Anti-crisis solutions for fuel savings

• In March 2026, unleaded petrol exceeded €2 per litre and diesel reached €2.22 per litre, an all-time high that is taking a heavy toll on drivers' budgets.
• Whether you have a diesel or petrol engine, lowering your vehicle's fuel budget is possible thanks to Shiftech with engine reprogramming or E85 conversion.
• E85 conversion by reprogramming makes your car Flex Fuel: you can run on E85, unleaded or blended fuel without any constraints.
• The combination of E85 reprogramming and Stage 1 is the ideal solution: more power, more torque, and half the cost at the pump.
• For diesel engines, Stage 1 reprogramming can save up to 10% on real consumption, often paying for itself in less than a year.
• Superethanol E85 remains stable at less than €0.81/L, or up to 60% cheaper than petrol.
• If your vehicle is not compatible with reprogramming, the EFlexFuel approved box is a plug-and-play, reversible alternative.
• Shiftech guarantees to restore your vehicle to its original configuration free of charge for 5 years, and has a network of centres throughout France and abroad.

Filling up at an ever-increasing cost

The surge in fuel prices seen in March 2026 is not an isolated incident. It is part of a particularly tense geopolitical context, with direct and immediate consequences for your wallet.

Difficulties for heavy drivers

While the rise in prices is affecting all drivers, it is hitting even harder those whose vehicles are used for work or who make long journeys.

Individuals: home-work journeys:

An employee who travels 50 km a day now pays between €150 and €200 extra for fuel each month. Low-income households with just one car are in the front line.

Taxis & VTC :

With 200 to 400 km/day, taxis and VTCs are experiencing an explosion in their operating costs. Fuel can account for up to 30% of their variable costs. Every cent per litre counts.

Corporate fleets:

For SMEs and large companies managing a fleet of vehicles, fuel has become a critical cost centre. Travelling sales staff, after-sales technicians, deliveries: every kilometre costs more.

Craftsmen and the self-employed:

Plumbers, electricians, home helps, childminders: professionals who travel on a daily basis are seeing their margins shrink with every trip to the petrol pump.

If you run on petrol, you have access to a particularly powerful solution: conversion to ethanol E85. This is currently the most effective way of reducing your fuel budget, and Shiftech is the No. 1 expert in this field in France.

One of the first questions asked by drivers considering E85 conversion is: "Will I find E85 near me? The answer is clearly yes.

• 93% of French people live less than 10 km from a service station that distributes Superethanol E85
• More than 4,500 service stations in France offer E85, including the major brands TotalEnergies, BP, Shell, Esso, etc
• Supermarkets (E.Leclerc service stations, Intermarché, Carrefour, Auchan) widely distribute E85, often at the best prices
• Vinci, Sanef and ASF motorway service stations are gradually introducing E85 into their networks
• The prix-carburants.gouv.fr application can be used to locate the cheapest E85 station around you in real time.

E85 has become a mainstream fuel, available in all major cities and rural areas. There's no longer any logistical reason not to take the plunge.

Stage 1 reprogramming for diesel

Diesel fuel has undergone the most brutal increase in March 2026: +32 centimes per litre in just a few weeks, reaching an average of €2.22 per litre nationwide. For diesel drivers, who are often long-distance commuters, the impact on their monthly budgets is considerable.

The good news for diesel vehicle owners is that Stage 1 engine reprogramming is one of the most effective solutions for reducing fuel consumption. Unlike E85 conversion for petrol engines, Stage 1 diesel has a direct effect on fuel combustion efficiency.

Stage 1 diesel reprogramming affects several key ECU parameters: common rail pressure, injection curves, turbo management and ignition delay. The result is an engine that develops more torque at lower revs, which means in practice that you change gear earlier and the engine doesn't need to rev as high to maintain your cruising speed.

• Smoother engine, less stress in traffic jams
• Less jerking and acceleration, naturally lower fuel consumption
• Up to 10% savings on actual consumption observed by our customers
• Improved performance: safer overtaking, better hill-holding
• Compatible with the vast majority of recent diesel vehicles

For a vehicle consuming 6L/100km and travelling 20,000 km/year, a 10% reduction represents annual savings of around €270 at current diesel prices. Stage 1 reprogramming often pays for itself in less than a year.
