Why does BMW use synthetic oil?

1. Durability: Synthetic oils can perform well and can withstand extreme temperatures, which is necessary in BMW engines that typically operate at higher temperatures.

2. Resistance to oxidation and thermal breakdown: Synthetic oils have a longer service life compared to conventional oils due to their resistance to oxidation and thermal breakdown, which can lead to sludge and deposit formation in engines.

3. Improved fuel efficiency and performance: Synthetic oils' advanced formulations can contribute to improved fuel efficiency and engine performance by reducing friction between engine components.

4. Longer oil change intervals: BMW often recommends extended oil change intervals when using synthetic oils, as they maintain their properties for longer periods.

5. Compatibility: BMW engineers design their engines with synthetic oils in mind, ensuring compatibility with engine parts and seals.
