Why do modern engines last longer?
They have a larger crankshaft and camshaft, which requires larger bearings and sturdier main and rod bolts. Larger crankshafts and camshafts also mean increased clearance which allows for better oil flow. Better engine lubrication equals less engine wear on the engine which helps improve the longevity of the engine.
Why do older cars last longer?
Old engines made a vehicle operate, but they weren’t very efficient. … A cleaner combustion process means a better engine that lasts longer, and saves on fuel and oil in the process. Motor oil from just a few decades ago was simple at best.

Are older cars worth it?
If reliability is your top priority, you probably don’t want to buy a vehicle that’s too old. After all, the older a car is, the less reliable it’s likely to be, even if it’s a well-maintained, low-mileage vehicle, such as a Toyota or a Honda. Reliability does depend on the vehicle and how many miles it’s covered.
