Tom, here's another good question for you, or for anyone else that can address it: The DeLorean was manufactured to be sold in the United States with the exception of the 100 or so cars in the 17000 VIN series which were for Canada, right? The car was not technically for sale in Europe. That being the case then why would American cars intended and destined for sale in the U.S. market come with Owner's Handbooks that reference the European 91 octane rather than the U.S. 91 octane? If the 91 octane referenced in the DeLorean Owner's Handbook was the European 91, and not the U.S. 91, wouldn't your average US buyer read "91 octane unleaded only" and naturally assume it's telling them to use the 91 in every pump at every U.S. gas station they would most likely ever encounter, causing them to always inadvertently put too high of an octane in their cars and, according to you, eventually lead to the problems you described? How would your average U.S. DeLorean buyer back in '81 firstly know there is a difference between U.S. 91 & European 91, and secondly, if they did know that, how would they know that the Owner's Handbook was referring to the European 91 so that they would know they should actually use U.S. 87? That does not make any sense whatsoever. DMC did some stupid stuff, but referencing the wrong standard in an American car's handbook that would cause owners in the primary market to unknowingly use the wrong octane, eventually causing deposit buildup that would result in emission problems seems too absurd to be true. I think the Owner's Handbook is referring to, and therefore recommending U.S. 91 to be used in the DeLorean because I don't believe using slightly higher octane than needed based on the engine's compression ratio will hurt anything, unlike using lower octane in a high compression engine will damage it. Hey, I'm a noob, so if I'm wrong, educate me with bulletproof sources. Dan W.
