How do you change the oil to a 1989 Suzuki sidekick?

To change the oil on a 1989 Suzuki Sidekick, start by warming up the engine for a few minutes to thin the oil, making it easier to drain. Then, secure the vehicle on a level surface, raise it with jack stands, and place an oil pan underneath the oil pan's drain plug. Remove the drain plug and let the old oil fully drain out, then replace the plug. Finally, remove the old oil filter, install a new one, and refill the engine with the appropriate type and amount of new oil through the oil filler cap.
