93 Allante, 06 CTS
Discussion Starter · #1 ·
I have a 93 Allante and have had a few Cadi's in the family over the years, my question is, do the new 4.6L N*s require premium fuel? Luckily my Allante doesn't get driven all that much but it sure hurts to pay a $0.30 premium on fuel at the pumps. BTW, am considering new STS or SRX so just curious.
