The paper outlines properties of tallow to be used as fuel, its production process and annual variation of the measured parameters – density, acidity, impurities, calorific value etc. Most of the parameters are constant throughout the year, except acidity.   Acidity is high during the summer and low in winter – this is consistent with environmental temperature changes. High levels of free fatty acids are consistent with the perceived low quality of fat and are also responsible for the unpleasant bitter taste of rancid fat. Admissible acidity levels of fuel for the four- and two-stroke heavy fuel oil (HFO) engines indicate that in winter the two stroke engine may be used, but in the summer acidity levels are generally too high. Possible industrial methods of acidity reduction are briefly discussed.
