Re: [DML] Re: Failed emmissions AGAIN

Hello Dan

That is a very good question. And the answer to that would be that whoever 
wrote the Owner's Handbook must have made a mistake or just forgot to 
mention that in YOUR book. I say "your" book because mine clearly states 
that in the USA 87 should be used and that 91 was for Europe. Maybe I have a 
later version of the book that was updated.
Anyway, in the Owner's Book that I have there is a mention of that on page 
40. Right on top, on the right side of the page. Here's an EXACT copy of 

Fuel Requirements
Your De Lorean is designed to operate at factory specifications at UNLEADED 
GASOLINE only of at least 87 anti-knock index (R+M/2) (91 research octane 

Is this a bulletproof enough source? :)

Of course you might say that "at least" means that it can operate on 93. And 
you will be right. It CANNOT use anything less that 87 because it will cause 
damage. Anything more that 87 CAN be used. 93 CAN be used without causing 
immediate damage to the engine but it is a great waste of money and if the 
engine is designed to operate on 87 then 93 is not as good for it. The 
higher the octane number the less chance for detonation but at the same time 
combustion temperatures are higher.
Use 87! Your car will be much better with it in the long run.
And the most important thing - 93 IS NOT BETTER than 87. It is just 
DIFFERENT! The names "premium" or "super" are just clever marketing by the 
oil companies to make the customers feel that they are getting something 
better that is worth the higher price. In reality they are just the same but 
meant for different engines. The car I have here in Europe runs on 95 (RON) 
about 91 (R+M/2). It was designed for that gas. DeLorean was designed for 91 
(RON) which is 87 (R+M/2)

I hope this clears things up for you a bit. And don't forget to check page 
40 in the Manual.
