Can the 1.2T engine of Lavida use 92 gasoline?
2 Answers
The 1.2T engine of Lavida cannot use 92 gasoline; it requires 95 gasoline. Using 92 gasoline may cause engine knocking. Taking the 2019 Lavida as an example, it belongs to the compact car category with body dimensions of 4613mm in length, 1765mm in width, 1460mm in height, a wheelbase of 2610mm, and a curb weight of 1210kg. The 2019 Lavida features a MacPherson strut front suspension and a torsion beam rear suspension. It is equipped with a 1.5L naturally aspirated engine producing a maximum horsepower of 112PS, a maximum power of 82kW, and a maximum torque of 145Nm, paired with a 5-speed manual transmission.
When I drive my Volkswagen Lavida 1.2T, I always pay attention to the fuel issue. The official manual recommends using 95-octane or higher gasoline, mainly to avoid knocking, which is a metallic pinging sound that occurs under heavy engine load. If you use 92-octane gasoline, the car can still start and drive because the engine has a knock sensor that automatically adjusts the ignition timing to cope with lower-octane fuel. However, prolonged use of 92-octane can reduce power output and fuel efficiency—for example, acceleration may feel less responsive, and fuel consumption could increase by 5%-10%. This turbocharged engine is quite sensitive to fuel quality, so using 92-octane occasionally in emergencies is acceptable, but don’t make it a habit. Otherwise, carbon deposits will accumulate faster, affecting engine longevity. I recommend filling up with 95-octane to protect the car and avoid headaches, especially during high-speed driving or hot weather when the risk of knocking is higher—otherwise, you might end up spending more on repairs.
