However, common recommendations for a 2000 Ford Ranger manual transmission often include SAE 75W-90 or 75W-140. 75W-90 is generally suitable for most climates, while 75W-140 is better for hotter climates or if you experience heavy loads. Using the wrong weight can lead to poor shifting and transmission damage.
Before adding any oil, consult your owner's manual. It will specify the correct grade and the correct amount of oil for your specific transmission. The manual will also list any approved Ford Motorcraft or other suitable oils. Using a non-approved oil can void warranties or cause damage.
