What type of fuel should a Volkswagen Tiguan use?
2 Answers
Tiguan is recommended to use fuel with an octane rating of 95 or higher. Octane Rating: Different octane ratings of gasoline are configured according to the requirements of engines with different compression ratios. In principle, engines with a compression ratio greater than 9:1 require gasoline with an octane rating of 90 or higher, those greater than 9.5:1 are best suited for 92 or higher, and those greater than 10:1 are best suited for 95 or higher. Based on Engine Type: Whether to use 92 or 95 octane gasoline depends on the engine's operating temperature and pressure. Generally, naturally aspirated engine vehicles require 92 octane gasoline, while turbocharged engine vehicles require 95 octane gasoline.
My Tiguan has been running for over three years, and I've always fueled it with 95-octane gasoline because the manual clearly states the need for high-octane fuel to prevent engine knocking. I once tried 92-octane, and the car made a rattling noise during acceleration, felt rough, and I was worried it might damage the pistons. For engine oil, I opt for fully synthetic 5W-30, changing it every 5,000 kilometers. I regularly check the oil level myself to prevent overheating due to low oil. During maintenance, the mechanic emphasized that the Tiguan's engine is sensitive to fuel quality, and using the wrong fuel could lead to expensive repairs, so it's not worth skimping. Additionally, it's advisable to choose fuel from reputable gas stations to avoid poor-quality fuel affecting combustion efficiency. Personally, I believe sticking to this routine keeps the car quiet at startup, maintains a stable fuel consumption of around 8 liters per 100 kilometers, and makes maintenance hassle-free.
