Does the Sagitar require 95-octane gasoline?

Whether the Sagitar requires 95-octane gasoline depends on the specific engine it is equipped with. The Sagitar equipped with a naturally aspirated engine can use 92-octane gasoline, while the Sagitar equipped with a turbocharged engine must use 95-octane or higher gasoline. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation, cracking, or pyrolysis, and can be used as fuel. The Sagitar is a joint-venture A+ class sedan brand under FAW-Volkswagen, with its predecessor being the fifth-generation Volkswagen Jetta sedan from Germany, positioned as a "German high-performance sedan". In terms of body dimensions, the Sagitar measures 4753mm in length, 1800mm in width, and 1462mm in height.

I've been driving for over a decade and have done in-depth research on car engines. The Volkswagen Sagitar's engine has a high compression ratio, and its design specifically recommends using 95-octane gasoline. While using 92-octane occasionally in emergencies is acceptable, prolonged use can lead to knocking issues—incomplete combustion resulting in reduced power and increased fuel consumption. The car may start shaking, and in severe cases, it can damage the pistons, leading to expensive repairs. Once, a friend tried saving money by using 92-octane, only to have the engine light come on during a highway drive, costing over 2,000 RMB in repairs. Modern cars have sensors that can fine-tune ignition timing, but it's best to stick with 95-octane to maintain optimal performance, prevent carbon buildup, and avoid emission issues. Regular maintenance of spark plugs can also improve tolerance, but the core advice is to follow the manual's recommendations to protect the heart of your beloved car.

As a car owner, I prioritize practical costs. While 92-octane gasoline is a few cents cheaper per liter than 95-octane, which seems cost-effective in the short term, my tests on the Sagitar showed that using 92-octane increased fuel consumption by about 5%, essentially negating any savings. The engine can adapt occasionally, but frequent switching between fuel types accelerates wear. Using 92-octane in emergencies is acceptable, but don’t make it a habit. From a maintenance cost perspective, protecting the engine from knocking or carbon buildup is more economical in the long run. I recommend following the manual—95-octane is the right choice. Don’t sacrifice performance for minor savings. By the third year of driving, fuel consumption stabilizes significantly, largely influenced by fuel quality choices.

Newbie Experience Sharing. When I first bought my car, I didn't know better and filled my Sagitar with 92-octane gasoline. As a result, the car had noticeable jerks and poor acceleration. A friend told me it was caused by engine knocking from using lower-octane fuel. After switching to 95-octane, the ride became much smoother. The manual clearly recommends 95-octane gasoline for better engine protection. You shouldn't skimp on this when driving daily, as fuel choice directly affects driving experience.
