East coast cars and mid western fuels
How does a corvette lS-1 engine tolerate the different fuels you need to use as you cross the country? Is the fuel in the midwest vastly different from the Sunoco supreme 93 octane I use here around Phildalphia and what is the fuel like in say California? Do East coast cars run differently on these different blends?

if your car is stock or has the stock timing/fuel table, it should be able to run on 87 octane without problems. some people say they hear knocking but I never had any issues with it.

I just finished a road trip from NC out to CO and didn't have any problems. I was kind of worried one time I had to fill up at a gas station and all they had was that new corn oil stuff but it ran just fine even on that so I dont think you'll have any problems.

Should not be a problem. I've driven up to Maine, CT, MA and all over and never had any problem other than the a$$nine cost for the crap. 
They have synthetic oil. How's about some synthetic gasoline.

If your car is stock or not tuned for 93, it will run fine on all grades. The computer will retard timing to compensate which will equate in a small drop in performance. That's what knock sensors are for. As far as stock corvettes go... theres nothing different between the models based on where it was sold.
But to answer your other question, most CA gas stations have 91 and that is likely what you would be running if you drove out here. There are a few scattered places with 93, and a probably rare couple with with higher than that.

Too bad nobody in the Midwest has Corvettes...
I'm thinkin about tradin my tractor in on one, but since all we have around here is inferior gas, maybe I should keep the john deer.
Why would you think that cars on the East coast run differently than anywhere else?

Seriously though SD has 91 all over, so does every other state, it's all in what you find where. SD for instance has it everywhere because we tend to have a few motorcycles during the summer, and that's all most of them run... (or, tha'ts why a manager of a local get'n go told me once... I think it was "Herb" induced..) A couple stations even have *gasp* 93 octane Shell fuel.. some of it is even deoxyngenated "For collector car and off road vehicles only" gas.. (WTF? Who cares, really)
Anyway, you'll be quite fine I imagine. just avoid the E85 pumps.

I took a 6000 mile trip earlier this year to California, took a different route there and back, hit most of the states from Ohio to California, and never had a problem. Like somebody else said, the highest octane I could find on the west coast was 91, but she ran just fine. I did take a couple cans of Techron with me, though!

Corn Oil? LOL I grew up in Nebraska and we never had corn oil. You must be talking about ethanol which is alcohol made from corn.

In 04' I took My 01' on a nearly 10K trip to the West coast and back.
I DID notice "pinging" under hard acceleration using the West coast 91 octane fuel.
Here in Central Ohio, I only use 93/94 octane Sunoco, and have never had "pinging" under acceleration.
I don't know what to make of this, but it did happen.

Your car should run just fine regardless of where you have to buy gas.

When ever I can get Sunoco 93 on the road I do it. A Sunoco station just opened 4 miles from my house.

I live in Ca and Co and I hate coming back to Ca because the highest Octane is 91. We have 87-89-91 here. When I am home in Co I get to choose between 85-89-93 which makes more sense to me. It kills me how often I see expensive cars putting 85 octane in their cars, man I could never do it, not even in my Honda.
