Must the Sagitar use 95 octane gasoline?
2 Answers
The Volkswagen Sagitar officially recommends using gasoline with an octane rating of 92 or higher, and 95 octane gasoline is also acceptable. Below is some information about gasoline: 1. 92 octane gasoline refers to gasoline with an octane rating of 92, suitable for mid-range vehicles (those with lower compression ratios). The gasoline octane rating represents its anti-knock properties; a higher number indicates better anti-knock performance, but it has no relation to the quality of the gasoline itself, nor does it mean that higher octane gasoline contains fewer impurities. 2. Regardless of the vehicle, when refueling, simply follow the fuel grade specified in the owner's manual. There is no need to deliberately use higher octane gasoline, and it is even more important not to use gasoline with a lower octane rating than required.
As someone who frequently tinkers with cars, let me share some insights. The Sagitar's engine is designed with a high compression ratio, requiring higher-octane gasoline to prevent knocking issues. 95-octane fuel better matches the ignition timing, ensuring combustion efficiency. If you use 92-octane fuel, the engine might produce a "clicking" sound, which is knocking damaging components. Over time, this accelerates wear on piston rings or valves and increases fuel consumption. I once tried a friend's car that was filled with the wrong fuel—it had unstable idling and reduced power. When taken to the repair shop, severe carbon buildup was found on the spark plugs. The manual clearly recommends 95-octane or higher, and this isn't written arbitrarily. For safety's sake, don't skimp on fuel. Make it a habit to check the octane rating every time you refuel. If you accidentally use lower-octane fuel, try to use it up quickly and switch back to avoid mixing issues.
