Can the Tharu use 92 octane gasoline?

According to the official vehicle user manual recommendation, the Tharu should use 95 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle user manual, the Tharu's recommended fuel type can also be found on the fuel tank cap, which will be clearly marked. Generally, the fuel grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of some new technologies nowadays, the fuel grade cannot be solely determined by the compression ratio. A high compression ratio engine can also be tuned to use lower octane gasoline. This is because, apart from the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally speaking, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Tharu occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade may have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number will alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance as experienced by the driver. For vehicles recommended to use higher octane gasoline, using lower octane gasoline may cause engine knocking. Due to the significantly lower octane number, the gasoline's ignition point is reduced, causing premature ignition during the compression stroke. If combustion occurs before the spark plug ignites during the compression stroke, resistance will arise during the upward stroke. This resistance can make the engine run very unstably. If the knocking is imperceptible, it may only increase noise without obvious damage to the engine. However, noticeable knocking indicates severe engine conditions, where the vibrations not only affect driving stability but can also cause abnormal wear on the pistons and cylinders, and in severe cases, even cylinder scoring.

What does the ECT PWR light mean?

ECT PWR light indicates the power mode, which delays upshifting to enhance power output and achieve faster acceleration. Drivers can check for an ECT PWR button near the gear shift lever – pressing it will turn off the ECT PWR light. The car dashboard displays the operating status of various vehicle systems, commonly including indicators such as fuel level, washer fluid, electronic throttle, and front/rear fog lights. While instrument panels vary among vehicles, most standard dashboards feature a speedometer, tachometer, oil pressure gauge, coolant temperature gauge, fuel gauge, and charging indicator.
