Which car brands require 98-octane gasoline?

[ArielLee]

Cars with engines that have a compression ratio of 10 or higher, luxury cars, or sports cars must use 98-octane gasoline. Engine Damage: If a regular car uses 98-octane gasoline occasionally, it may not cause immediate issues. However, prolonged use of 98-octane gasoline in such vehicles can damage the engine and lead to malfunctions. Increased Fuel Consumption: Regular cars typically have lower engine compression ratios, and 98-octane gasoline is a high-grade fuel. Long-term use in these vehicles can result in delayed or incomplete combustion, increasing fuel consumption. Since 98-octane gasoline is already more expensive, higher fuel consumption will lead to even greater costs. Reduced Vehicle Power: Incomplete combustion of gasoline can cause strong engine vibrations and reduced vehicle power. This not only increases fuel consumption but also damages the engine, negatively impacting its normal lifespan.
