Pull out the dipstick to check (oil level gauge) and wipe it off with a clean cloth.
Reinsert the dipstick and pull it out again. The oil level must be between the upper and lower marks.
If the oil level is at the bottom mark, you need to add oil. The volume of oil between both marks is approximately 1 liter, so you can infer from this how much oil is missing.
Never overfill the engine with oil, i.e. its level should not rise beyond the upper mark.
Every 10 thousand kilometers or at least once a year, you need to change the engine oil and oil filter. The oil change interval should be shortened if the car is often driven with a trailer or in very dusty conditions, with continuous trips over short distances (e.g. commuting less than 7-8 km), at air temperatures below zero or at frequent stops in traffic jams, when the engine must be idling for a long time.
Raise the car in front (if it is needed) and remove the oil drain plug on the bottom of the oil pan.
To speed up the draining of the oil, remove either the oil filler cap or the oil level indicator. The oil should be warm, but not hot
After draining the oil, clean the drain plug and screw it back into place.
Oil filter - replacement
To replace the filter element, it is recommended to use a special key. Such a key can be purchased at many stores, on the market, or made independently.
If a key is not available and the filter needs to be replaced, you can drive a screwdriver or a punch into the filter and unscrew the filter.
A device for turning off the oil filter, made independently
1 - a strip of thin metal or emery cloth, folded in half with a cutout;
2 - axis;
3 - lever (screwdriver, etc.)
After unscrewing the filter, carefully clean the seat on the cylinder block and lubricate the filter gasket with engine oil. Screw on the new filter until the o-ring snaps in and tighten it from this position 1/2-3/4 turn by hand without applying any additional force.
Fill the engine with oil through the oil filler neck.
Start the engine and let it run for a while. Check that the filter connection is not leaking.
