Maintenance will gain in importance. "As we have to comply with more and more stringent emissions requirements, there are some side issues that become very important," says Sauerteig. "Heat rejection, maintenance of the engine and fuel filtration become very critical. For older engines, people were using whatever fuel they could get, and fuel filtration was never a big issue. Nowadays, fuel filtration is very critical. We have fuel filters with 3-micron filtration capability. The presence of water in the fuel and the quality of the oil to be used are critical."
