Withstanding high engine temperature is one of the most vital tasks a motor oil must accomplish. Mobil 1 resists high-temperature oxidation and helps prevent oil thickening, which can cause engine performance to decrease over a prolonged period.

That is why it is important to have a synthetic motor oil that can handle elevated operational temperatures. Mobil 1 is tested at extreme temperatures to ensure outstanding performance. By preventing deposit formation, Mobil 1 helps an engine to maximize its expected life while keeping it properly protected at extreme temperatures.
