Migration from MJ to RF left a number of inconsistencies in the code, where numbers are sometimes expressed in MJ sometimes in RF. As MJ is now legacy, everything should be labelled in RF. For reference, 1 MJ = 10 RF. Some instances have been fixed, opening this issue to track next fixes.

Yes, I tried to touch engines, but things kept breaking when I was doing so.

@asiekierka if you can run any of the checks you did... I think I put everything in order but as there's no way to differentiate RF types form MJ types, you can't be too sure...

Seems like engines were the only ones left needing this update. Closing.
