<p>A fuel mixture for a compression ignition device is provided, comprising a mixture of used oil and fuel material in a ratio that increases the fuel efficiency of the device in comparison to the efficiency of the device when operated without the used oil. In a fuel mixture according to the present invention, the amount of used oil in the mixture is not more than 60% by volume of the mixture, is in a general target range of 25% to 60% (by volume) and is preferably about 37% to about 42% by volume. Moreover, it is preferred that the used oil is filtered at a predetermined level. The preferred filter level is a 5-micron level, followed by a plurality of passes, at low speeds, through 10-micron paper filter.</p> |
