However, high performance engines run a much higher compression, and instances of fuel combusting itself prematurely disturb the workings of such engines in a very undesirable manner.

Is there any way to average resistors together to get a tighter overall resistance tolerance?

"Gas Station Pump Five Octane Ratings" by Original uploader was Bobak at en.wikipedia - Transferred from en.wikipedia; transfer was stated to be made by User:Matt.T.. [2], The higher the octane number, the more compression from the piston the gasoline can withstand before igniting in the engine. All other compounds and blends of compounds then were graded against these two standards and assigned octane numbers. RON, however, is the most commonly used rating worldwide, and for all practical purposes, the only one that you should know about. It's definitely unpleasant to the eye, much like $ \mathrm{C} 0{}_{2} ".$. To understand the importance and use of octane rating, we first have to understand the qualities that a fuel must possess to be suitable for gasoline-powered internal combustion engines.
