The role of the engine oil in your Mercury Grand Marquis is to lubricate your engine to assure that all the gears in it can run efficiently , and to preserve the integrity of each of its components.

These oils can be purchased in 5 litre cans. We will now check out the different criteria for purchasing engine oil for Mercury Grand Marquis :

  • The cold viscosity of engine oil for Mercury Grand Marquis (number in front of the letter “W”, which stands for “Winter”): This value will signify the engine’s ability to start cold based on the viscosity of the oil. 0W means -30°C; 5W means -25°C, 10W means -20°C and 15W means -15°C. It is therefore up to you to adapt it to the weather conditions in which you drive your Mercury Grand Marquis.
  • The hot viscosity of the engine oil for Mercury Grand Marquis (value following the “W”): Value between 20 and 60, it is essential to remember that the higher the value, the thicker the layer of oil you will have when hot to protect your engine, and the lower the value, the less friction you will have when hot and therefore lower your consumption. However, if you use your Mercury Grand Marquis in the city, or with a sporty driving style, it’s better to protect it while hot.
  • The standards : They are written on the back of the oil canister you can discover them such as “ACEA C1 – C4” or “VW 500. 01”, are just standards of compatibility with different brands of cars, you have to verify in the instructions of your Mercury Grand Marquis that the oil in question is compatible with your engine.
  • Oil brands: Please take note that the brand should have very little effect in your judgement, there are enough objective criteria in the composition of motor oil for Mercury Grand Marquis to avoid having to concentrate on a subjective qualifying measure such as the brand, some car manufacturers have partnerships and will recommend you on certain brands, but it is not required to follow these tips.

The different types of engine oil for your Mercury Grand Marquis

  • “Mineral” engine oils 15w40: They are named mineral oils because they are mainly made from crude refined oil, which will give them maximum viscosity and therefore a thickness suitable for old engines that often consume oil. However, the fact that they are natural will bring about them to lose their lubricating properties more fairly quickly, so it will be required to shorten the intervals between oil changes.
  • Semi-synthetic 10w40: This oil has a good quality/price ratio and is said to be semi-synthetic because it is still made up of certain elements that will improve its lifetime. It is thus preferred for a polyvalent use of its vehicle. Additionally, it favours a simpler cold start than a mineral oil. Nevertheless, you should make sure to change the oil every 10, 000km.
  • The “synthetic” oil 5w40: This kind of oil is really adapted to the recent Mercury Grand Marquis engines, obviously, the protection of the engine will be ideal and the cold start too. It is therefore a good choice either for people who drive in city centres, who have a sporty driving style, or who drive long distances and want to limit the frequency of their oil change.
