Ford recommends using Motorcraft (Ford) DOT 3 High Performance Motor Vehicle Brake Fluid
or equivalent meeting WSS-M6C65-A1. Use of any fluid other than the recommended fluid may
cause degraded brake performance and not meet the Ford performance standards. Keep brake
fluid clean and dry. Contamination with dirt, water, petroleum products or other materials may
result in brake system damage and possible failure.

Add the coolant type originally equipped in your vehicle.

Use of synthetic or synthetic blend motor oil is not mandatory. Only use fluid that meets Ford
specification. Motor oils of the recommended viscosity grade that meet API SN requirements and
display the API Certification Mark for gasoline engines are also acceptable. Do not use oil labeled
with API SN service category unless the label also displays the API Certification Mark.
An oil that displays the API Certification Mark conforms to current engine, emission system and
fuel economy performance standards of the International Lubricant Standardization and Approval
Committee (ILSAC).
Do not use supplemental engine oil additives in your engine. They are unnecessary and could
lead to engine damage that is not covered by your Ford warranty.

Automatic transmissions that require MERCON LV should only use MERCON LV fluid. Refer to
scheduled maintenance information to determine the correct service interval. Use of any fluid
other than the recommended fluid may cause transmission damage.
