There were many types of oils available to run these engines on, and
'residual' oil is one of them.

It's a description of an oil that was a by-product of the main oil
refining process, I'll have a look tonight when I get back home and
see what the old books tell me.

Residual oil can also be used to describe other types of oil, which
makes it a bit confusing, I think that 'Shale' oils come into this
category.

These engines were built in the days when diesel oil/fuel was not
generally available, if at all, and petrol costs for big engines was a
lot of money, as were gas producer plants.
