The truck doesn't use any oil between filter changes and has the probably never been driven without seeing full throttle. The truck will likely rust away before the engine dies....

Those import engines have to work a lot harder than your truck engine, so your comparison isn't transferable to them. The Yaris and Corolla engines make ~70 bhp/liter (106 hp/1.5 liter from the Yaris, and 125 hp/1.8 liter from the Corolla). Your truck only produces ~36 hp/liter (210 hp/5.7 liters).
