Just p1ss in your tank. Comes to something when we're all happy to start touching urea just to run oil.
The ambulance has a LEZ compliant exhaust on it and i have to add stuff to the fuel at fill ups to help protect and regenerate the huge cat/dpf it has while keeping the filth down, stuff is £80 a litre. The true cost of destroying the planet i suppose. If you'r running tractor fuel then you have to clean it up. For the kids man, for the kids.
