Red Diesel

What is Red Diesel?

We supply red diesel, also known as gas oil and 35 second oil, in various quantities ranging from 20 litres to bulk quantities. Gas oil is a cost-efficient fuel, commonly used in the construction and agricultural industries. Gas oil is illegal to use on the road but is a cheaper option in comparison to road fuel due to the way it’s taxed. Online Lubricants Ltd. is a registered gas oil supplier with HMRC.
