I do the oil changes in my mother's Lib for her, and I have been dying to use GC in something. Since every motor vehicle in my immediate family is a diesel (3 trucks, 1 Jetta TDI), I don't have an opportunity to use it here at home.
Would it be a good thing to try in her Lib 3.7 for a 7500 mi run? Specs 5w-30 and I have been using the MC 5w-30 blend as of late, with decent UOA results on 7500 miles.
