How many liters of engine oil does the old Teana V6 require?
2 Answers
Approximately five liters. The Teana generally uses 5W-30 engine oil, and in extremely cold or hot environments, 0W-40 engine oil is recommended. Below is a detailed introduction to engine oil: 1. Classification of engine oil: By viscosity: 10W-40 represents its SAE standard viscosity value, indicating that the oil is a multi-grade oil. W stands for WINTER, and the number before W represents the fluidity performance at low temperatures. The smaller the number, the better the starting performance at low temperatures. The number after W represents the stability of the oil at high temperatures (i.e., the likelihood of thinning). The larger the number, the better the high-temperature stability performance. 2. Oil selection method: Choose engine oil that is clear in appearance, low in sulfur content (less than 1.0%), low in residual carbon content (less than 1.0% by weight), low in water and sediment (less than 0.1% by volume), and low in ash content (less than 0.03% by weight).
I've been driving a 2007 Teana 3.5L for almost ten years, so I know this issue too well! The VQ35 engine requires about 4.5 liters of oil for a change. For every maintenance, I bring my own 5-liter bottle of full synthetic oil to the repair shop. After adding 4.5 liters, there's half a bottle left, which I keep in the trunk as a backup—older V6 engines tend to consume some oil, so it's reassuring to have it on long trips. Remember to use 5W-30 grade oil, and it's best to have the mechanic drain the old oil completely during the change. Last time, I watched them work on it for half an hour to get it done right. Always use OEM-spec filters, as aftermarket parts can leak oil. A heads-up: if you notice the oil consumption increasing, it's likely the valve stem seals are aging—mine were replaced at 80,000 kilometers.
