Straight gasoline = 15 mpg, 30% diesel blend = 18 mpg

Here at present low octane gasoline is $3.25/gal and Winter diesel is $3.55/gal

$3.25/15 miles = $0.2167 / mile

(3.25x.7) + (3.55x.3) = 2.275 + 1.06= $3.335 / gal blend

$3.335/18 miles = $0.1853 / mile

A saving of $31.40 per thousand miles in fuel cost.

I am experiencing no smoking or misfire. I discount all fears of filter clogging, injector clogging or valve stem depositions. If I've misjudged the fuel system seal compatibility I'll pay a hefty penalty. If there were misfiring then I'd be concerned about the cat., but absent the misfire I expect it to have a normal life.
