yes, trade out the salt/sand business for significant bugs in the south during the summer. I would be careful with high pressure on those aluminum fins though. They can be easily bent. I annually clean my home AC condenser coil to keep up efficiency. Texas summers are hell especially along the gulf coast.
Diesels have better thermal efficiency than gassers. What this means is the energy content in the fuel is better converted into mechanical output and less thermal energy leaving the exhaust port. It is interesting to note that as compression ratio increases, gassers thermal efficiency increases. I know diesels have a much higher CR in order to get the diesel to detonate on compression.
