NEVER Do This After an Oil Change! (KILLS Your Engine Fast)

Summary

The video presents a countdown of nine oil-change mistakes that can damage an engine, followed by a practical post-change inspection routine. Its central advice is to check the work before driving away: leaks, installation errors, and oil-level problems can appear as soon as the engine runs.

Oil-change mistakes to avoid

1. Draining oil when it is stone cold or scalding hot. Warm oil flows more readily and can carry more suspended debris out, but oil straight after driving can cause burns. Let it cool until the oil pan is warm, wear gloves, and allow the oil to drain to a slow drip.

2. Overfilling. Excess oil can be whipped into foam by the crankshaft, reducing lubrication, or enter the ventilation system. Check the vehicle’s capacity and the dipstick on level ground, and add oil gradually. Correct a significant overfill before driving.

3. Using the wrong oil. Match both the viscosity grade, such as 0W-20, and the required industry or manufacturer specification in the owner’s manual. The video notes that mixing brands is acceptable if the grade and specification match, and recommends keeping receipts as maintenance records.

4. Installing a filter dry or overtightening it. Lightly coat a spin-on filter’s rubber gasket with clean oil, then hand-tighten it according to the filter instructions. For cartridge filters, use and oil the new O-ring, seat it correctly, and follow the housing’s torque specification.

5. Assuming a filter is correct because it fits. Filters with similar threads may differ internally, including in their anti-drainback and bypass valves. Verify the part number for the engine and compare the old and new filters. Brief rattling at startup after a change may indicate that oil has drained out of the filter overnight.

6. Overtightening the drain plug or reusing a single-use washer. Excess torque can strip or crack an oil pan, particularly an aluminum one. Start the plug by hand, use the correct replacement washer or plug, and tighten it to the vehicle’s specification with a torque wrench.

7. Ignoring or failing to reset the oil-life monitor. The monitor estimates oil use based on operating conditions, but it is not a substitute for the owner’s manual. Reset it after service and account for severe use—such as frequent short trips, towing, or stop-and-go driving—as well as time and mileage.

8. Leaving the old filter gasket in place. Installing a new filter over the old gasket can create a double seal that may fail under oil pressure and rapidly dump oil. Confirm the old gasket came off, feel around the mounting surface, and clean it without scratching the surface.

9. Driving away without checking the work. This is presented as the most consequential mistake because it can allow other errors to go unnoticed. Start the engine and confirm the oil-pressure light goes out within a few seconds. Inspect the filter and drain plug for leaks, then shut the engine off, wait, and recheck the dipstick. Also confirm the filler cap and dipstick are in place, tools and rags are removed, and any splash shield is secured. Recheck the oil level and parking spot the next morning, and watch for drips over the following days.

Additional guidance

• Safety: Never work beneath a vehicle supported only by a jack. Use jack stands or ramps on firm, level ground, chock the wheels, and check stability before going underneath.
• Oil condition: Watch for metallic glitter, widespread milky oil, or a strong gasoline smell. The video distinguishes widespread milky oil from a little creamy residue under the filler cap, which can result from condensation in vehicles driven mostly on short trips. Laboratory oil analysis is another option for monitoring engine wear.
• Disposal: Store used oil in a sealed container and take it to a parts store or recycling center. Do not pour it out.
