Electric, Hybrid & Alternative Fuels

Track electric, hybrid, LPG, CNG, and dual-fuel (bi-fuel) vehicles in My Cars

Does My Cars support electric vehicles?

Yes. My Cars isn’t just for petrol and diesel cars — it tracks electric, hybrid, LPG, CNG, ethanol/flex-fuel and dual-fuel vehicles. You set the fuel type when you add a vehicle, and the app adapts its units and calculations to match.

How do I set my vehicle’s fuel type?

  1. Add or edit a vehicle (Menu > Vehicles)
  2. Choose the Fuel type that matches your car
  3. Save

From then on, your refuels (or charges) and efficiency figures use the right units for that fuel.

Choosing a fuel type, including LPG, CNG and dual-fuel options

Tracking an electric car (EV)

For electric vehicles, log your charges the same way you’d log a refuel — the energy you added (in kWh) and what it cost. Efficiency is shown in electric units such as:

  • kWh/100km or kWh/100mi — energy used per distance
  • kWh/h — for time-based usage

This lets you see your real running cost per kilometre or mile, just like fuel efficiency for a combustion car.

Tracking a hybrid

Hybrids that run on petrol (or diesel) are tracked like a combustion car — log your fuel-ups and the app reports fuel efficiency and costs. If your vehicle also charges from the grid as a plug-in, use the dual-fuel option below to record both energy sources.

Tracking LPG and CNG

LPG (autogas) and CNG (compressed natural gas) are fully supported, including the appropriate units:

  • LPG is measured in litres (or gallons), like liquid fuel
  • CNG is measured by volume (e.g. m³/100km, m³/100mi)

Set the vehicle’s fuel type accordingly and log each fill-up as usual.

Tracking a dual-fuel (bi-fuel) vehicle

If your car runs on two fuels — for example petrol + LPG, or petrol + CNG — My Cars can track both. A bi-fuel vehicle has two tanks, and each refuel lets you record the quantity and price for the fuel you actually filled.

  • Record a petrol fill and an LPG fill independently
  • See costs and efficiency for each fuel
  • Advanced efficiency settings let you choose how combined efficiency is calculated

Your CO₂ savings (trees saved)

If you drive an electric or plug-in hybrid vehicle, the Dashboard can show how much CO₂ you’ve avoided compared with an equivalent petrol car. Add the CO₂ Savings card to your Dashboard — it’s free, in the Summary group — and it shows:

  • CO₂ saved — kilograms of CO₂ avoided over the selected period
  • Distance driven on electric power, and your real efficiency (kWh/100km)
  • ≈ N trees — your savings expressed as the number of trees needed to absorb that much CO₂ in a year
  • Lifetime total — your all-time CO₂ saved

The CO₂ Savings dashboard card showing kilograms saved and the equivalent number of trees

The card appears once you’ve logged some electric charges. For petrol or diesel vehicles it stays hidden — it shows “Available for electric and plug-in hybrid vehicles.”

How is it calculated?

My Cars uses your actual EV efficiency (from your logged charges) and your region’s grid carbon intensity to estimate real EV emissions, then compares that to a reference petrol car:

  • Grid carbon intensity (g CO₂/kWh) — auto-detected from your region; adjust it to match your local electricity mix
  • ICE car reference (g CO₂/km) — the petrol car you’re comparing against (the EU fleet average is 120)

Both are adjustable under CO₂ Calculation Settings, so the figure reflects how and where you actually charge.

Which fuel types are supported?

My Cars supports, among others:

  • Petrol / Gasoline
  • Diesel
  • Electric
  • Hybrid (petrol + electric) and diesel hybrid
  • LPG (autogas)
  • CNG
  • Ethanol / flex-fuel
  • AdBlue (as an additive expense)
  • Dual-fuel / bi-fuel (two-tank) vehicles

You can also customize fuel subtypes and octane grades to match what’s sold in your region.
