Why choose dual fuel? 

Looking to reduce your fuel costs and emissions?

A dual fuel vehicle could be the answer

Dual fuel vehicles have a standard diesel engine that has been adapted to burn a mixture of diesel and LPG in the combustion chambers. By replacing some of the diesel fuel with LPG – or, better still, BioLPG – the vehicle will have reduced fuel costs and emissions as LPG is both cheaper and lower in carbon than diesel. By substituting LPG for just 25% of your normal diesel consumption, you could reduce CO2 emissions by 6% or 8 tonnes.

Four reasons to consider converting to dual fuel

  1. Ongoing fuel cost-savings of around 16% when switching from diesel1
  2. Reduced CO2 emissions (we’re talking between 10% and 20%)
  3. A small investment you can quickly recover
  4. Prolongs engine life - As LPG is a cleaner-burning fuel than diesel, converting to dual fuel can actually reduce wear and tear on your engine.

In fact, here at Calor we think it’s such a good idea we’ve converted a quarter of our own long-haul diesel trucks to run on dual fuel. That single decision has already reduced running costs and saved 74 tonnes of carbon emissions in the first year!

Here’s how we’ve worked out the savings:

What is dual fuel?

Dual fuel means burning a variable mixture of diesel and LPG in the combustion chambers. By simply displacing a proportion of the diesel fuel with LPG, a vehicle will reduce both its fuel costs and carbon emissions because LPG is cheaper and lower in carbon than diesel. It’s straightforward and cost-effective to upgrade existing diesel engines and enable your vehicle fleet to run more cleanly and economically.

Go green with BioLPG

Take your emissions to a whole new low with BioLPG

If you’re considering switching from diesel to LPG or dual fuel, why not go the whole hog and choose BioLPG at no extra cost? Produced from a mix of renewable feedstocks (basically plants and waste), it results in even greater CO2 savings than standard LPG.

It's good to go green with BioLPG

What’s more, being chemically identical to conventional LPG, the two fuels are interchangeable. No changes are needed to any existing LPG equipment or infrastructure, making BioLPG the ultimate drop-in fuel. Here are a few reasons why BioLPG could benefit you:

BioLPG provides carbon emissions savings of up to 80% compared to conventional LPG, making it a much more environmentally-friendly choice.2
You won't notice any difference in acceleration speed, or overall performance. In fact, you won't notice any difference at all! BioLPG is chemically identical to standard LPG, making it the ultimate drop in fuel. 
Doing the right thing doesn't cost any more than conventional LPG. There's no hidden costs either - you won't need to change any of your existing LPG infrastructure.

How to switch to dual fuel

We make switching simple

Dual fuel technology requires relatively low capital investment and can be swiftly installed using, for example, Mercury Fuels' conversion technology. This involves using a second set of LPG fuel injectors, an LPG fuel tank, pipe work and associated fuel management system. The capital payback is often achieved within 12 months and our convertor partners provide warranties for the converted engines.
