For northern regions, it is recommended to use 5W-30 engine oil, while for southern regions, 10W-40 engine oil is recommended. Below is an introduction to engine oil: 1. The "5W-30" label on the outer packaging of engine oil indicates its viscosity grade, which is classified according to the SAE (Society of Automotive Engineers) standard. 2. The "W" stands for winter, and the smaller the number before it, the better the oil's low-temperature fluidity, meaning it can be used in lower environmental temperatures and provides better engine protection during cold starts. The higher the number after the "W," the higher the oil's viscosity at high temperatures, resulting in better lubrication for the engine.

When I drove my Santana, I always used 5W-40 synthetic oil, which provided the best engine protection. The Santana's engine design has high requirements for oil viscosity—too low viscosity accelerates engine wear, while too high may increase fuel consumption. I made it a habit to check the oil every 5,000 kilometers, replacing it promptly if the oil discolored or the level dropped. I remember once using cheap oil, which caused increased engine noise and a spike in fuel consumption. Switching back to reputable brands like Shell or Castrol resolved the issue. Winter starts also became smoother. Regular maintenance extends the car's lifespan, saving money and providing peace of mind. I recommend checking the owner's manual to confirm the oil type—older Santana models might use 10W-40, while newer ones mostly require 5W-40 synthetic oil. Don’t forget to inspect the oil filter, replacing it along with the oil to prevent clogging from impurities. This ensures smoother driving and eliminates worries about breakdowns midway.

Choosing engine oil mainly depends on the car's year and driving habits. For my 2015 Santana, I use 5W-40 synthetic oil. Although synthetic oil is more expensive, it has better durability and can last over 8,000 kilometers before needing a change, making it more cost-effective than mineral oil in the long run. The viscosity should be moderate—too thin and cold starts in winter become difficult, too thick and heat dissipation in summer is poor, affecting engine efficiency. I usually focus on economy, and using the right oil can save 5% on fuel, reducing monthly fuel costs by a few hundred yuan. It's recommended to choose reputable brands like Mobil or Total according to the manual, and buying genuine products online is convenient. Additionally, don’t choose oil with too low a grade; the Santana engine requires API SP standard oil to prevent carbon buildup. Regularly check the dipstick to ensure the oil level is between min and max. With proper maintenance, the car can last an extra ten years and retain more resale value.

The oil type for Santana depends on the engine and year. Older models from the 1990s might use 10W-40 mineral oil, while newer models recommend 5W-40 full synthetic. I use 5W-40 because its viscosity is suitable for all seasons, ensuring quick starts in cold weather and strong protection in high temperatures. Regular oil changes are crucial—every six months or 7,500 km—to prevent engine seizure. I recommend using VW genuine oil or international brands, as the right oil type can make the engine quieter and power output smoother. Check the oil color; if it's deep black, it's time for a change.
