TBO or SMOH? What about if you've been using it from the start?

At 1000 hours they are both about the same
The advice I got was not to START using it on a mid to hightime engine,
because of existing buildups which can dislodge.
If they have been used from the start, and performed as advertised there
shouldn't be any buildups. But personally I would ask the manufacturer
first.
