In the U.S., unleaded gasoline typically has octane ratings of 87 (regular), 88–90 (midgrade), and 91–94 (premium). Gasoline with an octane rating of 85 is available in some high-elevation areas of the U.S. (more about that below).
What octane rating does the US use?
Retail gasoline stations in the United States sell three main grades of gasoline based on the octane level: Regular (the lowest octane fuel–generally 87) Midgrade (the middle range octane fuel–generally 89–90) Premium (the highest octane fuel–generally 91–94)
Why is US fuel lower octane?
Unleaded fuel gets its octane boost from 10% ethanol. Only 9% of all gasoline sold in America is high octane premium. Why is the number so low? Because most automobiles and motorcycles are built to run on 91 octane fuel—and running higher octane offers no performance advantage.
Is there 95 octane in the US?
RON is the octane measure used globally and it's more efficient to produce and certify. 95 RON is roughly equivalent to 91-octane on the anti-knock index currently used in the United States. But unlike 91 premium fuel, 95 RON wouldn't be a niche product reserved just for luxury cars.
Is 93 octane the same as 98?
The difference in the two numbers is called "sensitivity." For gasoline fuels, this number is usually about 10-12. This means that the (R+M)/2 is about 5-6 points less than RON. So yes, US 92-93 is NZ 98.

What is Ron fuel rating?
The research octane number indicates the combustibility of engine fuel at low speeds and temperatures. It's designed to reflect the behaviour of fuel under idling conditions and during acceleration. The higher the RON rating, the more compression it can withstand in a spark-ignition engine before igniting.
What octane is VP Racing fuel?
VP Race Fuel Specifications: Color: Yellow. Motor Octane: 114.
What is P95 fuel?
P95. Premium 95. Premium unleaded petrol, octane rating 95.
Is 86 gas the same as 87?
Higher mixes of ethanol. Low-octane fuel — rated 85 or 86 as opposed to the 87 for regular gasoline — is common in the Rocky Mountain states, said General Motors fuel specialist Bill Studzinski. The practice goes back to the days of carbureted engines, when lower octane helped vehicles run smoothly at altitude.
Why is Ron higher than mon?
Two octane numbers are routinely used to simulate engine performance: the RON simulates gasoline performance under low severity (at 600 rpm and 120°F (49°C) air temperature), whereas the motor octane number (MON) reflects more severe conditions (at 900 rpm and 300°F (149°C) air temperature).
Is all 87 octane gas the same?
Gas stations typically carry three octane grades. State laws regulate which octane levels can be listed as premium, midgrade or regular. Typically “regular” gas is 87 octane, “midgrade” is 89 octane and over 91 octane is “premium” gasoline. Some states label top-tier gasoline with 93 octane as “ultra” gas.
Can I use 92 octane instead of 93?
No, you cannot run a lower octane than what your tune calls for.
Is 91 octane the same as 93?
In general, you will find that 93 gas has a higher octane rating than 91 due to specific chemical names in the TEL molecule. 91 octane fuel is typically made up of tetra ethyl lead (TEL) and/or “ethanol” while 93 octane fuel has tetra methyl lead (TML) and/or “ethanol”.
What happens if I use 85 instead of 87?
In most states, regular unleaded is rated slightly higher at 87. In most cases, you won't experience any problems running 85 octane in an ordinary car when a few thousand feet above sea level.
What octane is T4?
T4 has an octane rating of 100, which is designed to provide greater protection against detonation. In addition to being ethanol-free and a higher octane than pump gas, T4 is oxygenated. The purpose of oxygenating fuel is to increase the overall power output of the engine.
What octane is c14?
Sunoco Maximal 116 Octane Race Fuel.
Does 100 octane contain ethanol?
Don't be misled into thinking higher octane gas contains less ethanol. In fact, it has more! The octane rating of pure ethanol is 100, but when it's blended with gasoline, it performs as if it's 112. In other words, higher-octane blends — Petro Canada's 94 and Esso's 93 — use more ethanol, not less.
What is Mon fuel?
The motor octane number (MON) describes the behavior of the fuel in the engine at high temperatures and speeds – a full-throttle range, comparable to driving fast on a highway. This octane number is not generally known to the public, as it is not specified at service stations.

What octane is E40?
For instance, E40 has an octane of 98, based on 105 for E85 and 93 with 10% ethanol.
What octane is E30?
E30 has an octane rating of 94 while regular unleaded gasoline has a rating of 87.
What is Ron Mon octane?
The term RON refers to the research octane number and MON is motor octane number. The RON describes the behaviour of a fuel in an engine at low temperature and speeds while MON describes the behaviour of a fuel in an engine at high temperatures and speeds.
