    6th place

How it was tested

  • lubricity and wear scar test using a lubricity tester
  • carbon buildup cleaning test on highly carbonized metal
  • dust attraction test after driving on a gravel road
  • cold temperature flow test at negative 40F for 12 hours
  • corrosion resistance test with hydrogen peroxide, vinegar, and salt, tested with and without prior heat exposure at 400F for 1 hour

So, which brand is the best? I think that really depends on what you're looking for. Unfortunately, none of the brands were perfect. However, there were quite a few brands that performed very well. Two of the brands that really stood out to me include the Clean-Oil as well as the Break Free CLP.
