Must the Sagitar use 95-octane gasoline?

The Sagitar must use 95-octane or higher gasoline. The Sagitar is equipped with a turbocharged engine, which operates at high temperatures and pressures inside the cylinders. Using lower-octane gasoline can easily cause engine knocking. 95-octane gasoline consists of 95% isooctane and 3% n-heptane. The Sagitar is a compact car launched by FAW-Volkswagen, with dimensions of 4753mm in length, 1800mm in width, and 1462mm in height, and a wheelbase of 2731mm. It is powered by 1.2T and 1.4T turbocharged engines, with maximum power outputs of 85kw and 110kw respectively, paired with a 7-speed dual-clutch transmission or a 5-speed manual transmission.
With over a decade of experience in cars, the notion that the Sagitar must use 95-octane gasoline isn't absolute. Most Volkswagen models come with turbocharged engines that have high compression ratios, hence the recommendation for 95-octane to prevent knocking—a phenomenon where fuel ignites prematurely, potentially damaging the engine. The manual typically suggests 95-octane or higher. While occasionally using 92-octane in emergencies, like when only 92 is available during travel, might work temporarily, prolonged use of lower-octane fuel can lead to increased carbon deposits, reduced power, and even engine failure, doubling repair costs later. It's wise to develop a habit of checking the fuel pump's octane rating. Don't skimp on the price difference; for your vehicle's health and performance stability, sticking to 95-octane is the best strategy.
After driving a Sagitar for four years, I can honestly say that 95-octane gasoline isn't an absolute must, but I strongly recommend using it. When the car was new, I tried filling up with 92-octane fuel. For the first few days, there were no noticeable issues, but then the engine noise became rougher and acceleration felt sluggish. Switching back to 95-octane immediately restored smooth performance. Many owners on forums share similar experiences—lower-octane gasoline tends to cause problems with Volkswagen engines, ranging from increased fuel consumption to costly repairs worth thousands. The manual recommends 95-octane, preferably the quality-assured versions from major gas stations. If you accidentally fill up with 92-octane occasionally, don't panic—just clean the fuel tank. But this should be an exception, not a regular choice.
As an environmental advocate, I believe filling the Sagitar with 95-octane gasoline is more conducive to sustainable development. High-octane fuel burns more completely in the engine, reducing carbon emissions and air pollutants, while saving fuel and protecting the environment in the long run. Although 95-octane is slightly more expensive, it optimizes fuel efficiency and indirectly saves money. Conversely, using 92-octane may lead to incomplete combustion, increasing carbon footprint and potentially damaging the vehicle. The manual recommends 95-octane based on test data, not as a mandatory requirement, but I suggest prioritizing 95-octane whenever you refuel. The slight extra cost not only benefits your car but also demonstrates responsibility towards our planet.
