I see some here say they've only changed oil over the hundreds of thousand of miles they've owned.
Well the 100 series is incredible. But, "All Machine" need proper maintaining. The 1 million mile 4.7L 2UZ-fe VVT was Dealership maintained at one Dealerships the most. It logged 117 service calls. That's in service, and average of every 8.5K miles at Dealership. In less than 10 years, of mostly long haul HWY miles.
What is a Toyota Tundra with more than a million miles worth? For Toyota?s production engineers and team members, the truck?s longevity offers invaluable insight for future products. For Sheppard, it was worth a new truck.

BTW: I saw article some time ago. That same Dealership, has a second hit 1MM now. Must have a good shop foreman and crew!
The PM Toyota schedule, has 2 different mileage use schedules. One is each 7.5K mile intervale the other 5k miles ( for server use (stop and go, short trips under 5 miles, car-top carrier, towing, dusty roads, snow, water, sand)). Some condition required daily service.. PM schedule also is based on months, whether driven or not.
20 years and short trips with many of starts and stops. Is so much harder on a vehicle. Age alone cause all rubber to leach out it's plasticizer. Rubber bushings, hoses & seal dry out. Seal kept wet with good fluid, will last the longest. Bottom line. If someone selling me a 20 year old w/150, 200, 300K miles. States: "I just changed oil, It never needed anything else". I know, I've my work cut out, to bring back from the brink! I also know that it is not and accurate statement.
