The oil in the engine should be changed at least once a year. As suggested by the manufacturer, change intervals depend on: • the selected engine oil, • vehicle operating conditions (city or highway conditions), • climatic conditions. Oil level in crankcase is checked by dipstick. The oil level should be in the middle of the scale, between the minimum and maximum scale marks of the dipstick. The difference between the minimum and maximum scale marks is approximately 20% of the amount of oil in the crankcase. If the oil level is below the “min”, then it is not enough. Lack of oil leads to increased wear of engine components, since they are insufficiently lubricated and cooled. It is recommended to check the level regularly after every 1000 km and especially after long trips. In case you notice an increase of oil consumption, immediately contact an authorized service center.
