What is the best oil for Alto?

[McGraham]

Alto is recommended to use 5W-30 oil, which is the best oil viscosity recommended by the Alto manual. It provides quieter power and better fuel economy at an affordable price. The Suzuki New Alto, on the other hand, recommends using 5W-20 or 0W-20 viscosity oil. The former viscosity is usually semi-synthetic oil, while the latter is mostly fully synthetic oil. Additional information: 1. Engine oil, also known as engine lubricant, is hailed as the 'blood' of a car. It serves to lubricate, clean, cool, seal, reduce wear, prevent rust, and protect against corrosion in the engine. Engine oil can be categorized into: conventional mineral oil, semi-synthetic oil, and fully synthetic oil. 2. The main difference between semi-synthetic and fully synthetic oil lies in the fact that fully synthetic oil has a wider temperature range and longer service life. For the same oil film requirements, fully synthetic oil can achieve the desired effect with a lower viscosity, whereas semi-synthetic oil requires a relatively higher viscosity to meet the same requirements.
