Do bigger engines last longer?

Larger engines will generate more torque. That allows the use of a transmission that lets the engine run slower for the same given car speed. So while a four-cylinder engine might turn at 2,500 rpm at 65 mph, an eight-cylinder engine might turn at 1,800. That could contribute to longer life.

How long does an engine last?

I have seen engines last less than 40,000 miles and others that lasted more than 300,000 miles. When it comes to the time an engine will last you, look at mileage per year or how the vehicle is stored if there is very low mileage on the engine. Think of a 1916 car engine that is driven only 100 miles a year and put in storage after each use.

Generally speaking, it is easier to make more power with more cylinders. If one has two engines of similar displacement, the engine with more cylinders will generally produce more power. For proof of this, look to the AMA Supersport rulebook, for example.

What are the advantages of a diesel engine?

Diesel engines have much larger crankshafts, camshafts, and cylinders, as well as larger bearing sizes. This means that there is more room within the engine for more oil to move freely. The larger oil and coolant capacity of a diesel engine means there is better lubrication and less wear.
