Manuf. (Dura Lube)
For getting temps down- No
For stopping thermistat from intermittent sticking open- Great after 500+kms!
My thermistat which was stcicking every 50 -100kms does not stick anymore. (500kms)
Draw your own conclusions , but I had this problem for the last couple months and now it has dissappeared after 10-20kms of use and going strong!
