Mercury 3S7Z-6731-A Filter Assembly - Engine Oil - Elem

The oil maintenance is very important in taking care of your vehicle. The oil should be changed every 1,500 miles even if the oil life indicator says differently. To get ready, collect tools and rags and lift the car up for easy access. Do this only when the engine is slightly hot, but be careful about the exhaust being hot too. Park on a flat surface, take off the oil filler cap, and drain it into a pan. Clean and put back the drain plug; then take out and substitute the oil filter. The next step is to lower the vehicle, pour in new oil, and run the engine to see if it leaks anywhere.

Frequent oil changes are necessary to avoid pre-emptive maintenance. Have equipment and materials. Raise the car so you can easily work on it. Start the engine and let it run for a while. Find a flat spot, remove the oil filler cap, and put up the vehicle on jack stands. Put your drain pan under that plug and remove it. Check drained oil for metal shavings. Clean and reinstall plug. Position your drain pan below the filter, loosen it, unscrew it by hand. Clean the surface where filter going to sit then put in new one. Release the jack stands, replenish with new oil making sure that you fill until full, check level of the oil again. Check if there are leaks through starting up the engine and measuring the amount of oil left in the car's reservoir including other parts after which remove it carefully into an approved waste container so as not to pollute environment.
