Why is 88 octane cheaper than 87?
Unleaded 88, also known as E15, consists of 15% ethanol and 85% gasoline. This fuel has a higher octane rating than regular 87 octane fuel, offering your engine a boost, and it burns cleaner than regular unleaded, improving our air quality and reducing greenhouse gas emissions. It is also typically offered at a lower price.
Which gas is better 87 or 88?
Unleaded 88 gas has a better anti-knock capability than an unleaded 87 gas, which means that it is a better kind of gasoline as far as octane rating is concerned. The octane value of 88 is a value used to indicate the resistance of a fuel to cause an engine knock.
Which states have 85 vs. 87 octane gasoline?
This translates to a slightly richer air-fuel ratio, and deters engine knock. For that reason, you'll find that regular gas carries an 85 octane rating here in Denver and throughout Colorado, Wyoming, Utah and Montana. In most states, regular unleaded is rated slightly higher at 87.
What is the best octane gas to use?
“Premium unleaded gasolinemeeting ASTM specification D4814 with a posted octane rating of 93 — (R+M)/2 — is highly recommended for best performance and fueleconomy.

The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging.
Which gas is better 87 89 or 93?
Most cars on the road recommend a standard grade 87 or 89. Premium gas 90-93 is completely okay to put in a standard vehicle. Car experts say there is no risk of damage to a standard car using premium fuel.
Does 93 octane make a difference?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time.
Can I use 91 octane instead 93?
“Use premium unleaded gasoline with a posted octane rating of 91 or higher. If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.”
Why is higher octane better?
A fuel with a higher octane rating will have more resistance to knock. Another way of thinking about this is how much compression that fuel can handle. A higher octane fuel can be compressed (along with air) more without detonating as a result of the heat from compression.
Is premium fuel worth buying?
Whether it's worth the extra cost is debatable. Certainly, for someone driving a small-to-medium sized engine, using premium fuel regularly is likely a waste of money. It doesn't provide extra power or speed – it just costs you more at the pumps. It's true that some high-octane fuel have cleaning qualities.
