From my Prius transaxle oil studies: - < 1000 miles - early change to the left over manufacturing crap out.
- ~5,000 mi - dilutes the residual oil debris from what can's be drained out.
- follow manufacturers recommendation.
For an engine, I would divide all by a factor of 10 due to higher stress and heat.
