EXPLANATION OF MAINTENANCE ITEMS Engine Oil and Oil Filter Replace the oil filter and drain and refill the engine oil at specified intervals. SAE 0W-20 oil is the best choice for good fuel economy and good starting in cold weather. If SAE 0W-20 is not available, SAE 5W-20 may be used; however, it must be replaced with SAE 0W-20 at the next oil change. See your Lexus dealer for oil specifically formulated for your vehicle's engine. For instructions on how to reset the reminder light, refer to your Owner's Manual. Note: If you do the majority of your driving under any of the special operating conditions indicated on page 44, you should replace the engine oil and oil filter every six months or 5,000 miles, regardless of the oil used or the certification of the vehicle.
