General Discussion / Re: My new v9
« Last post by Kev m on Today at 11:41:35 AM »Couple of thoughts:
* Ethanol is a bogeyman. I don't like it for containing fewer HCs but it has never caused me a problem in the decades I've had to run it.
* Yes, in hot weather or really getting in it, I will occasionally get pinging on my smallblocks if I run less than 91 AKI. BUT, if being gentle or at lower temps or higher altitude, it's generally fine.
* "Premium" is a poor label since it's meaning varies. One station's or location's premium is not the same as another. And, in naturally aspirated motors octane requirements will vary with altitude.
