2003 Toyota 4runner, 205,000 miles. Changed oil and filter every 10,000 miles. Does not use oil or leak oil. Used it a bunch for hunting and fishing. Now 100% asphalt driven. Such a great old V8 engine.
2015 Toy Tundra 5.7 liter non-flex fuel, 90,000 miles. Changed oil and filter every 10,000 miles. Does not use or leak oil. Runs great and runs offroad often hunting.
2018 Toy 4runner, 40,000 miles. Changed oil and filter every 10,000 miles so far. Does not use or leak oil. Runs great and probably 98% hwy driven.
So for me and my Toyota collection, it'll be the factory recommended 10,000 mile interval with full synthetic.
