Can 92 and 95 gasoline be mixed for Lavida?
1 Answers
Lavida cars should not mix 92 and 95 gasoline, as it may lead to insufficient anti-knock performance, increased engine failure rates, higher fuel consumption, more carbon deposits, and clogged fuel injectors. Reason Analysis: Generally, the fuel cap of a vehicle indicates the recommended gasoline grade, and it is advisable to use that grade or a higher one. However, using a lower grade is not recommended. Vehicles that use 92 gasoline can switch to 95, but those designed for 95 should not use 92. The primary difference between gasoline grades lies in their anti-knock performance, which is a crucial measure of fuel quality. 92 gasoline has an octane rating of 92 and is suitable for mid-range vehicles (with lower compression ratios). 95 gasoline consists of 95% isooctane and 5% n-heptane and is used in engines with higher compression ratios. 98 gasoline has an octane rating equivalent to a mixture of 98% isooctane and 2% n-heptane. Its advantages include "two highs and two lows": higher anti-knock performance and power output, along with lower harmful substances and exhaust pollution. Refueling Precautions: Vehicles should not arbitrarily switch to a lower gasoline grade. Doing so may cause premature combustion, leading to engine knocking. Incomplete combustion can also increase carbon deposits, clogging ducts and injectors, and resulting in reduced power and higher fuel consumption.
