For preventive maintenance, regular oil changes are essential. Aging engine oil will become diluted and contaminated, leading to premature engine wear. This is because replacing the oil filter with each change has low costs and easy installation. Find the oil drain plug and filter without hitting hot exhaust parts. Return to running condition after starting it, let the engine warm up, and park it on flat ground which turns it off again. Make sure the car is safely raised; then put a glove on while removing the plug and place the pan below it. Ensure all of the oil has been drained out completely while checking for metal particles as well. Once dry, reinstall the plug as well as move the pan beneath the filter. At this point, apply some lubricant to the gasket of the new filter after tightening it with your hand, and then lower the car down. Add five quarts of fresh oil into it, check the level through the dipstick before finally starting the engine for a short time.

Maintenance for prevention requires frequent oil changes. Collect rags and tools in the event of spillage. While cars are on ramps, filters and drain plugs can be reached. Begin the engine up, let it warm up fully, then park it on a level surface. Lift the car with stands and put the pan below the plug. Remove the oil, check for metallic particles, and clean up its plug as well as opening filter surfaces. Fit a new filter lubricating its gasket then filling it with new oil. Check the dipstick level and watch out for any drips. You may have to drop off used oil at a reclamation center or recycling facility.

After draining the old oil, inspect it for metal particles, wipe the drain plug, reinstall it securely, and move the drain pan under the oil filter.

Move the drain pan under the oil filter and loosen the filter using a filter wrench. If the filter is too tight, puncture it with a metal bar or long screwdriver to loosen it. Unscrew the filter from the block, being careful to prevent oil from spilling out.
