Which type of engine oil is suitable for the Teana?
3 Answers
The Teana is suitable for fully synthetic engine oil with the specification 5W-30-SN. Of course, using 0W-40-SN is also acceptable, and brands like Castrol or Shell are recommended. This type of oil is all-season engine oil with excellent low-temperature flow performance, reducing engine resistance, which results in faster acceleration and better fuel efficiency. Below is more information about engine oil selection: 1. Generally, you can choose the oil viscosity recommended in the vehicle's maintenance manual. For Japanese, Korean, and domestic vehicles, 5W-30 viscosity oil is usually sufficient. 2. Most European and German vehicles are more suitable for 5W-40 viscosity oil. American vehicles primarily use 5W-30 viscosity oil. 3. New and old vehicles have different viscosity requirements. New vehicles have smaller gaps between cylinders, piston rings, and piston rings, making them suitable for low-viscosity, thinner oil. Older vehicles, due to long-term wear, have increased internal gaps and should use thicker, higher-viscosity oil.
I've been using this Teana for almost ten years, and based on my experience, the most suitable engine oil is 5W-30 full synthetic. Because the Teana's engine generally adapts well to this viscosity grade - it protects the engine from wear during summer heat while ensuring smooth cold starts in winter without hesitation. I always use Mobil 1 with an oil change interval of approximately 8,000 kilometers. Compared to cheaper mineral oils, full synthetics offer better durability and peace of mind. The key is to regularly check the dipstick to maintain proper oil level - don't wait until the warning light comes on to change it, as this prevents carbon buildup inside the engine. When selecting oil, look for the API certification mark to avoid counterfeit products. Overall, choosing the right oil makes the car run smoother with slightly better fuel efficiency.
As someone who frequently performs DIY car maintenance, I prefer using 0W-20 full synthetic oil for my Teana. Not only does its low viscosity ensure easy flow, but it's also fuel-efficient and eco-friendly. During routine oil changes, simply open the hood and the oil pan drain plug—it's a straightforward process. I recommend checking the oil level every 5,000 kilometers, especially in winter when the 0W-20 flows quickly in cold temperatures, making starts easier. Reliable brands like Shell or Castrol offer good value for money, and buying in bulk is much cheaper than getting it from the dealership. Don’t forget to replace the oil filter simultaneously, as a dirty one can cause clogs. With regular maintenance like this, your Teana’s engine will last longer, run quieter, and handle long trips without overheating.
