Fuel
Gasoline models - Unleaded gasoline is not worse than AI-95
Diesel models - Diesel fuel with a cetane rating of at least 49
Operation of diesel models in winter conditions
When using a summer version of diesel fuel at temperatures below 0°C, interruptions in the operation of the engine may occur, due to an increase in the viscosity of the fuel as a result of wax release.
At low temperatures, use a special «winter» diesel fuel. Depending on the brand, winter fuel ensures uninterrupted operation at temperatures from -15°С to -22°С.
It is not allowed to use gasoline, etc. as additives to diesel fuel. thinners!
If the fuel quality is poor, the fuel filter may need to be replaced more frequently than the maintenance schedule suggests.
