After 1000 miles on the 260E, I have a total average of 20.9mpg. A low of 19.9 and a high of 22.1. (all trips about 50:50 city freeway)....I bet this thing only a long trip freeway only could get 25!
I'm gonna replace the rotor and engine temperature sensor as there is no history of the rotor being replaced and the engine temp sensor looks like it has been caked in oil and dirt for a long time and doesnt look too nice. We'll see if they make any difference. I figure if it helps even .5mpg it will pay itself back over a 6months.
This car goes about 115miles more per tank than my wagon! Thats how piss poor the mpg is on my wagon right now
