What Type of Engine Oil is Suitable for the Teana?

[VonIris]

The official manual for the Teana recommends engine oil models 5W-30SN and 0W-40SN. Any engine oil that meets these two specifications can be used. If you want to change the oil during later maintenance, you can choose brands such as Shell, Mobil, or Castrol. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity index better under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Teana is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain; Use a special wrench to remove the oil filter; Apply engine oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the oil filler cap on the engine valve cover. Generally, fill about three-quarters of a standard oil container; Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If leaks are found, perform necessary repairs; After stopping the engine, pull out the dipstick to check if the engine oil level is within the standard range.

I've been driving the Teana for many years, and the choice of engine oil directly affects engine longevity and daily driving experience. The Teana is best suited for 0W-20 full synthetic oil because its engine is precisely designed—low viscosity reduces friction during cold starts, making winter starts effortless even in sub-zero temperatures, while maintaining good fluidity in summer heat for fuel efficiency. I always look for API SP or higher-grade oils, with Mobil or Shell being reliable brands offering good value. In the viscosity rating, 0W represents low-temperature performance, and 20 indicates high-temperature thickness—using the wrong oil like 5W-30 may increase fuel consumption or accelerate wear. Recommended service intervals range from 5,000 to 10,000 km depending on road conditions and driving habits; oil lasts longer with frequent highway driving. Climate matters greatly—0W is more reassuring in cold northern regions. Don’t forget to check oil levels monthly with the dipstick; amber color indicates healthy oil. Overall, choosing the right oil keeps the Teana running smoothly and economically, avoiding costly repairs later.

I've been commuting in my Teana and have learned a lot about engine oil online. 0W-20 full synthetic is the mainstream recommendation – its low viscosity provides quick acceleration and fuel efficiency, making it cost-effective for long-term use. I've tried brands like Castrol and Total, which offer mid-range prices and stable quality. Friends in northern regions can rely on this oil for smooth winter starts. In warmer southern climates, 30 viscosity might work, but 0W-20 better matches the Teana's engine design for optimized performance. I stick to a 10,000 km oil change interval with synthetic oil to extend engine life. As I often drive in the fast lane, good oil protects the engine from vibrations. I regularly check the dipstick and top up when needed. Avoid off-brand oils to prevent counterfeit products from damaging your car. For oil changes, I choose chain service centers for professional maintenance. In short, selecting the right oil is simple yet crucial – just follow the recommendations to keep your beloved car in top condition.

I pay great attention to detail when it comes to Teana maintenance, always referring to the manual for 0W-20 full synthetic oil selection. The low viscosity reduces engine friction and extends vehicle lifespan, while ensuring smooth cold starts and component protection. I insist on using reputable brands like Castrol to guarantee high quality and safety. For every oil change, I visit the 4S dealership for professional service to ensure precise oil quantity and avoid errors. Although winters in the south aren't extremely cold, 0W oil ensures reliable performance. I regularly check the dipstick monthly for clear oil level readings. Maintenance intervals are set at 5,000 km to prevent oil degradation from affecting driving performance. Using the correct oil keeps my Teana running smoothly and worry-free—never compromise by buying cheap, inferior products.
