How to Change the Oil and Filter on a 2014-2020 RAM 1500

Your RAM 1500’s oil filter helps trap and remove oil contaminants before it is recirculated throughout your truck’s engine, while oil lubricates the engine and absorbs heat. Changing your 2014-2020 RAM 1500’s oil and oil filter is a straightforward maintenance activity that can improve your RAM’s engine performance and longevity. Your truck’s oil filter should be replaced during each oil change, but excess debris or engine issues may cause your oil filter to collect excessive contaminants and clog before the specified oil-change interval. It’s recommended that you change your RAM 1500’s oil and oil filter when the Oil Change Light illuminates on your dashboard, as your RAM is built with an oil life monitoring system that allows for variation in the oil change interval. Your RAM’s service manual will detail the manufacturer’s maintenance intervals and the oil life indication system. A clogged oil filter or dirty oil can cause decreased engine performance, sputtering, metallic sounds from your RAM’s engine, or could even cause the engine to seize. Our detailed instructions will help you perform an oil change and oil filter replacement in your RAM 1500 to keep your truck running at its best.
