[W126 Coupe] Re: Fuel Requirements or How Can I Adjust 1989 560SECTo Use 87 Octane

[XKEOTS at aol.com]

In N.Y. there is a 35-50 cents a gallon difference between 87 & 92 octane 
gas. At 50 cents a gallon a tank or more a week can be in the neighborhood 
$700.00 a year or more.
I am only getting about 12 miles to the gallon doing daily driving.
What is the average MPG on your SEC's ?

Thanks
