However, the guys that are doing uoa's are showing much lower wear numbers when the tick is gone. So it is like this, what do you have to loose if one oil kills your ticks and another doesn't? Well let's just buy the oil that makes my truck tick? It just makes no sense, and I certainly do not think people should just say Redline is the only oil that can do this. I think more people should test it, find out why redline is stopping the ticks, it is the esters, pao, high moly? If we can isolate what is killing the ticks, hopefully there will be more options then just redline, or possibly motul/millers.
