sfphilly838 Posted January 10, 2006 Share Posted January 10, 2006 I wanted to see if folks had an opinion on using premium unleaded versus regular unleaded on their GX. I am going to pick up my 2006 GX470 in three days and I believe that the car is suppose to be filled with 91 octane..... Any thoughts or comments are welcome? Thanks in advance Link to comment Share on other sites More sharing options...
