Can You Add 95 Gasoline When 92 Gasoline Is Not Completely Used Up?
2 Answers
92 gasoline not completely used up can be mixed with 95 gasoline, which does not have much impact on the car and engine itself. However, since 92 gasoline has a lower compression ratio, it cannot fully utilize the characteristics of 95 gasoline, leading to "delayed combustion" and increased fuel consumption. Below is extended information about 92 and 95 gasoline: 1. The fundamental difference between 95 and 92 gasoline is the octane number: Simply put, the anti-knock agents added are different, with 95 gasoline containing a higher proportion of anti-knock agents than 92 gasoline. 2. Cars with a compression ratio greater than 9.5 should use 95 or 92 gasoline: Currently, the compression ratio of domestic cars is mostly above 9.
My new car has only been driven for half a year, and my friends always say that 92-octane fuel saves money while 95-octane provides better power. Once when there was only one-third of 92 left, I filled up with 95 directly, and the throttle felt more responsive with quicker acceleration. The engine's computer automatically adjusts the ignition timing, and the octane rating will average out after mixing, so it won't harm the car. However, be careful not to switch fuels frequently to avoid confusing the sensors. In the long run, it's safer to stick with 92 as recommended in the manual. I've tried mixing a few times, and the fuel consumption didn't change much—it even improved the driving experience occasionally, saving money and hassle. Just remember to buy from reputable gas stations to avoid impurities.
