I just normally sniff the tank first off. That generally tells me straight off either way. Like you said Max, if it's a modern diesel as in common rail particularly, it will be detrimental and end in tears for the owner I just dump the whole tank no matter how much petrol is suspected to have been put the tank if the engine has not been run and work a solution out if it has when there is no immediate obvious problems. Not worth the chance guessing with the potential costs involved. And I keep the diesel/petrol for my workshop as a parts cleaner, the more petrol the better. And the other way round too, again if it's a modern engine with O2 sensors I dump the fuel and keep it also. Petrol with a little diesel is the best general cleaner period and a kerosene bath with a water table and grate under it for the real heavy-duty work. All these Eco-friendly cleaners are useless With pre and post O2's and a catalytic media, the risk of poisoning these components with diesel again is not worth the risk. Another easy way to see particularly in hot weather is to look for vapors coming out the tank and or bleeder fittings. Also, petrol is freezing on the scratchers in the cold weather indicating petrol in the diesel.
Helpful tips to help those in need of knowledge. Thanks Miracle Max🙌

Good advice. Thanks for sharing your comment 👍

Thanks
If these fuels were in an old sigma it would run fine as they love oil too.
Fair comment
Fuel issues first job tomorrow
Sounds like fun! 😉
