Maintenance and Specifications Adding engine oil 1. Check the engine oil. For instructions, refer to Checking the engine oil in this chapter. 2. If the engine oil level is not within the normal range, add only certified engine oil of the recommended viscosity. Remove the engine oil filler cap and use a funnel to pour the engine oil into the opening. 3. Recheck the engine oil level. Make sure the oil level is not above the MAX mark on the engine oil level indicator (dipstick). 4. Install the indicator and ensure it is fully seated. 5. Fully install the engine oil filler cap by turning the filler cap clockwise 1/4 of a turn until three clicks are heard or until the cap is fully seated. To avoid possible oil loss, DO NOT operate the vehicle with the engine oil level indicator and/or the engine oil filler cap removed. Engine oil and filter recommendations Use SAE 5W-50 full synthetic engine oil. To protect your engine's warranty use Motorcraft SAE 5W-50 full synthetic or an equivalent 5W-50 full synthetic oil meeting Ford specification WSS-M2C931-A. SAE 5W-50 full synthetic oil provides 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 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. 149 2005 GT (gto) Owners Guide (post-2002-fmt) USA_English (fus)
