Engine Oil Recommendations 4.6L Engine Look for this certification trademark. Use SAE 5W-20 engine oil. Only use oils "Certified For Gasoline Engines" by the American Petroleum Institute (API). To protect your engine's warranty use Motorcraft SAE 5W-20 or an equivalent 5W-20 oil meeting Ford specification WSS-M2C153-H.

Do not use supplemental engine oil additives, cleaners or other engine treatments. They are unnecessary and could lead to engine damage that is not covered by Ford warranty. Change your engine oil according to the appropriate schedule listed in the scheduled maintenance guide. 230 2003 Explorer (exp) Owners Guide (post-2002-fmt) USA English (fus)
