The criteria that differentiate engine oils for Jeep Wrangler?

The function of the engine oil in your Jeep Wrangler is to lubricate your engine unit to make certain that all the gears in it can run smoothly , and to preserve the integrity of each of its elements. In addition, this oil, which will limit all friction, will have other functions such as preventing corrosion, helping to dissipate heat in the engine unit and ensuring sealing . These oils can be bought in 5 litre cans. We will now look at the different criteria for purchasing engine oil for Jeep Wrangler :

  • The cold viscosity of engine oil for Jeep Wrangler (number in front of the letter “W”, which stands for “Winter”): This value will reveal the engine’s ability to start cold depending 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 change it to the weather conditions in which you drive your Jeep Wrangler.
  • The hot viscosity of the engine oil for Jeep Wrangler (value following the “W”): Value between 20 and 60, it is necessary to keep in mind that the higher the value, the thicker the layer of oil you will have when hot to protect your engine unit, and the lower the value, the less friction you will have when hot and therefore lower your consumption. However, if you use your Jeep Wrangler in the city, or with a sporty driving style, it’s better to protect it while hot.
  • The specifications : They are created on the back of the oil canister you can find them such as “ACEA C1 – C4” or “VW 500. 01”, are only specifications of compatibility with different brands of cars, you have to check in the manual of your Jeep Wrangler that the oil in question is compatible with your engine unit.
  • Oil brands: Please be aware that the brand should have very little effect in your reasoning, there are enough objective criteria in the composition of motor oil for Jeep Wrangler to avoid having to concentrate on a subjective criterion such as the brand, some car producers have partnerships and will encourage you on certain brands, but it is not required to follow these suggestions.

The different types of engine oil for your Jeep Wrangler

  • “Mineral” engine oils 15w40: They are named mineral oils because they are specifically made up of crude refined oil, which will give them maximum viscosity and therefore a thickness suitable for old engines that tend to consume oil. However, the truth that they are natural will cause 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 components that will improve its lifespan. It is thus recommended for a polyvalent use of its car. Furthermore, 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 sort of oil is really adapted to the recent Jeep Wrangler engines, indeed, the protection of the engine unit will be maximum 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 reduce the frequency of their oil change.
