I wasn't talking about diesel engines. Why would I when the thread
isn't about them? 'IC' refers to internal combustion which covers
petrol and diesel types as well as those running on alternative fuels
like LPG and so on.

The tread is about synthetic diesel engine fuel.

It's either diesel or it isn't. Or perhaps you consider alcohol or
hydrogen that a petrol engine can run on just synthetic petrol?

A compression ignition engine can also run on a variety of fuels, other
than diesel. And if you think all fuels produce the same by products when
burned, you're even more stupid than I first thought.

All the fuels are hydrocarbons and produce similar (nasty) emissions.
