Oil filter

The full-flow oil filter is screwed manually until it stops against the sealing gasket, then turned half a turn. The filter is replaced every 10,000 km.

To make it easier to unscrew the filter, wrap a strip of sandpaper 60-70 mm wide around the filter with the sandpaper side facing the filter, or use a special device.
