Ok guys on a average ,, if the oil is changed 2 times a year winter and summer and used within the limits it was designed for..all other regular maitanance such as air filters ,plugs, etc done in the proper intervals,, how many hours can a person expect them to last ? 2,000,, 3,000 or more ? Before they need to be replaced or overhauled ? Just curious,,, Thanks in advance for your replys....
