Stop-start systems are another engineering response to changing fuel economy and greenhouse gas regulations. This technology is gaining popularity too with car makers, employing it across their entire lines. Understanding what’s behind stop-start technology has never been so important.
 

Proving Mobil 1™ lubricant technology in the lab


ExxonMobil engineers study the lubricant technology of Mobil 1 oils through specialised stop-start testing – 300,000 stop-start cycles at a time. The engineers aim to create punishing real-world conditions as would occur during the life of the vehicle, which helps them accurately measure the performance and protection of Mobil 1 oils within stop-start systems.

After simulating driving 120,000 miles with extended oil drain intervals, which translates to about 80 daily stop-start cycles, ExxonMobil engineers determined that Mobil 1 ESP 5W-30 demonstrated excellent performance while providing wear protection under extreme stop-start operations.
