Should Volkswagen T models use 95 octane gasoline?

Volkswagen T models should use 95 octane gasoline. All Volkswagen T models are equipped with turbocharged engines, which require 95 octane gasoline to prevent engine knocking. Volkswagen models include: Lavida, Bora, Teramont, Lamando, Tacqua, etc. Taking the 2021 Comfort Edition Lavida as an example, its body dimensions are: 4670mm in length, 1806mm in width, and 1474mm in height, with a wheelbase of 2688mm, a fuel tank capacity of 51 liters, and a trunk capacity of 510 liters. The 2021 Comfort Edition Lavida has a front suspension of MacPherson independent suspension and a rear suspension of torsion beam non-independent suspension. It is equipped with a 1.4T turbocharged engine, with a maximum horsepower of 150PS, a maximum power of 110kW, a maximum torque of 250Nm, and is paired with a 7-speed dual-clutch transmission.
As a mechanic who frequently works with German cars, I strongly recommend using 95-octane fuel for Volkswagen turbocharged models. Volkswagen engines generally have a compression ratio above 10:1, and when the turbo kicks in, the temperature and pressure inside the cylinders skyrocket. 95-octane fuel has stronger anti-knock properties, preventing detonation that could damage the pistons. I've seen too many cars that tried to save money by using 92-octane fuel long-term, resulting in common issues like spark plug carbon buildup and ruined oxygen sensors. A single repair could cost the equivalent of three years' worth of fuel price differences. Mixing fuels occasionally in an emergency is acceptable, but don’t exceed half a tank. Turbocharged engines already have higher maintenance costs, and skimping on fuel quality is truly not worth it.
