The maximum theoretical efficiency of a heat engine is 1/3rd (33.3...%). 
Hence the minimum energy loss (converted to waste heat) is 2/3rds 
(66.6...%).

If you are talking about practical efficiency, then you are talking 
about what percentage of the available 1/3rd is used. IIRC, in a 
high-efficiency gas-turbine engine, that's about 90%. Or about 30% of 
the fuel energy.

Reciprocating internal combustion engines have lower efficiency, perhaps 
that's what you have in mind with your 60% loss. External combustion 
engines have even lower efficiency of course.
