wow this thread has turned mean! I have run regular gas in mine with no ill effects at all. the knock sensor does the same exact thing if you run 91 or 87. it's still advancing the timing until it detects knock and then backs off. if you run 94 octane you'll have even better performance than 91 but saying 87 will damage the engine is about as likely as 91 damaging the engine.
91 is all we can get in california, but on the east coast 91 is definitely not "premium" fuel.

California has 91 gas because we put a small amount of ethanol in our gas to reduce emissions.
Yes modern cars can reduce and advance timing to compensate for lower and higher octane gas. Putting lower grade gas was only meant as a tempory solution in situations where there is no higher grade gas available.
Think about it, you can survive on cup o noodles for the rest of your life, but its not really good for you and it'll probably cut your life shorter.
Higher octane gas will only help you if you have a high compression engine such as FI or NA with high compression pistons. Most of the lower end c models will not benefit from higher octane gas.

Hence the reason diesel is more expensive then premium gas in the states because our gas prices are closer to market value.
Also one of the reason why diesel is so successful in Europe and hybrids are more successful in the States.

It never ceases to amaze me, when a thread many months old is brought back up with a post that carries on like it's a response to something mentioned recently 
As for the east coast - I've seen some Sunoco stations where "premium" is 91, and "Ultra" is 93. I remember when "Ultra" was 94...

you can't really compare europe to the US, since the majority of Europe taxes the crap out of petro to force people to use diesel.

i think people think there some giant conspiracy with the automakers and big oil to make you spend more money on gas.
When its probably the opposite, the price of gas has really pressed the automakers with maybe the exception of honda, hyundai and mini. Even now with the price of gas where it is, has completely killed any momentum GM and Ford had to becoming profitable again.
