The lower section will state energy conserving if the oil has proven fuel saving capabilities. Changing engine oil and filter Change your oil and filter according to the scheduled maintenance information in this supplement. Change more frequently if your vehicle operation includes extended periods of idling or low-speed operation, driving for a long time in cold temperatures or driving short distances.
