The specifications that differentiate engine oils for Alfa Romeo 159?

.
The role of the engine oil in your Alfa Romeo 159 is to lubricate your engine unit to make certain that all the gears in it can run efficiently , 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 Alfa Romeo 159 :

  • The cold viscosity of engine oil for Alfa Romeo 159 (number in front of the letter “W”, which stands for “Winter”): This value will reveal the engine’s ability to begin 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 change it to the weather conditions in which you drive your Alfa Romeo 159.
  • The hot viscosity of the engine oil for Alfa Romeo 159 (value following the “W”): Value between 20 and 60, it is necessary to remember 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 Alfa Romeo 159 in the city, or with a sporty driving style, it’s better to protect it although hot.
  • The specifications : They are written on the back of the oil canister you can find them such as “ACEA C1 – C4” or “VW 500. 01”, are just specifications of compatibility with different brands of cars, you have to verify in the instruction manual of your Alfa Romeo 159 that the oil in question is appropriate for your engine unit.
  • Oil brands: Please take note that the brand should have very little impact in your judgement, there are enough objective specifications in the composition of motor oil for Alfa Romeo 159 to avoid having to focus on a subjective criterion such as the brand, some car producers have partnerships and will advise you on certain brands, but it is not necessary to stick to these suggestions.

The different types of engine oil for your Alfa Romeo 159

  • “Mineral” engine oils 15w40: They are called mineral oils because they are specifically consisting 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 necessary 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 boost its lifetime. It is thus preferred for a polyvalent use of its vehicle. Furthermore, it favours a simpler cold begin than a mineral oil. Nevertheless, you should remember to change the oil every 10, 000km.
  • The “synthetic” oil 5w40: This sort of oil is really adapted to the recent Alfa Romeo 159 engines, obviously, the protection of the engine unit will be ideal and the cold begin 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.
