ptjones Posted January 2, 2013 Author Report Share Posted January 2, 2013 You lose approx. 2mpg for each 10deg drop in temp. So at that temp you have lose 12mpg. Paul Quote Link to comment Share on other sites More sharing options...
ptjones Posted January 2, 2013 Author Report Share Posted January 2, 2013 I just completed 43.6mi trip with temps 39-45deg.F very hilly, 55mph, slight tall wind averaged 53.6mpg used .8gal, 28mi EV,3.9mi regen and brake s 99%. BTW I did have grill covers on with WT 195-205deg.F. At 70deg it would have been 60mpg. Pretty Cool don't you think! Fits2at 1 Quote Link to comment Share on other sites More sharing options...
Fits2at Posted January 4, 2013 Report Share Posted January 4, 2013 Paul, let me chat with my husband this evening. Does the set include the one for summer driving with the cut out? Quote Link to comment Share on other sites More sharing options...

littlebitfarm Posted January 4, 2013 Report Share Posted January 4, 2013 What diameter pipe insulation did you use? and how did it fit? If you had to buy again, do you think a slightly larger or smaller diameter would work better? Any pictures?I used 3/4" insulation. I did it differently from others I guess. I rolled the insulation up tight and just wedged it into the grill. Quote Link to comment Share on other sites More sharing options...
C-MaxJaxon Posted January 4, 2013 Report Share Posted January 4, 2013 I was thinking about shoving in some blocks of square weatherstrip like this, but smaller. I haven't seen anything that's around 1.5" that would be needed. It could be flush and nearly invisible. And maybe you could leave some of them in even in the summer. http://www.lowes.com/pd_96327-1410-AC43_4294774692__?productId=3062423&Ns=p_product_avg_rating|1 Quote Link to comment Share on other sites More sharing options...
Fits2at Posted January 4, 2013 Report Share Posted January 4, 2013 Thanks Paul. I don't have a front license plate, don't know if that matters to you or not. I'll be in touch. Quote Link to comment Share on other sites More sharing options...

The Heavy Duty Packing Tape was a much cheaper and better aero solution if you want test out the idea. If you really want to solve the problem just order a Grill Cover Set and be done with it. And it will releive some of your MPG depression. I will start shipping Sets out the first of next week. Quote Link to comment Share on other sites More sharing options...
