What grade gas is best to use in 2003 DX Civic Manual Tran.?

I just bought an 03 Civic 5 speed with NO Vtec. Is it ok to use premium gas? Is there any benefit from this or can it actually be bad for it? Just curious, I want my engine to run at top performance. I have a cold air intake on the way!....can't wait for it to get here.

Thanks

Run whatever it says in your manual, which I'm sure is 87 octane. There will be no benefit to using anything higher in your car.

Wouldn't there naturally be less additives and with a non variable timing motor help prevent detonation ? if anything ?

If it doesn't call for premium don't waste your money. I really don't think a stock 03 DX is going to have any problems with detonation.
