  • Gloves and safety glasses
  • Jack and jack stands (or car ramps)
  • Shop rags or paper towels

Step-by-Step DIY Oil Change:

  1. Safety First: Drive your car for a few minutes to warm the oil slightly (it drains better warm), but not hot. Park on a level surface. Engage the parking brake. Use a jack and jack stands (never rely solely on a jack) or drive onto car ramps to safely raise the front of your vehicle.
  2. Locate and Prepare: Place the drain pan directly under the oil pan drain plug.
  3. Drain the Old Oil: Using your socket wrench, carefully loosen and remove the drain plug. Be prepared for the oil to flow out immediately. Let it drain completely. Once the flow slows to a drip, replace the drain plug, ensuring it’s snug but not overtightened (check your manual for torque specs if you have a torque wrench).
  4. Replace the Oil Filter: Position the drain pan under the oil filter. Use your oil filter wrench to loosen the old filter. Once loose, unscrew it by hand. Some oil will spill, so be ready.
  5. Prepare the New Filter: Before installing the new filter, apply a thin film of new dexos 1 oil to the rubber gasket of the new filter. This ensures a good seal.
  6. Install the New Filter: Screw the new filter on by hand until it’s snug, then tighten it an additional 1/2 to 3/4 turn (refer to filter instructions for precise tightening).
  7. Add New Oil: Lower your vehicle. Locate the oil filler cap on top of the engine. Place your funnel in the opening and slowly pour in the recommended amount of new dexos 1 oil.
  8. Check and Finish: Replace the oil filler cap. Start the engine and let it run for a minute to circulate the new oil. Check for any leaks around the drain plug or oil filter. Turn off the engine, wait a few minutes, then recheck the oil level with the dipstick. Add more oil if necessary to reach the “full” mark.
  9. Dispose Responsibly: Pour the old oil from your drain pan into the empty new oil containers and take it to an auto parts store or local recycling center.
