HOW TO CHANGE ENGINE OIL Changing the engine oil at a regular interval is very essential to achieve quality engine performance. In so doing, the following tools and materials should be prepared: drive-on ramps, jack and jack stands, socket wrench or box end wrench to fit drain plug, droplight or flashlight, pour spout, drain pan, rags, fender covers, fresh motor oil, work gloves, and safety goggles. With these tools and materials ready on hand, the process could be started. First, raise the front of the car and support it with jack stands (unless working clearance under the car is adequate). Place a basin beneath the drain plug. Loosen oil drain into the basin. Clean the drain plug and washer with rags (some plugs are magnetized to trap metal particles). Next, replace the plug and washer as soon as old oil had drained. Start plug by hand and tighten it as far as possible. When the plug is seated, tighten it another half-turn with a wrench. Finally, find oil filter. Add amount of oil given in the owner's manual, 1qt. Less filter is not changed. Start engine and check for leaks at the drain plug. Lower the car, check oil level
