So I did the switch on my GFs Camry to the Mobil 1. It really isn't THAT much more expensive that dino oil, I just buy a 5 quart bottle for $19 at walmart and I don't even use all of it. If you consider she was paying $25 an oil change at Jiffy Lube before I started doing it, its no extra money out of her pocket, just extra work for me, which means she does my laundry, which she ususally gets fed up with it being all over the floor and would have to do it anyway, so it all works out. I'll let you know if it ends up burning less in about 1500 miles
