Like anything else....go to any forum whether it be a modern firearms forum, ML forum, Flintlock forum, diesel forum, chevy forum, etc., you are always going to find biased opinions. The best you can do is buy and decide for yourself. If it's not to your liking, you may be able to improve it to your liking. Example: I was looking for the best oil for my powerstroke 7.3L! Every forum I went to, 20 different oils were the best, and the same 20 oils were the worst! Then I asked about AMSOIL....big mistake!! Replies: amsoil too expensive, amsoil no good, this is better, that is better. Sooooo.....decided to watch some youtube videos of different oil comparisons for flows and lubricity in sub-zero to extreme heat temps. I put amsoil in all my vehicle engines, tranny's and differentials!! My point is....IT'S A CRAP SHOOT!!
