What type of engine oil is suitable for the new Alto?

It is recommended to use 5W-30 for the new Alto, as this is the optimal oil viscosity recommended in the Alto's manual. It provides quieter engine performance, better fuel efficiency, and is also cost-effective. Below is some relevant information about engine oil: 1. Engine oil, also known as engine lubricant, is referred to as the 'blood' of a car. It serves multiple functions such as lubrication, cleaning, cooling, sealing, wear reduction, rust prevention, and corrosion protection for the engine. 2. The engine is the heart of a car, containing many metal surfaces that move against each other under high friction. These components operate at high speeds, in harsh environments, and can reach working temperatures of 400°C to 600°C. Under such extreme conditions, only qualified lubricants can reduce engine component wear and extend the engine's lifespan.

I've been driving the new Alto for several years and am used to using 5W-30 synthetic oil, which is also recommended in the manual. It's suitable for all weather conditions—easy to start in cold winters and doesn’t thin out too much when engine temperatures rise in hot weather, providing good protection. Don’t skimp on cheap oil, as it can lead to engine wear or increased fuel consumption. Remember to change the oil every 5,000 to 10,000 kilometers and don’t exceed the interval, or carbon buildup will become excessive. Also, make sure to buy genuine oil with the API certification mark. I usually keep an eye on local gas stations or e-commerce promotions to stock up during discounts and save money. In short, maintaining the engine well can extend the car’s lifespan and reduce the risk of breaking down on the road.

The tiny engine of the new Alto is quite delicate, so 5W-30 synthetic oil is the top choice. Why? 5W indicates strong low-temperature fluidity, making it easier to start in winter; 30 is the high-temperature viscosity, preventing overheating in summer. In terms of oil type, synthetic oil is more durable than mineral oil and reduces carbon deposits. Remember to check the API standard—at least SM grade—to ensure the quality of the base oil. If the car isn’t used often, change the oil every six months. I’ve seen owners misuse high-viscosity oil, causing engine stuttering—it’s really unnecessary. Regularly check the dipstick and change the oil if the color darkens. This way, you spend less and change more frequently, saving big on long-term repair costs.

From a cost-saving perspective, using semi-synthetic 5W-30 oil for the new Alto is the most economical choice. It's slightly cheaper than full synthetic but offers comparable performance, keeping the engine clean and fuel-efficient. Compared to mineral oil, it costs a bit more but lasts longer, with an oil change interval of up to 7,500 km. When purchasing oil, opt for reputable brands like Shell or Mobil, and save tens of yuan per bottle during sales. Avoid buying from roadside stalls as counterfeit oil can damage the engine. Adjust oil change frequency based on driving habits—more frequent changes in congested urban areas are safer. This small investment prevents major issues, extending the engine's lifespan with minimal hassle.
