In the past 35 years I've always used Castrol..back then all they had was conventional GTX..Now I use the synthetic EDGE..Never had any engine problems.
I have a 2015 V6 (3.6L)...
I've done two oil changes now...I pre-fill my oil filter first before I install it.. I use the WIX/57502XP filter, because I also use Castrol Synthetic Edge oil,w/Dexos (5w30)..
Anyway..I put in a total of 6.5 qts and that brings the level right up to the top of my hash marks on the dip-Stick..This is after a few minutes of running, then I shut it off and check it within about 10 minutes of running.
Four Ball Wear (ASTM D-4172)
The Four Ball Wear Test determines the wear protection properties of a lubricant. Three metal balls are clamped together and covered with the test lubricant, while a rotating fourth ball is pressed against them in sliding contact. This contact typically produces a wear scar, which is measured and recorded. The smaller the average wear scar, the better the wear protection provided by the lubricant.
As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil produced the smallest wear scar of the tested lubricants...
Next best was Castrol
