Anyone else use the low grade stuff? Figure I saved about $2500 in gas cost so far.

You might have saved in cost of your fillups, but the drop in efficiency would offset the savings.
Given that you posted about a cost difference of $0.60-0.80 per gallon between regular and premium, your situation is the exception and not the norm. I did some quick math:
94000 miles, $2500 gas cost savings.
At price difference of $0.60 per gallon as you mentioned, you've consumed around 4166 gallons for an average MPG of around 22.56.
Not sure what type of driving you're doing, but if it's mostly highway then that mileage really sucks.
All the gas stations in my area that have high turnover all have a spread of about $0.10 between each of the grades (87/89/91).
I'm waiting for the day when car manufacturers run out of ways to make the cars more efficient with existing fuel supplies, and start forcing the fuel industry to provide the public with 95+ octane or higher gasoline on a consistent basis. Economies of scale will reduce the cost, and we can all benefit from more power + better fuel economy.
