i just passed 85000 on a 2006 i did the dump and fill 2x so its probably OK better than nothing anyway did wires plugs and who knows how many oil changes ( change it every month) my driving is up to 215 a day x 5 =1075 x4= 4300 a month and that is just for work, so the miles just keep adding new tires later this week--that freaking timing belt things is such a pain on a chevy pick up its about $100
