Jim is good people. I have been running the same 8854 oil Linc switch to, just did a drain &a fill on my tranny with 1150, and swapped two gasser work trucks to 5w-30 that Jim just did a 21 or 22k oil change on his 5.0. Haven't tried the grease, but have been wanting to since reading how much Linc likes it. I can't believe it's taken him this long to swap to 8854 in his 6.7.
