True. Every type of equipment in the world has its usage measured in terms of hours except for one: cars. The reason is because cars have odometers and not hour meters. Some people put hour meters in for this reason. I have thought about putting a "pre filter" in the tube to the air filter box to keep the rif-raf out. A lot of dirt piles up in there.
