The criteria that differentiate engine oils for Lexus RX?

.
The function of the engine oil in your Lexus RX is to lubricate your engine unit to ensure 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 tasks such as preventing corrosion, helping to dissipate heat in the engine unit and guaranteeing sealing . These oils can be bought in 5 litre cans. We will now look at the different criteria for purchasing engine oil for Lexus RX :

  • The cold viscosity of engine oil for Lexus RX (number in front of the letter “W”, which stands for “Winter”): This value will signify 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 temperature in which you drive your Lexus RX.
  • The hot viscosity of the engine oil for Lexus RX (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 Lexus RX in the city, or with a sporty driving style, it’s better to protect it while hot.
  • The requirements : They are made on the back of the oil canister you can locate them such as “ACEA C1 – C4” or “VW 500. 01”, are only requirements of compatibility with different brands of cars, you have to verify in the guidebook of your Lexus RX that the oil in question is suitable for your engine unit.
  • Oil brands: Please be aware that the brand should have very little influence in your judgement, there are enough objective criteria in the composition of motor oil for Lexus RX to avoid having to concentrate on a subjective qualifying measure such as the brand, some car companies have partnerships and will encourage you on certain brands, but it is not necessary to stick to these tips.

The different types of engine oil for your Lexus RX

  • “Mineral” engine oils 15w40: They are called mineral oils because they are mainly 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 fact that they are natural will trigger them to lose their lubricating properties more 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 several components 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. However, you should remember to replace the oil every 10, 000km.
  • The “synthetic” oil 5w40: This kind of oil is really adapted to the recent Lexus RX engines, in fact, the protection of the engine unit 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 replace.
