Re: Octane rating for fuel... (Rich2002)
Anyone know what the highest octane level is that a C5 can take advantage of? :cheers:
Octane rating is simply a rating of a fuels ability to not ignite under heat and/or pressure.
Too much octane can even act like timing retard, since the flame will burn slower once ignited.
With that said, the best octane rating for a stock C5 is what the factory recommends.
