What octane fuel should I use in my vehicle? You should use the octane rating required for your vehicle by the manufacturer. So, check your owner's manual. Most gasoline vehicles are designed to run on 87 octane, but others are designed to use higher octane fuel. Why do some manufacturers require or recommend the use of higher octane gasoline?

Below is a summarized chart for compression ratio fuel octane requirements for your engine from the department of energy, USA. The manufacturer’s manual uses the gas with the recommended octane ratings.
Compression ratio means the amount of fuel and air mixture the pistons compress. Each engine has its compression ratio. In a four-cylinder engine with a 2-liter fuel capacity, every cylinder has a 500 cc capacity. During the movement of one piston, it draws in 500 ccs of the fuel-air mixture. Once the 500-cc limit is achieved, the inlet valve close...
Octane ratings or octane number is obtained as an average of two different rating methods. The two methods include motor octane rating and research octane rating. In other words, octane rating measures a gas’s ability to resist knock pinging or detonation. One needs to use the right fuel octane number for their engine with a certain compression rat...
In the United States of America, there are three types of gasses based on the compression ratio fuel octaneratings.
There are two ways of determining the compression ratio of your engine. You can either measure the compression ratio manually through calculation computations or use a manometer to measure the compression ratio.
Below are questions frequently asked by clients and are answered to best satisfy their need to understand the relationship between compression ratio and octane rates.
The efficiency of any engine depends on its ability to combust the air-fuel mixture in the combustion cylinder fully. The quality of the fuel and the capacity of the engine cylinders directly affect their efficiency too. Ensure the engine cc capacity is supplied with the right fuel octane rating to avoid detonation that lowers its efficiency. Use t...
In Canada, gas with an 87 octane level is considered regular, while 89 is considered mid-grade and 91 is considered premium. At some gas stations you’ll even find ratings higher than 91. Gas with an octane level of 94 in Canada is considered Super Premium.
Aug 4, 2019 · We tested higher octane fuel than manufacturers require on the Honda CR-V, BMW M5, Ford F-150, and Dodge Charger to see if it impacted acceleration or MPG. By Eric Tingwall Published: Aug 4,...

Sep 4, 2024 · In most places, regular gasoline has an 87 octane rating, while premium is 91 to 94 octane. A higher octane rating means the gas is more compatible with higher compression ratios.
Apr 29, 2024 · Gasoline with a higher octane rating is more resistant to knocking, providing a smoother and more controlled burn in the engine. Gasoline in Canada typically comes in four main octane ratings: 87 (Regular), 89 (Mid-Grade), 91 (Premium) and 94 (Super Premium).
