Gas Oil and diesel were always considered to be the same thing when I worked in industry.
I have just copied and pasted the following from the website of a fuel distribution company;-
Red diesel is also known as gas oil, 35 seconds, medium diesel, heating oil, tractor diesel, cherry, generator fuel, digger fuel and many more.

Red diesel is the low duty form of diesel and can be used in off road untaxed vehicles i.e. agricultural/industrial/construction machinery and as home heating only.
Using red diesel for other purposes is against the law.
Red diesel is minimally taxed and can not be used as automotive diesel fuel.
Customs and Excise regulations require minimally taxed diesel to have a special red dye. This way the inspectors can quickly and conclusively identify the presence of red diesel and take appropriate action against the offender.
