I have a '11 JSW 6MT.
Have owned since april. I have put a bit over 30K miles on it. A lot of work driving.
I have gotten between 42-46 mpg (measured by odometer/pump readings).
I have found that warm weather does yield better mpg. I am sure part of this is the decreased air drag of warm air, I suspect that another factor might be that during engine on coasting when the engine is in fuel cutoff, I suspect it cools the head fairly quickly. The result is that you have an engine running at less than optimum temps for a bit.
I also wonder what the effect is to the cat/dpf. What does a minute of relatively cold air going through them do, as you would have on a long downhill while in gear under fuel cutoff?
I have been thinking more and more lately that maybe EOCing might be a good thing, especially in cold weather.
I have a lot of experience EOCing gassers, but have been hesitant to do it because cycling the ignition on off causes a lot of glow plug use and it is also a PITA sometimes to get my bluetooth to sync back up.
The solution to these issues would be adding some sort of fuel cutoff.
Has anyone done this with a newer tdi?
There is another thing this might help.
I experienced the infamous intercooler icing problem last week when it got down into the high teens/low twenties. I have installed a lower grill block using pipe insulation. I am thinking that a good bit of this icing might be occuring during fuel cutoff. Doing more EOCing could address this.
Would love to hear from anyone who has done this mod to a 2010 or newer tdi.
