How Much Does Red Diesel Cost Per Litre?
Why You Can’t Just Look It Up
It’s one of the most common questions we hear — and it’s completely understandable. With fuel prices impacting your bottom line, it’s only natural to want a quick, clear answer.
But here’s the catch: red diesel prices can’t simply be listed on a website like supermarket fuel. That’s not because we don’t want to share them — it’s because they change all the time.
What Is Red Diesel?
Red diesel is a rebated fuel used for specific off-road and non-commercial applications. It’s chemically very similar to standard white diesel but is dyed red to mark that it benefits from a lower fuel duty rate. That same red dye also helps authorities spot illegal use.
You may also hear it referred to as gas oil, and it’s subject to strict regulations about who can and can’t use it.
Why Red Diesel Prices Fluctuate Daily
The price of red diesel (also known as gas oil) is tied to the global oil market, meaning it can vary day-to-day — even hour-to-hour — based on:
-
Crude oil prices
-
Exchange rates
-
Refining and supply costs
-
Distribution and delivery location
-
The quantity you order

How Long Can You Store Red Diesel?
Red diesel has a shelf life of around 12 months when stored properly in a cool, dry tank. Over time, it can degrade and attract moisture, leading to microbial growth and filter blockages.
To keep your fuel in good condition:
-
Use high-quality fuel additives
-
Store in a suitable tank with good ventilation and minimal condensation
-
Consider using a tank telemetry system to monitor fuel levels and avoid contamination
