Maintenance and Specifications Engine oil and filter recommendations Look for this certification trademark. SAE 5W-20 engine oil is recommended. 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. SAE 5W-20 oil provides optimum fuel economy and durability performance meeting all requirements for your vehicle's engine. Do not use supplemental engine oil additives, cleaners or other oil treatments or engine treatments. They are unnecessary and could, under certain conditions, lead to engine damage which is not covered by your warranty. Change your engine oil and filter according to the appropriate schedule listed in the scheduled maintenance guide. Ford production and aftermarket (Motorcraft) oil filters are designed for added engine protection and long life. If a replacement oil filter is used that does not meet Ford material and design specifications, start-up engine noises or knock may be experienced. It is recommended you use the appropriate Motorcraft oil filter (or another brand meeting Ford specifications) for your engine application. 228 2003 Town Car (tow) Owners Guide (post-2002-fmt) USA English (fus)
