Petrol models
Unleaded gasoline is not worse than AI-95/A-85, temporary use of unleaded gasoline is not worse than AI-91/A-82.5. In this case, the engine power will decrease slightly, with an increase in fuel consumption.
Do not use fuel additives. They can cause increased wear or damage to the engine.
Diesel models
Summer and winter diesel fuel No. 2 or No. 1 according to ASTM D975.
Do not use judgment (Marine Diesel Fuel), boiler room, etc. diesel fuel.
When using diesel fuel with a sulfur content of more than 0.5%, change the engine oil every 7500 km.
Winter fuel, ensures normal performance down to -20°C.
Thanks to the preheating of the fuel when the vehicle's heating system is switched on, a winter diesel vehicle can generally be operated without failures at ambient temperatures down to -25°C.
Do not mix gasoline with diesel fuel.
In the case of using summer diesel fuel, as well as at outdoor temperatures below -15°C, a certain amount of flow improver or kerosene, depending on the outdoor temperature, must be added to the fuel.
Flow improvers can also be used in combination with kerosene.
You can get a certificate of funds at the service station.
The proportion of the additive, taking into account the outside temperature, should be minimal.
The proportion of kerosene in the mixture should be no more than 50%.
Add the additive to the diesel fuel until the diesel fuel loses its fluidity due to the release of paraffin. Malfunctions due to waxing can only be eliminated by heating the entire power system.
Mix diesel fuel with kerosene only in the fuel tank. To do this, first fill the tank with kerosene, and then add diesel fuel.
After that, the engine must run for some time in order for the mixture to be distributed throughout the entire power system.
Fire hazard! Kerosene additives lower the flash point of diesel fuel. As a result, the danger when handling the fuel mixture increases. Observe the relevant safety regulations!
