Must the Sagitar use 95-octane gasoline?
2 Answers
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.
