Maintenance and Specifications to the current engine and emission system protection standards and fuel economy requirements of the International Lubricant Standardization and Approval Committee (ILSAC), comprised of U.S. and Japanese automobile manufacturers. To protect your engine's warranty use Motorcraft SAE 5W-20 or an equivalent SAE 5W-20 oil meeting Ford specification WSS-M2C930-A. 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 engine treatments. They are unnecessary and could lead to engine damage that is not covered by Ford warranty. Change your engine oil and filter according to the appropriate schedule listed in scheduled maintenance information. 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 with equivalent performance for your engine application. BATTERY Your vehicle is equipped with a Motorcraft maintenance-free battery which normally does not require additional water during its life of service. If your battery has a cover/shield, make sure it is reinstalled after the battery has been cleaned or replaced. For longer, trouble-free operation, keep the top of the battery clean and dry. Also, make certain the battery cables are always tightly fastened to the battery terminals. If you see any corrosion on the battery or terminals, remove the cables from the terminals and clean with a wire brush. You can neutralize the acid with a solution of baking soda and water. 290 2008 Sable (mgo) Owners Guide (post-2002-fmt) USA (fus)
