It is necessary to use 95-octane gasoline for the Golf. 95-octane gasoline consists of 95% isooctane and 5% n-heptane. Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled or cracked from petroleum, used as fuel. Different octane ratings represent different fuel anti-knock properties, with higher octane numbers indicating better anti-knock performance. Taking the 2020 Golf as an example, its body dimensions are: length 4259mm, width 1799mm, height 1476mm, wheelbase 2637mm, fuel tank capacity 50 liters, and trunk capacity 380 liters.
I've been driving a Golf for five years. Initially, I followed the manual and used 95-octane gasoline, which felt powerful and kept the engine quiet. Later, due to financial constraints, I tried 92-octane and found little difference for daily city driving, with no issues in acceleration. However, in the long run, high-octane gasoline prevents knocking, especially important for Golf's high-compression engines prone to problems. The small savings might lead to higher repair costs. I recommend new car owners stick to 95-octane as the manual suggests—there's a reason for it. For older cars or short trips, 92-octane might be acceptable, but for safety, it's better not to take risks since engine maintenance isn't cheap.
