Back in '85 I had a 'fresh' '83 SD that routinely did 32mpg. The current '85 does maybe 30 mpg and the '84 with the 3.07 does around 27 mpg. Tired vehicles and fuel changes most likely...
BTW, does your SD always run that hot?

That's about where my SD sits for temps. It is routinely over 100F out right now.
I have been getting about 17-20MPG lately driving mixed city and highway. I have a new set of Monarks installed as well. I also mix in some cetane boost from Diesel Kleen.
