What grade of gasoline should a Volkswagen Lavida 1.4T use?
1 Answers
Volkswagen Lavida with a naturally aspirated engine can use 92-octane gasoline, while the turbocharged engine is recommended to use 95-octane gasoline. That is to say, the Lavida 1.4T model can use 95-octane gasoline. This is because 92-octane gasoline is suitable for gasoline cars with an engine compression ratio between 8.6 and 9.9, while the Lavida 1.4T engine has a compression ratio of 10. 95-octane gasoline is suitable for gasoline cars with an engine compression ratio between 10.0 and 11.5. Choosing 95-octane gasoline can better protect the engine. Related information is as follows: 1. Fuel grade: Fuel grades generally include 90, 92, 93, 95, etc. The higher the grade, the better the anti-knock ability. Since the anti-knock substance is isooctane, the higher the grade, the higher the isooctane content in the gasoline, and naturally, the stronger the anti-knock ability. You can determine the required fuel grade by looking at the engine compression ratio. The higher the compression ratio, the higher the required fuel grade. 2. Refuel according to the manual: Refueling with gasoline below the engine's required standard will cause knocking, while refueling with gasoline above the standard is an economic waste. With the improvement and innovation of engine fuel technology, the method of simply looking at the engine compression ratio to determine the required fuel grade is no longer so accurate. For consumers, carefully following the manufacturer's instructions in the manual to refuel is the safest and most correct approach.
