It can also be done 3-6 months after purchase. This is based on the newest manual. Some older manuals say 1,500-3,000 km. Among Genron’s clients, 90% of early engine issues come from skipping this first service. These problems include noise and oil burning. This step removes factory residues and sets a baseline for checks. So, you must complete these tasks in the first maintenance:<\/p>\n
