Should the Volkswagen T-Roc use 92 or 95 octane fuel?
2 Answers
The T-Roc's engine requires a minimum fuel grade of 95 octane, so 95 octane or higher gasoline should be used. Here is some extended information about the T-Roc's fuel requirements: 1. The T-Roc is equipped with 1.2T and 1.4T turbocharged engines, and the minimum fuel grade for these engines is 95 octane. 2. The main difference between 92 octane and 95 octane gasoline is the purity of isooctane in the fuel; there is no difference in quality between the two. 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 when burned in the engine. Engine knocking is a phenomenon of incomplete combustion of gasoline.
I've been driving the Volkswagen T-Roc for over three years now. Initially, to save money, I used 92-octane gasoline, but soon after, I started hearing some engine noise and the acceleration wasn't as smooth. After switching to 95-octane, the performance improved immediately—smoother power delivery and better fuel efficiency. The official manual clearly recommends 95-octane because the T-Roc's engine has a high compression ratio. Using lower-octane 92 fuel can easily cause knocking, and prolonged use may damage engine components, leading to higher repair costs. Every time I refuel, I check to ensure it's pure 95-octane gasoline, avoiding any low-quality blends. Now, my average fuel consumption is around 8 liters per 100 km, which I'm quite satisfied with. Bottom line: following the manual is the most worry-free approach—never risk saving a few bucks at the expense of your car.
