What happens to coolant-contaminated mixed fuel after collection?
In brief
The glycol and water layer is separated and treated; the fuel is recovered. Petrol and diesel cannot simply be separated by settling, so mixed fuel is tested, dewatered and recovered by reprocessing: blended into industrial fuels or sent as refinery feedstock, where distillation separates it again.

What coolant in mixed fuel does to value
Coolant adds volume without value, so the terms reflect the fuel content.
