北美用(RON + MON)/2

Husky/Mohawk o既油有10% 係酒精
會燒得快D

ethanol blend 個RON 數值會高D MON數值 會低左
雖然用 (RON + MON)/2 Husky/Mohawk o既油 係 90 octane起
但 enigne需求o既係 MON


即係如果你架車要ｏ既係87octance 你入Husky/Mohawk 都ok
因為Vancouver 各大油站　ｏ既貨源都係一樣
87octance 係最少additives 但如果你架車係要９１～９２　octance
佢d　92~94 octance 係咪”足料”就真係唔清楚

有幾個仲係91~92

部車真係會好力d
不過冇一個入89,91,92 o既入 Husky/Mohawk

Research Octane Number (RON)

The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane.

The only engine used to get these figures is a Waukesha engine used on a global scale

[edit] Motor Octane Number (MON)

There is another type of octane rating, called Motor Octane Number (MON), or the aviation lean octane rating, which is a better measure of how the fuel behaves when under load as it is done at 900rpm instead of the 600 rpm of the RON[2][3]. MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, a 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. Normally, fuel specifications require both a minimum RON and a minimum MON.[citation needed]
