Mobil Multi-Vehicle ATF is a premium lubricant for car and truck automatic transmissions and other applications and recommended by ExxonMobil for use in applications that require an automatic transmission fluid satisfying Ford Mercon and Mercon V performance levels. Recommended by ExxonMobil for use in applications requiring Dexron III. Good maintenance practice dictates that automatic transmissions be checked for proper fluid levels at regular intervals, and that the fluid be drained and replaced at intervals recommended by the manufacturer.
