New Chevy 6.0L gasser -- Octane?
Just bought the new Chevy 2500HD with 6.0L gas ... and wondering what you guys run for octane. And why you choose it? -- The 'why' is important too ... because it's not just about mpg, it's about ...

I run 87 on my 2008
I have tried 93.
My "butt dyno" or non scientific mpg formula gave me any indication or added value or mpg increase.
Might get a tad more power when pulling, but that's not enough for me to justify the $.30 more /gallon.
If it got me 2-3 mpg more, I would. But it doesn't. Unless my trip is downhill both ways.
