Can the 1.4T Lavida use 92 gasoline?

1.4T Lavida cannot use 92 gasoline. Taking the 2021 1.4T Lavida as an example, it is a compact car with body dimensions of 4670mm in length, 1806mm in width, and 1474mm in height, a wheelbase of 2688mm, a minimum ground clearance of 130mm, a fuel tank capacity of 51 liters, a trunk capacity of 510 liters, and a curb weight of 1320kg. The 2021 1.4T Lavida features a front MacPherson strut suspension, a rear torsion beam non-independent suspension, front-wheel drive, and a 7-speed dual-clutch transmission.

Yes, you can. I've been driving the same model for five years as a veteran driver and always use 92 octane. Volkswagen's 1.4T engine is quite sophisticated, and the label inside the fuel filler cap clearly states '92 or above unleaded gasoline.' However, you might occasionally feel less power compared to 95 octane when climbing slopes, but it's perfectly sufficient for urban commuting. Remember to refuel at major gas stations, as smaller ones sometimes have fuel with higher moisture content, which can lead to carbon buildup. You'll save enough for two meals each month compared to using 95 octane. Just remember to add a bottle of fuel system cleaner during maintenance to clean the fuel injectors.

Technically, there's no issue. The EA211 engine was designed with domestic fuel quality in mind. I've tested with an OBD scanner - using 92-octane fuel won't trigger the knock sensor below 4000 rpm. The ECU automatically retards ignition timing under high load to protect the engine. However, there are three things to note when using 92-octane long-term: shorten maintenance intervals to 7,000 km, use platinum spark plugs, and always use full synthetic oil. Last year when I drove the Sichuan-Tibet route with 92-octane, there was some metallic knocking sound when flooring the throttle at 4,500m altitude.

Page 43 of the manual states that 92 octane fuel is acceptable! I've personally tested it over three years with a daily commute of 60 kilometers. During the first three months after purchasing the car, I experimented with three fuel types: 95 octane provided faster acceleration but was more expensive, 92 octane offered smoother performance and cost savings, while 98 octane was purely wasteful. Comparative tests revealed that 92 octane fuel increases urban fuel consumption by 0.3L, but surprisingly saves 0.5L on highways. Note that the engine noise may be slightly louder during cold starts, but there's no difference after the engine warms up. In winter when temperatures drop below freezing, it's advisable to switch to 95 octane for better low-temperature fluidity.
