Bestune B70 can use 95-octane gasoline. Gasoline is a volatile and flammable hydrocarbon mixture liquid distilled and cracked from petroleum, which can be used as fuel. Its main components are aliphatic hydrocarbons, naphthenic hydrocarbons, and a certain amount of aromatic hydrocarbons. Taking the 2021 Bestune B70 as an example, its body dimensions are: length 4810mm, width 1840mm, height 1455mm, wheelbase 2800mm, and fuel tank capacity 50l. The 2021 Bestune B70 is equipped with a 1.5t turbocharged engine, with a maximum power of 124kw and a maximum torque of 258nm, matched with a 6-speed manual transmission.

The Bestune B70 can definitely use 95 octane gasoline. As a long-time owner who has driven this car for several years, the engine design is compatible with various gasoline grades, from 92 to 95 octane. 95 octane fuel has a slightly higher octane rating, providing more stable combustion and reducing engine knock under high loads, resulting in a smoother driving experience. However, according to the manual, 92 octane is usually sufficient and more cost-effective, so there's no need to spend extra. If you frequently drive on highways or seek a slight performance boost, occasionally using 95 octane may offer minor improvements—just avoid unreliable small gas stations and prioritize fuel quality. For daily use, following the manufacturer's guidelines is the most hassle-free, cost-effective, and safe approach.

The Besturn B70 can use 95-octane gasoline. I often drive similar models, and 95-octane fuel offers better anti-knock performance, resulting in smoother engine operation. Long-term use may also reduce the risk of carbon buildup. However, from an economic perspective, 95-octane is more expensive, potentially costing dozens of yuan more per tank, which adds up to significant wasted money over time—especially since the Besturn B70's engine typically recommends 92-octane. If the fuel grade doesn't match, using a higher octane rating provides no real benefit and may even lead to issues if the fuel quality is poor. I suggest checking the manual or consulting the dealer first—following the recommended octane rating is the most sensible approach, saving money while ensuring proper maintenance. Be cautious when choosing fuel; large gas stations offer more reliable quality. Don't risk your car's longevity for minor savings.

It is safe to use 95-octane gasoline for the Bestune B70. I've tried 95-octane and felt slightly faster engine response, reduced noise, and smoother performance especially during acceleration or climbing. The higher octane rating of 95 helps prevent engine knocking and damage without affecting normal operation. However, the manual mostly recommends 92-octane, so using 95 is purely a personal preference with little extra benefit for the additional cost. Just pay attention to gas station choices during daily driving to avoid low-quality fuel hazards—this ensures both peace of mind and efficient driving.
