I have used nothing but TA for the last 30 years. It came highly recommended to me from my uncle who has a fleet of construction vehicles. I can't believe how clean the inside of motors look after using this. No sludge. I keep cars a long time and have never worn out a motor, even in the old days when you were considered lucky to get 125K before motors started needing serious attention. I will post my next UOA in about 3 months or so. It tends to flow well in extreme cold. 5-30 allowed my 85 Cutlass 307 to start easily unassisted while visiting Minnesota at -29 ambient. Of couse a good battery helped.
