- Unscrew plug 1;
- add oil (for reference: spacing between marks «mini» And «maxi» dipstick 2 corresponds to a volume of 1.5 to 2 liters, depending on the engine model);
- wait about 10 minutes for the oil to completely glass;
- check the oil level with dipstick 2 (as mentioned above).
After checking the level, insert the dipstick until it stops or tighten the dipstick plug until it stops.
