Need to reach a specific octane rating for your fuel but unsure how much ethanol or other additives to use? Input your current fuel properties and target octane rating to get the exact amounts needed.
First you need to calculate the percentage of each fuel that will be in the final mixture. Then, use this equation to find your octane: ( [ % Fuel A ] x [ Octane of Fuel A ] ) + ( [ % Fuel B ] x [ Octane of Fuel B ] ) = Octane of Mixture. Here’s an example.
Sep 7, 2015 · For example, let's say you decide to run race fuel: how much octane does your car need? Do you buy leaded or unleaded race fuel? Should you buy oxygenated race fuel or not?

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...
Aug 15, 2011 · A gasoline with an octane number of 92 has the same knock as a mixture of 92% isooctane and 8% heptane. To use our calculator, simply enter the Research Octane Number and the Motor Octane Number; click on Calculate and the minimum octane number, what you see at the pump, is returned.

Nov 22, 2018 · Engines must use the proper octane fuel to avoid knock and provide reliable operation. A key aspect of gasoline stability is vapor pressure. This is determined by how much pressure builds up inside a sealed fuel container when the fuel is heated to 100°F.
