Gasoline credit cardz

[xvxax]

So, I own a landscaping business and I spent $600 in gas last month. It's about time to invest in a gasoline credit card since that's an absolutely ridiculous amount of money.. So tell me what you have, what percentage back you get, if you'd recommend it. So far I've found a chase card that gives 3% back. I mean, is there any disadvantage to getting one? I've had the same old credit card for two years now and I receive no benefits. I will pay off the card in full every month.
