To meet consumer demand, automakers are building cars with smaller engines (for greater fuel efficiency) but adding turbochargers (to boost power). We already mentioned how engines run at high temperatures, which can break down conventional oils faster, but today’s turbocharged engines are even more aggressive. The shaft inside a turbocharger can spin upwards of 200,000 revolutions per minute, so it’s critical that your motor oil can get to that shaft and lubricate it properly very quickly.
Conventional oils can break down faster under these conditions and leave deposits on turbocharger components, which can lead to failure. Synthetic oils can protect these components much better than conventional oils, keeping them operating at peak performance and boosting your engine’s power.
