I'm going to go with Amsoil Signature 0w-30 for my car, a 2014 Lincoln MKS. For the sake of simplicity, I would like to run the same oil in my wife's car as well. Her's is a 2015 Camry with the 3.5 liter V6 (2GR-FE). My question is whether it is ok to run 0w-30 in her car, if the factory calls for 0w-20. We live in Orlando, Florida, so it gets fairly warm in the summer and winters are pretty mild. Is this an ok change to make, or am I going to have to stock 2 separate oils in my garage?
