How many engines do we really have wearing out? It's other things that bite us in the behind, like massively worn suspension components or a very expensive transmission that gives up the ghost, not to mention rust or collision damage.


Ah Garak, that is what most Cardassians suggest. But if you can by some small adjustment increase the life of the stations motor, should we not at least try? ;-b

No, not necessarily. Several of these additives can get pretty darned expensive. Heck, so can excessive oil changes.

I did some numbers about the taxis back in the day. Even going to OEM OCIs versus the extended ones we did would have used up the dollars of a complete rebuild. So, spending the amount of money equivalent to a rebuild to possibly, and only possibly, extend the life of an engine marginally is not a good return. Of course, we've never seen evidence that any of these additives (or synthetic when a conventional will do) will actually extend the life of an engine.
