Go with 87. It's cheaper, higher octanes don't offer any performance boosts, and I'll even go one further and say that the owner's manual clearly states to use 87 (US method; Eurospec was 91 I think). The DeLorean's PRV engines are *not* high-compression ratio, nor are we turbocharged (usually). Higher octane (as far as I know) will prevent pinging (pre-detonation), and *only* that, and usually does not offer any boosts in performance. Just drains the wallet that much more that could be spent elsewhere. :-) Hope this helps! :-) [Non-text portions of this message have been removed] To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
