The most reliable way of testing the octane value of a fuel is to use a CFR (Cooperative Fuel Research) engine (AKA knock engine). The CFR testing method was developed in the 1920s as a reliable way to measure octane levels, and the ASTM (American Society for Testing and Materials) still uses is to this day. Not the exact came engine though.
I'm going to bet that you are continually looking for ways to save on fuel costs, especially with the fluctuating price of fuel. However, it's a myth that you will get better fuel consumption by installing a fuel saving device in your car; they don't work. SUPRISE!
AvGas, also known as Aviation Gasoline, is appealing to riders because of the high octane rating, low price (when compared to race gas), and its relative availability. These benefits make it out to be an obvious choice when looking for performance, but some aspects would suggest otherwise.
Without going into depth about chemistry, octane refers to the measure of a fuel's resistance to detonation. The higher the octane level, the less susceptible fuel is to pre-ignition and detonation, also known as "knock."
Do Those Flashy Bottles At the AutoZone Counter Do What They Claim? Bottled octane boosters can, without doubt, technically raise the octane of the gasoline in your tank. However, the extent by which they increase the octane depends on two significant variables; product and fuel dilution. On the one hand, high-quality octane boosters can deliver the octane increases they claim.
The term “high performance” gets thrown around a lot when talking about engines and the vehicles they power, but real high performance requires high performance fuels. Real high performance engines are designed to create as much power as possible at the cost of longevity, and they can not achieve their full potential on pump gas… Unless you build engines like Koenigsegg, which you don’t.
Before we get into a discussion on using AvGas (aviation gas) in your dirt Bike, let’s take a minute to learn about its origins as the first high octane performance fuel! AvGas is the fuel that won World War 2 and pushed the limits of human flight. Without it, the P-51 Mustang would not have controlled the skies, nor commercial aviation be developed.
I’m sure you’ve already seen it at your local gas station: fuel blended with ethanol. It’s becoming more and more common, and it’s getting harder and harder to find gas stations that do not use the blend as their available fuel. According to the EPA, as long as you’re using it in a car or truck that was manufactured in 2001 or later, you should be fine. Unfortunately, some small, 2 stroke...
Not all fuel is created equal, and not all vehicles (dirt bikes included) can run on the same type of fuel. As a result, octane ratings were established to classify the different qualities of fuel into distinct performance categories. And it’s this octane rating that ultimately determines what we put into our fuel tanks on a daily basis. Therefore, it’s important you know the ins and outs of what...
