premium vs. regular 850

Hey all, I have a '94 855T with 125,000 miles. Since I bought it in 1998 I have put regular unleaded (about 87 octane) and never used premium. If I were wanting to achieve max. performance, would it help to put premium in now? After 70,000 miles running on regular... or would it be not noticable enough for the money? Help please... Thanks guys, ~Cody
