What is the importance of frequent oil and filter changes for preventive maintenance on Mercury Cougar?

When it comes to preventive maintenance, the most important thing is regular oil changes since oil ages and gets contaminated over time causing premature engine wear. Gather all tools needed for an oil change. Lift the car to make it easier to reach the filter and plug. Next, start the engine, warm it up, and then park on a leveled ground. After raising the vehicle to a comfortable height, place a drain pan below the drain plug and then cautiously pull it out. In addition, you should check if there are any metallic particles in it before cleaning it properly and reinstalling it tightly. Afterwards, put your pan under the filter, and remove it after cleaning its surface, compare old vs new filters. Lubricate with fresh oil on the new filter seal put by hand and lower the vehicle down. Fill with fresh oil making sure that the level is correct before starting up again to check for any leaks finally rechecking the oil level upon completion of all activities stated above. Dispose of used motor oil properly anyway.

Mercury Cougar Oil Filter

The function of the Oil Filter of Mercury Cougar automobiles is to retain contaminants and allow clean oil to pass through its system explicitly. Filter types include replaceable element cartridge filters and spin-on filters and thus, the major objective is to achieve efficient separation of contaminants from the oil with maximum allowable oil flow rate. The performance filters are made to handle high oil pressures and their filtration standards are higher than ordinary filters, thus avoiding harm to the engine and its durability is assured. Thanks to the use of specific synthetic media these filters can have a capture rate of up to 99% of all the bad particles and at the same time let though a lot of oil flow. Development of oil filters has brought improvements in engines by improving the engines performance, oxidizing stability of oils thus extending the intervals between oil changes in order to protect the engines from the elements and thus increasing the engine's durability.

We provide a wide range of Mercury Cougar Oil Filter at the best prices possible. If you need Mercury Cougar Oil Filter, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your door step with a fast delivery service.
