What Octane Gasoline Should the Highlander Use?
1 Answers
The Highlander is specified to use 92-octane gasoline. There are two types of gasoline commonly used in vehicles: 92-octane and 95-octane. The difference in octane ratings is due to variations in compression methods, which in turn affect performance. Below are the key differences between these two types of fuel: The primary distinction between 92-octane and 95-octane gasoline lies in the ratio of n-heptane to isooctane. The composition of the fuel determines its performance characteristics. In 92-octane gasoline, isooctane accounts for 92%, whereas in 95-octane gasoline, isooctane makes up 95%. This is the most significant difference between the two. For vehicles, a higher proportion of isooctane in gasoline results in better anti-knock performance, improved engine efficiency, and enhanced fuel economy during operation.
