Forgive me if this has already been asked, but I am new to the forum. I have a 2005 TL that I only ever used 89 octane and it has always run beautifully. I am getting a 2012 TL AWD later this week and am wondering if the 89 octane will be ok for it. I see they call for 91 octane. What do you use in yours and how does it run with it?
