I worked the phones for a **** dodgy brothers petrol company selling this stuff.
Apparently alot of people get put off when they use it for the first time, and their exhaust starts putting out lots of black smoke (especially common in trucks).
They said it was the biodiesel "cleaning out the engine" or some crap..
They also never paid me $800 in back pay
Got sacked when no-one would buy either their crappy "in your buisness" discout vouncher books (only $1150 for a 6 month supply!, FOUR CENTS OFF!) or their pointless "Business fuel cards".
Guys running it had no clue. Changing their ideas every few weeks, little to no supervision of us, we played cards for most of the last 2 weeks. Basically phoned everyone we possibly could with the resources they gave us (a handful of old phone books), and they would not let us phone anyone outside our local area.
In the last week, when we finally got some more numbers/contacts, on the 2nd day we were greeted with a nice article in the major NSW newspaper of the company ruining a dozen cars with fuel that had water put or drained into it. Made the job super easy. Even easier than usual.
