Premium Fuel in the 06' SI????

So im looking at getting an 06 SI and I was just reading on the honda website that it requiers Premium fuel? Okay so the compression is only 11.0:1, is honda serious about the premium fuel thingy or can I get by with running regular...especially with the gas prices recently.

Yup 91 octain according to the SI manual same ocatin as the Type S. You do not want to go lower then this.

I have a '02 Si. Do I have to use Premium fuel? or is this only in the new ones.

No you do not need to you do not have a DOHC motor in your Civic.

02 Si's are DOHC but they don't need 91 octane. Unless you're from canada then you're 02 Si is probably a coupe which is the equivilant of the American ex. But either way you're safe on regular.
