[W126 Coupe] Fuel Requirements or How Can I Adjust 1989 560 SEC To Use 87 Octane

[XKEOTS at aol.com]

Hi All,

I am sure, any of us here in the USA, are not happy with the current fuel 
prices. Also the fact that we have to use Super in our 560 SEC's.
I recently picked up a 1980 450 SL as it uses 87 octane and the mileage is 
better than the 560. (I have no intention to sell my 560 SEC. It is the best car 
that I have ever owned and I have owned over 100 cars)
Is there any way to make our 560's run or 87 octane?
I couldn't believe yesterday when I put in 12 gallons of fuel and it cost me 
$42.00.
I was always under the impression that fuel injected cars need a lower octane 
than carbs.
Any help or thoughts on this would be greatly appreciated.

Thanks
Jack Miller
