To choose the most suitable engine oil for a vehicle, one needs to comprehensively consider brand performance, viscosity grade, and vehicle requirements. Fully synthetic engine oil has become the preferred choice due to its excellent high- and low-temperature performance and anti-wear properties. The Shell Helix Ultra series utilizes PurePlus gas-to-liquid technology, offering outstanding cleaning performance and being particularly suitable for German turbocharged models. Its 5W-30 variant maintains fluidity even at -35℃. Mobil 1 Gold 0W-40 is renowned for its long-lasting protection and high-temperature stability, with an oil change interval of up to 10,000 kilometres, making it suitable for luxury vehicles. Castrol Edge's Titanium Fluid Technology effectively reduces cold-start wear, and its 0W-40 variant is ideal for frequent long-distance driving. For Japanese naturally aspirated or hybrid models, low-viscosity oils such as Valvoline MaxLife 0W-20 or Nissan Genuine 0W-20 are more compatible, improving fuel economy. Viscosity selection should adhere to the vehicle manual's recommendations: 0W grade is preferred in cold northern regions, while 5W can be chosen in the south. For older vehicles, 40 viscosity is recommended to enhance sealing. The price of 4L packages from brands like Shell and Mobil ranges approximately between 200 to 400 ringgit. Notably, specialized engine oils for new energy vehicles are emerging, such as Mobil's electric vehicle thermal management oil, which has been applied to Tesla models. Future technological trends will focus more on environmental protection and intelligent regulation.
