Guidelines for vehicle longevity emphasize the importance of regular maintenance for engine oil, gearbox oil, and coolant. For engine oil, maintenance intervals vary based on driving conditions and engine type; for example, standard intervals may be reduced from 15,000 km to 7,500 km under demanding conditions, or as frequently as every 2,500 km for turbocharged engines.

Proper gearbox maintenance is also noted, with automatic gearboxes often requiring service every 60,000 to 80,000 km. Additionally, monitoring coolant is essential for temperature regulation. Regarding oil composition, mixing different viscosities may alter technical properties and flow characteristics, potentially reducing component protection if the mixture fails to meet manufacturer specifications.
