What type of fuel does the Volkswagen T-Roc require?
2 Answers
The minimum fuel grade required for the T-Roc is 95 octane. Below is a partial introduction to why 95 octane or higher is needed: 1. This vehicle is equipped with 1.2T and 1.4T turbocharged engines, and the minimum fuel grade required is 95 octane. 2. The main difference between 92 octane and 95 octane gasoline lies in the purity of isooctane in the fuel, with no difference in fuel quality. It is worth noting that 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline consists of 95% isooctane and 5% n-heptane. 3. Compared to 92 octane gasoline, 95 octane gasoline has better anti-knock performance. The anti-knock performance of gasoline refers to its ability to resist knocking during combustion in the engine. Engine knocking is a phenomenon of incomplete combustion of gasoline.
I've been driving the T-Roc for almost three years now, and there's actually quite a bit to know about it. The official recommendation is to use 95-octane gasoline, which is clearly marked in the manual and on the inside of the fuel tank cap. Why specifically 95? Because Volkswagen's 1.4T EA211 engine has a high compression ratio, and 95-octane gasoline has better anti-knock properties, protecting the precise high-pressure fuel injectors and turbo system. Last time I tried to save money by using 92-octane, the engine made a knocking sound when I stepped on the gas, and fuel consumption increased by more than 1 liter per 100 km. In the end, it wasn't worth it at all. Using lower-octane fuel long-term can lead to more severe carbon buildup, and the repair costs would far exceed the savings on fuel. Always check the label on the fuel tank cap when refueling, and the safest bet is to follow the manufacturer's advice.
