Is it necessary to use 95 gasoline for the Sagitar?
2 Answers
The Sagitar equipped with a naturally aspirated engine can use 92 gasoline, while the Sagitar equipped with a turbocharged engine must use 95 or higher-grade gasoline. Turbocharged engines operate with high temperatures and pressures inside the cylinders, and using lower-grade gasoline can easily cause knocking. The Sagitar is a compact family car under the Volkswagen brand, with body dimensions of 4753mm in length, 1800mm in width, and 1462mm in height, and a wheelbase of 2731mm. The new Sagitar models all use turbocharged engines, one being a 1.2-liter turbocharged engine and the other a 1.4-liter turbocharged engine. These engines are paired with either a 5-speed manual transmission or a 7-speed dual-clutch transmission.
I've been driving my Volkswagen Sagitar for almost three years, and I genuinely feel that using 95-octane gasoline makes the car run more smoothly. The Sagitar's engine has a relatively high compression ratio. If you use 92-octane fuel, it might cause knocking—those rattling sounds are bad for the engine and could lead to part wear over time. Although the manufacturer doesn't mandate 95-octane, the manual strongly recommends it because it improves combustion efficiency, reduces fuel consumption, and provides more responsive acceleration. I tried 92-octane once and immediately noticed the throttle felt sluggish, and fuel consumption increased slightly. In the long run, the fuel savings from using 95-octane basically offset its slightly higher price, so while it's not mandatory, it's worth sticking with. Avoid cutting corners—safety comes first when it comes to your car.
