Tuscola, IL | I think there is plenty of real world argument to how powerful and reliable the tier 4 engines are compared to even the tier 3. That’s what happens when you set an arbitrary date and not let the free market develop something better. If someone were to produce a clean burning engine that increased fuel economy and reliability over an old mechanical engine, it would take over the market. When the government says you have to meet these emisssion standards on this date, you get an engine that does that and just that. | |
