I use Quantum 0W20 longlife or shell 0W20 longline if not available, I would recommend that you use genuine or OEM equivalent filters i.e MANN Filters, dont fit cheap parts as they'llcause you more problems. I've had my 2015 C7 with 133000 on the clock for 3 years now with no problems other than a front wheelbearing and covered 30000 miles trouble free motoring, I would also advise a fuel additive something like archoil which you add ml to lots filled, and it's a fuel booster/cleaner too. Oh and dont drive it like Miss Daisy 👍
