Just spent last week at Hot August Nights . Cruised around Reno in 97 Deg. heat, engine never went above 200. Before using WW engine would have run 210 to 215. Made a big difference. I use on a 6 gal. system 1.5 bottle of Red line and .5 gal long live
antifreeze. Read the info the Redline has on their web site. It explains a WW real well. Give it a shoot , it's not that expensive to give it a test.
