How do you do an oil change on a 1972 vw beetle?

To change the oil on a 1972 VW Beetle, first, warm up the engine slightly to thin the oil, then turn it off and allow it to cool briefly. Place a drain pan under the oil sump, remove the drain plug with a wrench, and let the old oil drain completely. Replace the drain plug and tighten it securely, then remove the old oil filter, lubricate the rubber gasket on the new filter, and install it. Finally, pour new oil (generally 10W-40) into the engine through the filler cap, checking the dipstick to ensure the correct level.
