Renault combustion-powered vehicles running on LPG
Renault and LPG
Petrol and LPG (Liquified Petroleum Gas) bi-fuel is a solution that is practical, economical and more environmentally friendly than conventional petrol vehicles.
Vehicles equipped with bi-fuel are now available as Eco-G technology created by Renault.
3 facts about Eco-G technology
purchase
You save money with half price or entirely free vehicle registration costs*, lower surcharge penalty**.
everyday use
Even more savings, with around half the price per litre than that of petrol vehicles. Less fine particle emissions, making it more environmentally friendly.
on the road
With 2 tanks, your driving range increases to 1,300 km***. In addition, with a Crit’Air 1 sticker, you can drive wherever you want.
*varies by region. Issuance costs remain payable.

how petrol-LPG bi-fuel works
automatic and manual operation of LPG tanks
Eco-G vehicles have 2 tanks (petrol and LPG), which are used alternately; although this switch is done automatically, you can also manage it manually.
automatic
In this mode, the vehicle will systematically use the petrol tank to start and then alternate between the two tanks by itself. Preference is always given to the fullest tank.
manual
For this mode, you decide which tank to use and when you want to switch to the other. Your decision is saved as the default setting, until you change it.
LPG engine components
LPG tank
Located in the spare wheel compartment for all Renault Eco-G vehicles.
pressure safety valve
Guarantees the vehicle’s safety should excess pressure occur.
LPG switch/gauge
Shows fill levels and lets you alternate manually between the LPG and petrol tanks.
LPG fuel line
Connects the engine to its fuel supply from the LPG tank.
pressure regulator
Regulates gas pressure to convert it from liquid to gas.
your questions about how LPG works
What are the driving benefits of an LPG engine?
With the many advances made, petrol/LPG bi-fuel driving has become more flexible and there is no drop in engine performance.
It can even be said that the LPG powertrain now offers more torque than its petrol equivalent.
Where can you fill up with LPG?
(to be localised by country) In France, LPG can be found in a quarter of service stations on average (over 1,500 service stations). You can find them on Essence&Co or MyGPL.eu to better plan your trip.
If you can't find an LPG station nearby, don't worry: you can run on petrol only, as with a conventional combustion-powered vehicle. Note, however, that your petrol tank will systematically be used on start-up, so it cannot be empty!
How do you fill up with LPG?
In the same way as a so-called “conventional” tank: - Open the fuel cap (like with a petrol tank). - Place the LPG pump nozzle in the fill hole. - Remove the nozzle when the tank is full and replace the fuel cap.
What’s more, it’s reassuring that, in France, a quarter of service stations offer LPG. If you can't find an LPG station nearby, don't worry: you can run on petrol only, as with a conventional combustion-powered vehicle. Note that your fuel tank will always be used on start-up, so it must never be empty!
Is it more complex to maintain an LPG vehicle?
Maintaining an Eco-G vehicle is no more complicated than with a conventional vehicle: maintenance intervals and costs are the same.
As with any “specific” vehicle, maintenance should be entrusted to professionals trained in the maintenance and repair of bi-fuel vehicles. As an indication, an Eco-G vehicle must be serviced every 20,000 to 30,000 km, like with a conventional petrol vehicle. Stick to the frequency indicated in your log book to make sure your vehicle runs correctly.
Although Renault Eco-G vehicles have an additional LPG-dedicated tank, their interior space remains unchanged and their price is similar to a conventional petrol vehicle. So you don’t have to change your habits.
the advantages of an LPG vehicle
With two tanks, the driving range of an Eco-G vehicle is more optimised than that of a petrol vehicle. You don’t have to fill up as often and it costs less, as LPG is 50% cheaper* than petrol and diesel. From an ecological point of view, an Eco-G vehicle emits up to 11% less CO2 and 10 times less NOx** than a diesel vehicle.
Although LPG Eco-G vehicles have two bi-fuel tanks, they don’t cost more to buy. They are also more economical to use, as LPG is less expensive per litre. They are also more environmentally friendly and have a longer driving range.
