A hotter thermostat seems to have helped on my diesel Golf. I had struggled to consistently get 55mph on the highway and now I regularly see 60 mpg average at 60 mph. The Stant Superstat keeps 207 F when the stock thermostat held 195 F. You don't have to worry about preignition in a diesel. Ignition timing is controlled at the injectors.
