More and more proof to stay away from all the incompetent dealerships and if possible to do oil changes yourself... I do mine for over 15+ years now and use 100% Mobil 1 fully synthetic w/o any issue... just bought me today a great gift a heavy duty (weighs around 100lbs) BRAND NEW Michelin 3 1/2 Ton Industrial Quality Floor Jack by Michelin from SAM's club to make tire rotation easier for my Toyotas and I just found out that I paid over $20 less than same one sold on eBay (haaah, hoooray)... what an awesome vehicle the 2007 TCH is...
