Claims a 2-5 degrees drop in a 50/50 mixture. Just drove from San Francisco to Salt Lake City Utah. In a gen3 installed scangage ll previous noted coolant temp on hard pull in 98 -100 degrees outside temp engine coolant temp 210-215 after the additive temp 207-212 . Look like this stuff does work!
@Topp Cat @edthefox5 swears by their products. He hangs out in the Gen II Section. Check out some of his posts on the Redline products.
Love it. I put a bottle in the Inverter and with IR Thermometer it ruins a few degree's cooler. Same color to. I'm running Redline D6 trans fluid (95K miles and super quiet) and Redline motor oil 10-30.The motor oil is sick. You would not believe how quiet it makes the motor.
