MPG Vs. Thermostat = WTF???
what do you recon to this? My '99 2.4 JTD was running at 70 degrees on the dial, got there quick and stayed there rock solid. I thought all was well and that was normal for a JTD. At this stage it was doing 43mpg.
Then I read that it should be hitting 90 like my petrols. So I bought a new thermostat for it, fitted up and bang, 90 degrees on the button, and I expected my mpg might pick up a bit to 45ish since it wouldn't be running in cold fueling mode.
Was I wrong! Mpg had dropped to 39, same commute, same driving style, same fuel. What the heck has happened? Is it likely I've trigger something else now it's running at corect temp? Anyone got any ideas or experience?
