I was skimming through a few SUV's the other day, and I got interested in the new Acura MDX. I'm planning on getting one, but a friend told me that I HAD to use Premium Fuel on it. He said that the SUV won't run on Regular Fuel. I mean, due to rising gas prices, I'm still thinking between wheather I should be using Regular or Premium on it. If it runs on Regular, I'll use Regular, but if Premium is mandatory, I guess I'll use Premium. Is it true that I HAVE to use Premium fuel on the SUV? And does this rule apply to most or all new SUV's? Thanks!
