Finally, motorists in Birmingham and Sheffield have been confronted by a BBC reporter who secretly filmed them buying red diesel to use in their own cars.
It's illegal for regular drivers to use the fuel, which is about 50p cheaper than a litre of normal diesel.
HM Revenue and Customs estimates that the crime costs the UK £100m a year in lost tax revenue.
Red diesel is intended for use by farmers and construction workers in tractors and diggers.

There have been no changes to Guernsey's 2019 budget yet, despite it facing more than 40 amendments.
It was a day dominated by petrol and diesel.
Two of Deputy Jennifer Merrett's amendments were thrown out regarding withdrawal rates then Deputy Gavin St Pier found himself apologising after his committee had failed to discharge its duty on finding alternative ways of taxing motorists - proposals that will now have to be found by September 2019.
The biggest news on the opening day of debate was fuel duty, which is going up despite two amendments being placed to prevent a price hike.
That means the tax on fuel will remain at its new level of 70.1p per litre.
Motor giant BMW has recalled more of its diesel-power cars on fears of a leaky exhaust cooler.
It has recalled 1.6 million in total - included 480,000 recalled in August - and some 268,000 UK vehicles are affected.
There are 12 models hit by by the fault, which BMW says can result in fire in “extremely rare cases”.
The recall only applies to diesel-engined cars, and affects examples of the 3 Series, 4 Series, 5 Series, 6 Series, X3, X4, X5 and X6 with four-cylinder units produced between December 2014 and August 2016.
The same cars produced between July 2012 and June 2015 and fitted with a six-cylinder diesel engines are also affected.
In a statement, BMW said: “The technical campaigns initially decided for European and Asian countries in mid-August 2018 involved around 480,000 BMW diesel vehicles. During further examination of engines with a similar technical setup, the BMW Group analysed individual cases that were not included in the original technical campaigns.
“These individual cases posed no significant risk to our customers. Nonetheless, the BMW Group decided to further reduce even this minor risk by expanding the country-specific technical campaigns."
