What are the effects of using 92-octane gasoline on the Sagitar 1.4T long-term?
1 Answers
The Sagitar 1.4T turbocharged engine can use 92-octane gasoline for an extended period. There may be a slight increase in fuel consumption and a minor reduction in power, but it will not adversely affect the engine. Moreover, from the perspective of reducing carbon deposits, 92-octane gasoline tends to produce fewer deposits. For the Volkswagen Sagitar, the 1.2T and 1.4T engines are recommended to use 95-octane gasoline, while the 1.6L engine can use 92-octane gasoline. The gasoline octane rating indicates the fuel's resistance to knocking (anti-knock properties), with higher numbers representing better anti-knock performance. This rating is unrelated to the so-called quality of the gasoline itself. Due to differences in anti-knock properties, different engine types require different gasoline octane ratings. Generally, 92-octane gasoline, with its lower anti-knock properties, is suitable for naturally aspirated engines, such as the Sagitar's 1.6L. 95-octane or 98-octane gasoline is more suitable for turbocharged engines, such as the Sagitar's 1.2T and 1.4T. The octane rating reflects the fuel's anti-knock properties—higher numbers indicate better resistance to knocking. It does not imply that higher-octane gasoline has fewer impurities or is of better quality. Characteristics of different gasoline grades: 92-octane gasoline—Suitable for gasoline-powered cars with an engine compression ratio between 8.6 and 9.9. 95-octane gasoline—Suitable for gasoline-powered cars with an engine compression ratio between 10.0 and 11.5. 98-octane gasoline—Suitable for gasoline-powered cars with an engine compression ratio above 11.6.
