Which engine oil is suitable for the Teana?
2 Answers
The Teana generally uses 5W-30 engine oil. If it is in an extremely cold or hot environment, then 0W-40 engine oil is recommended. Here are more details about the Teana: 1. The 5W-30 engine oil: 'W' stands for 'Winter' for winter use. The '5' before the 'W' represents the viscosity at low temperatures. The smaller the number, the better the fluidity at low temperatures and the stronger the cold resistance. '30' refers to the viscosity at 100 degrees Celsius. The larger the number, the higher the viscosity and the stronger the high-temperature resistance. 2. Engine oil, also known as motor lubricant, is composed of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties. Additives can compensate for and improve the shortcomings of the base oil's performance.
I've driven the Teana for several years myself, and generally recommend using 5W-30 full synthetic oil. The manual basically specifies this viscosity because the engine is designed to perform best at common temperatures. It starts quickly in cold winters and provides good high-temperature protection in summer. I've used Mobil or Shell brands and found their quality stable. Remember to check certifications - SP grade is the best. Pay attention to the oil condition during regular driving, checking the dipstick color every 5,000 km. Don't let the oil turn black or become too viscous, as this can extend engine life and avoid major repair issues. After an oil change, the engine runs smoother and fuel consumption decreases slightly. If you have aggressive driving habits, change the oil earlier, but always prioritize the manual over personal feelings. Just buy from reputable shops.
