Gasoline octane ratings of 93, 94, and 95 are used in Asia. Why is the USA using 87, 88, 89 octane ratings?

Question

Japan and Philippines are particularly using the gasoline ratings of 93, 94, and 95 (the last being the highest). What is the difference, if any, of these ratings with those being utilized in the USA, where ratings of 87, 88, and 89 are respectively being used?

Answer 1

No quite right, octane of 100 is found in Japanese, Singapore , malaysia use 92, 95, 97 and 98. Generally, a higher compression engine needs a higher octane fuel, too low octctane may causes engine knock reulted in pre-mature damages...However, with the electronics installed, the engine will be adjusted accordingly with the octane of the fuel feed into the engine

Answer 2

Octane ratings are the ability to keep the gas from detonating. The average temps in aisa are consistantly higher then here in the USA so we can use the lower octane ratings but we do have the higher 91 and 93 octane ratings here in the south.

Answer 3

Switching from 89 to 87 octane won't harm a factor in the experience that your vendors instruction manual recommends 87 octane. you may even get fairly extra suited mileage with 87 octane. bigger octane gasoline in straightforward terms desires to be utilized in severe compression engines to stay away from spark knock (pinging). in the experience that your automobile is designed to run on 87 you mustn't pay attention any pinging whilst switching.

Answer 4

There are two ways to measure octane...research octane, an idealized measure under lab condtions, and motor octane, observed octane in an actual engine. In the US, petroleum companies are required to take both measurements and report the average of the two (M+R)/2. In other parts of the world, they report research octane. Same fuel in either case.

Answer 5

that just goes to show you what kind of screwing we are getting on a day to day basis
