains less cetane than #2 diesel fuel. Cetane is the most universally accepted measure of diesel fuel ignition quality. Proper ignition during the combustion cycle is essential for optimum operation, economics, and durability. Insufficient levels of cetane lead to hard starting, longer warm-ups and heavy white smoke.

Summary of Disadvantages of Kerosene Blending

1) Increased Cost
2) Decreased Engine Power
3) Decreased Fuel Economy
4) Inadequate Winter Fuel Operability
5) Decreased Lubricity
6) Decreased Cetane

Conclusion

Diesel fuel additives are the most economical and effective means of improving winter fuel operability. It costs less to treat a gallon of diesel fuel with diesel fuel additives than it does with kerosene. Blending a diesel fuel additive with #2 diesel fuel will improve winter fuel operability without decreasing engine power and fuel economy. The advantages of using diesel fuel additives include: (1) increased engine power and fuel economy; (2) increased winter fuel operability; (3) increased fuel system lubricity; and (4) increased cetane. E-ZOIL manufacturers several diesel fuel additives formulated to achieve these advantages including DIESEL AID, ARTIC POWER, ARTIC FLO, and CLEAN & LUBE.

If it was bought to run in heaters, and stored in tanks for heaters, it may not be filtered all that well.

Price up a set of fuel filters. You might need them.
