guide comes to life with practical steps.

  1. Locate and Loosen Drain Plug: Place your drain pan directly under the oil pan drain plug. Using the correct wrench, carefully loosen the plug. Be prepared for oil to flow out quickly once the plug is removed.
  2. Drain Oil Completely: Allow all the old oil to drain into the pan. This usually takes 10-15 minutes. While it’s draining, inspect the drain plug and gasket for wear. Replace the gasket if necessary.
  3. Replace Oil Filter: Move the drain pan under the oil filter. Use an oil filter wrench to loosen and remove the old filter. Be aware that some oil will spill. Apply a thin film of new Lucas Oil 10W40 to the rubber gasket of the new filter before screwing it on. Hand-tighten the new filter until snug, then give it another quarter to half turn with the wrench (check filter instructions).
  4. Reinstall Drain Plug: Once the oil has fully drained, clean around the drain plug opening. Reinstall the drain plug, tightening it to the manufacturer’s specified torque. Do not overtighten, as this can strip the threads.
  5. Add New Oil: Using a clean funnel, carefully pour the recommended amount of fresh Lucas Oil 10W40 into the engine’s oil fill cap. Refer to your owner’s manual for the exact capacity.
  6. Check Oil Level: After adding the oil, wait a few minutes for it to settle. Check the dipstick. The level should be between the “add” and “full” marks. Start the engine, let it run for a minute to circulate the oil, then shut it off. Wait another few minutes and recheck the dipstick, topping off if needed.
