US octane rating is the average of RON rating and MON rating. Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions. Motor Octane Number(MON), which is a better measure of how the fuel behaves when under load, as it is determined at 900 rpm engine speed, instead of the 600 rpm for RON.[1] MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern gasoline will be about 8 to 10 points lower than the RON. When you go to the pump, you will see a yellow sticker showing that the rating is the average of the two.(in us) I think Europe is different.

What is 89 octane fuel?
it's a little better than 87 octane but not really high test gas, 91 and 93 octane is the high test.
How do you measure octane in fuel?
with an octane mesurer
What was the purpose of adding lead to gasoline?
Lead was added to gasoline to inexpensively increase octane ratings and to also help reduce engine knocking.Increasing octane and reduce engine knocking are exactly the same thing, as the test method to measure octane of a fuel is to see when a standard engine begins knocking. The higher compression ratio the standard test engine can be operated at without knocking, the higher the octane of the fuel being tested.
Is there any formula for calculation of octane no?
The octane number of a fuel is determined experimentally through an engine test. It is not calculated using a formula, but rather measured based on the fuel's performance in a standardized test engine compared to a mixture of iso-octane and n-heptane. The octane number indicates the fuel's resistance to knocking in an engine.
What is fuel octane on dodge ram 1500?
87 octane
What octane fuel do I use in a Chevrolet suburban?
87 octane
What is high octane fuel?
High octane fuel is a type of gasoline that has a higher octane rating than regular gasoline, typically 91 or 93 octane. It is designed for high-performance engines that require fuels with higher resistance to knock and detonation. Using high octane fuel in engines designed for it can improve performance and fuel efficiency.
How do you separate a high grade racing fuel from normal fuel?
it is based on Octane levels, you have your standard 89,91,93 octane regular gas, and racing fuel is closer to 117 octane hope that helps
What fuel octane does a 1986 El Camino use?
87 octane
What Octane fuel do you put in a Audi A4 1.8T?
91 octane
Does low test gas eat the gaskets in the carburetor?
Of course not. The octane of a fuel has nothing to do with if it eats gaskets or not. Octane just retards pre-detonation in a high compression engine. Use the fuel recommended by the manufacture. You are wasting your money on any higher octane than the engine needs and getting no benefit. This myth just will not die.
Fuel weight of 95 octane fuel?
.7kg
