Since I put on my grill block at the same time as I put in my SGII, I really can't say how much warmer my car is running or how much mpg was gained by the grill block alone. However, it does have a 180f thermostat and now routinely runs between 192-202 with routine excursions to 213f when climbing long, continuous grades. At the same time, I'm getting 25-30% better mpg this winter over last winter, using the same snow tires and same winter gas. I was up over 40% until winter got nasty over the last three weeks. While I believe the overwhelming majority of that gain has come from improved hypermiling technique, I have to believe that at least some is coming from the higher operating temperature, too.
I know, there's no science in any of that, but until warmer weather returns so I'm challenged with overheating issues, I'm not going to do any A-B-A testing.
