It's more of an efficiency thing, which combines money-hugging and tree-hugging.

On Planet Putzer having an old car in great shape is a status symbol, a sign of diligence and intelligence. The converse is also true. I average about ten years and 115k miles out of cars.

I guess the money-hugging and tree-hugging carry over into my gasoline powered implements of destruction. I kept my first lawnmower 18 years and 150 hours, and only got rid of it because I couldn't get parts anymore and I needed a mower that mulched and/or bagged.

My current gasoline powered implements of destruction are:

Honda string trimmer, bought in 2000
Stihl edger, bought in 2011
Honda lawnmower, bought in 2013
Stihl leaf blower bought in 2013
Stihl hedge clipper, bought in 2016

With the exception of the Honda lawnmower, everything is "professional grade." Most consumer-grade stuff is crap. My Honda lawnmower has about 120 hours on it and doesn't burn oil. My consumer-grade B&S lawnmower was smoking by then even using synthetic oil in it.

Honda consumer-grade lawnmowers (~$500) are so good that a lot of landscapers buy them instead of the Honda professional-grade ones (~$1000).

The tricks to making gasoline powered implements of destruction last are to buy professional-grade stuff, and use synthetic oil and fresh non-ethanol gasoline.

We're on our second set of Seed Queen commercial-grade washing machines and clothes dryers. The first set lasted about 25 years, limited by the lack of spare parts.
