cheap diesel how ?
-
there is always a fixed cost of producing a product then cost of blends , even if a company sells in bulk the cost wont be so drastically low , not to mention the cost involved at the retial end , land electricity storage workers etc , so how come taxi drivers are offered cheap diesel , dont know how but this is what i found on net
1. Can you use kerosene instead of diesel?
A A diesel engine will run fine on kerosene. If you are going to run it on kerosene for an extended amount of time you might want to put some lubricant additive in with it.

2. KEROSENE BLENDED DIESEL FUEL
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.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 2ºF for every 10% kerosene used. Diesel fuel additives, on the other hand, will reduce the CFPP by as much as 35°F- 45°F.
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(http://www.ezoil.com/Resources/Kerosene_Blended_Diesel_Fuel.html)

now for those who have been pumping diesel at company filling stations and know how Kerosene oil smells like can guess what is happening , not to mention the following common complains by Taxi drivers here
Decreased Engine Power
Decreased Fuel Economywhat i have noticed that if you use company oil and park your taxi in shade for 4 hours the engine is still very hot but if you do the same with petrol station diesel the engine cools down a lot. perhaps just my feeling

u mean company tao kai on diesel??
