What he said. If you actually get out and RIDE your bikes, the brand of gas becomes much less important than "oh fuck, I'm on reserve, and I don't know where the fuck the next station is. Hope its up in Bumblefuck, cause I'll never make it to Nowhereville". And when you arrive in Bumblefuck, you're happy to see the Fas Gas with the rusty tanks, and the 1960s pumps.I put 87 octane from the gas station nearest me when I'm running low.
The value of a QuickPass key fob on a bike is highly under-rated , takes me longer to get my card out and beep-boop the machine ,than it does to actually fill up ........Shell, but only because I get the most airmiles there and I have one of those quick pay things on my key for fast stops. I think the only other company that offers that option is Esso (and I like their quick pass better)
