I have a strange compulsion to change oil. On my 2012 Tundra and my 2008 Tacoma, I changed the factory fill out for Mobil 1 Syn at 1000-1500 miles just cuzzzz... I am considering changing the oil out in my 2012 4 runner (currently at 1400 or so miles) with a fresh fill of Mobil 1. The 10K oil change intervals are for synthetic oil only, but does the factory fill come with synthetic oil? I am sorry if this horse has been beat in the past. I searched around but could not find much. A little help for a oil change addict? Please?
