So for some reason I've tried to search for three different things today and the search function keeps coming up with no results?
Anyway, earlier I did a quick search about API ratings to see what exactly SM was vs older oils, and it said "summer 2009" you will see GF-5 oil, and will be factory fill on 2010 vehicles.
What is the GF-5 oil, and what does it mean to cars we have now? will we see higher quality oils? or more EPA/Economy oils?
