The Delorean will run just fine on regular-87 octane. You can't hurt it in any way by using higher octane. The one effect I can notice on higher octane (on any car) is slightly better gas mileage. Not enough to warrant the higher price, especially at today's prices. All brands of gas are far superior to gas mixes of even just a few years ago. They are ALL blended now for fuel injection. This is of course assuming your engine is still set up stock with the factory recomended settings for timing, spark gap, mixture, etc. Do not add any additives like fuel stabilizer, octane booster, lead substitutes, etc. It is not even a good idea to use gas line anti-freeze (aka dry gas) anymore. Injector cleaner is probably the only thing you can use and then only on a very infrequent basis. Techron is the cleaner of choice. It should not be necessary to use it on a car that is used regularly. Today's fuels include an injector cleaner already.
