Type of fuel to use

["mccarthy410" <mccarthy410@xxxx>]

Hi,

I am a new prospective owner of a DeLorean, before I buy, I'm 
gathering all info I can. One question comes to mind, I know the 
manual and several sites say to use 91 Octane fuel, only thing close 
to it is 93, and that does get expensive. Can 87 or 89 Octane be 
used with no ill effects? I'm told how the Europeans and how the U.S. 
rates gasoline are two different things, any truth to this?

Thanks.
