From another post I saw Savvy recommending the engine be flown as frequently as possible. This seems a very well proven common prescription for obtaining the most hours. But those are engine hours and not longevity in terms of total age.
If I can get 2000 hours TBO from my engine if I run it 5 hrs/wk (total made up number) then I get to TBO in 7.69 years and may have to do some extra flying just for the sake of flying.
If I run my engine for 1 hr/wk and only get 1000 hrs TBO I get 19 years of service. Again, totally made up numbers. Assuming I am a geezer who is no longer padding the logbook I can save money on the unburnt fuel. In this case it would be somewhere around $50,000 not including oil and other consumables.
As you cut the hrs/wk down, the longevity will increase to a point then start decreasing again owing to hangar rot. Or hanger rot depending on what you use to maintain.
Are there numbers out there that show the sweet spot for total longevity?
