* Mineral gear oil with no additives. Improves gearchange. Vitrea M220 can be used in transfer box, diffs and probably engine as well.
Very similar to original specification Russian oil.  Heritage 80w Gear oil from Pennine Oils also suitable.






Normal supply to coil is from the ignition switch via the resistor (red wiring on diagram). During cranking the coil is feed with 12v from the starter circuit (orange wiring on diagram) to boost the spark strength. The coil is designed to be used with a resistor in series and will eventually burn out if fed directly with the full 12v.

Running on Contaminated fuel


Contaminated fuel is the mixture of diesel and petrol that is pumped out of the tank of a diesel vehicle that has been filled with petrol by accident. Garages often have to pay to get rid of this fuel and it is relatively easy to get hold of.

Most of the petrol engined Russian trucks will run on contam. with some good fuel added.  The percentage of diesel in the mix is unpredictable and will affect the amount of good petrol you have to add to get the truck running happily on it.

Using contaminated fuel is a risk to the engine if not managed properly as the diesel leaks past the pistons into the sump, diluting the engine oil. Frequent oil changes and starting and stopping on good fuel are recommended. If you are willing to do the extra work you can end up making some considerable savings though.
