No, I never claimed that.

Yes, this may be the case, however the TBR has to get closer to 4,000
hours than to 2,400. Most auto and truck diesels will last at least
twice as long as similar size gas engines, so with Lycs and Contis
lasting 2,000 hours fairly routinely, the Thielert needs to at least
double that ... unless the replacement cost is equivalent to an
overhaul of a Lyc or Conti.

Of curse I did completely misunderstand you. No, please don't explain.
It gets boring.
