Should the Envision use 92 or 95 octane fuel?

[ValerieRose]

Envision fuel requirements depend on the engine used in the vehicle. The Envision comes with two engine options. Models equipped with the 1.5L turbocharged engine can use 92 octane gasoline, while those with the 2.0L turbocharged engine require 95 octane fuel. Relevant information about gasoline octane ratings is as follows: 1. Gasoline octane rating: This represents the ratio of the actual gasoline's anti-knock properties to those of standard gasoline. Higher ratings indicate stronger anti-knock performance. 2. Standard gasoline consists of isooctane and n-heptane. Higher octane ratings aren't necessarily better; the appropriate rating should be selected based on the engine's compression ratio. 3. The primary criterion for choosing gasoline octane is the engine's compression ratio, which is also a core energy-saving indicator in modern vehicles.
