An Oil Change Won't Fix GM's V8 Issues, New Lawsuit Says | Carscoops
Ten owners are suing GM, calling its recall plan for V8-powered trucks and SUVs inadequate
That's interesting, I have actually been using Mobil 1's FS formula since this recall came out. My engine pre-dates the affected engines too, I just figured if clearances were never the issue with the affected motors, then mine can safely take 0W-40 too. I actually liked that the FS formula had more zinc in it than the Supercar oil, and is much cheaper. The extra phosphorous could be bad for the catalytic converters, but no issues so far lol.
