I have to side with GlueGuy. I am a preventative maintenance Guy myself. You know an ounce of prevention is worth a pound of cure etc. etc.
I never leave any normally wearing component in service until it fails. This is simple disrespect for the concept of PM and falls under LOM (Lack of Maintenance)
Our lamps (head & Tail) in our vehicles get changed ever year. Our wiper blades twice a year. Oil/filter gets changed every 3,000 kilometers. New battery every 5 years or immediately if the battery gets killed. Tires are replaced at 50% wear. We fill up when the gas tank is half full. Thermostat and fan belt every two years. Tranny and diff fluids annually.
Yes it is expensive if you do it all at once that is why we do it on an ongoing continuous basis.
Guess what our equipment never and I repeat never lets us down in a serious way due to normally wearing component failures. Haven't had a flat in more than 14 years. The wife and I put on 50,000 kilometers every year with daily 35 Kilometer commutes into the city.
The major components take care of themselves if you take care of the small stuff.
There is an additional pay back for all this effort, everyone wants to buy our vehicles when we are finished with them.
