a few years back, i had a corvette with the digital oil temp gauge and when i switched from regular oil to mobil 1, the oil temp ran about 15to 18 degrees cooler. so did the water temp. i would assume less friction so less heat. couldnt tell any performance gain or loss. just run cooler. maybe some of the zetec guys should try this stuff to reduce the engine temp readings on their gauges. i would like to find out if that works so i could try it in my next hot running zetec that i have for sale. anyone who trys, post your results for the rest of us.
