The Recommended Fluids, Filters, and Components of the 2021 Ford Bronco

You don’t have your Bronco in the driveway yet, but here’s one more way you can prepare for its arrival, especially if you like to do your own maintenance –– the recommended fluids, filters, and components for the 2021 Ford Bronco. The all-new Bronco is engineered to use Motorcraft parts and fluids, and there are some interesting points in this list. Take the transmission fluid, for instance. Motorcraft MERCON ULV Automatic Transmission Fluid is the same that is used for the F-150 and F-150 Raptor with the 10R80 trans. The 13.1 quart capacity is slightly larger than the Ranger’s 12.8 quarts, likely to meet the off-road requirements Ford built in: The Bronco has best-in-class break-over and side-by-side angles, as we previously relayed. Relatedly, Bronco’s 2.7L EcoBoost requires seven quarts of oil, up from the Ranger’s six, to protect parts while you do bold activities.
