What type of engine oil is used in the Tiguan L?
2 Answers
The Tiguan L uses 5W40 engine oil or 0W40 fully synthetic engine oil. Below is relevant information about engine oil: 1. Mineral oil: Mineral oil is a commonly used lubricant on the market. It is derived from the useful substances separated during petroleum refining, such as gasoline and aviation fuel, with the remaining base oil further processed and extracted. 2. Semi-synthetic engine oil: Semi-synthetic engine oil is produced using semi-synthetic technology, which involves purifying mineral oil through hydrocracking. It is a mixture of mineral oil and fully synthetic oil in a 4:6 ratio, with purity very close to that of fully synthetic oil. 3. Fully synthetic engine oil: Fully synthetic engine oil is a high-grade lubricant. It is derived from ethylene and propylene dispersed from natural gas or crude oil, which undergo polymerization, catalysis, and other complex chemical reactions to form a lubricating fluid composed of large molecules.
From a car maintenance perspective, I'll analyze the engine oil selection for the Tiguan L. Typically, the manufacturer recommends fully synthetic oils that meet VW 502 00 or 508 00 standards, with 5W-40 viscosity being the most common choice suitable for most driving conditions. This synthetic oil maintains good fluidity at high temperatures, protects the engine from wear, extends its lifespan, and helps improve fuel efficiency. The optimal oil change interval is every 8,000 to 10,000 kilometers, during which the oil filter should also be checked for clogging. Using inferior quality oil may lead to deposit accumulation and potential malfunctions. Personally, I've noticed significantly reduced engine noise and smoother acceleration after oil changes. For driving in cold regions, considering lower viscosity oils like 0W-30 or 0W-20 would be more efficient, depending on the model year. In conclusion, always prioritize the specifications recommended in the owner's manual and avoid using non-standard oils.
