In your '95 (or any "garden variety" Contique , for lack of better term) , you'll do just fine using 89 octane fuel (probably even 87) . You shouldn't see any ill-effects at all . 91 octane won't hurt anything either , except your wallet  . The SVT line , however , is said to need 91+ octane due to higher compression & whatnot . Some have used less octane in their SVTs and said they noticed no difference . I won't use anything less than 91 in my SVT , though .
