Kerosene to clean injectors ?

[bi222444]

The fuel oil man was making a delivery to my house while I had my
Bird idling to charge up the air system. As ususl there was some blue /
grey smoke coming out of the exhaust until it warmed up. He suggested
that I add some kerosene to the fuel and it would clean the injectors.
Kerosene and diesel being very close to one another,chemically and BTU
wise, with kerosene having less viscosity and less lubricating
propertiies. He also stated that the fuel companies are now taking the
sulphur by product from the refining of low sulphur fuel and are
dumping into the normal the #2 oil !!! He suggested I could put ss much
as 50 gallons into my 150 gallon tank. Any thoughts or experience with
this ?
