- Correction. This page previously said the Fiat 500 does not have a combustion engine and therefore does not require engine oil. That is true of the 500e only. The 500 Hybrid has been on UK sale throughout this period alongside it, and it needs oil like any petrol car.
- On the specification code. Some third-party oil guides quote Fiat 9.55535-GS1 for this engine. The owner’s handbook gives 9.55535-DM1. Buy against DM1, and check the code on the bottle rather than relying on the grade alone.
How to tell which car you have: the 500e has no exhaust pipe, a charge flap on the rear offside wing and 500e badging. The Hybrid has a conventional exhaust and a manual gearbox with a clutch pedal.
Confidence in this data: High. The grade, the Fiat specification code and the capacity all come from the Fiat 500 Hybrid owner’s handbook, and are corroborated by the trade catalogue entry for the 312 mild hybrid.
Checked against: the Fiat 500 Hybrid owner’s handbook (technical specifications and capacities), Fiat UK’s current model range, and the TecDoc-derived catalogue entry for chassis 312.
Frequently Asked Questions
What engine oil does a Fiat 500 need?
It depends which Fiat 500 you have. The 500 Hybrid (series 312, the 1.0 FireFly mild-hybrid petrol) takes 0W-20 meeting Fiat specification 9.55535-DM1 and ACEA C5, and holds 2.5 litres including the filter. The 500e (series 332) is battery-electric and takes no engine oil at all.
Is the Fiat 500 electric?
Only one of them is. Fiat sells the electric 500e (series 332) and the petrol 500 Hybrid (series 312) side by side in the UK, and has done throughout this period. An earlier version of this page said the Fiat 500 is fully electric, which was wrong.
Can I use 5W-30 in a Fiat 500 Hybrid?
Not as a routine substitute. The engine is specified for a 0W-20 oil meeting Fiat 9.55535-DM1 and ACEA C5, which is a low-viscosity, low-SAPS specification the engine and its emissions hardware are calibrated around. A 5W-30 that does not carry that approval is not an equivalent, whatever else the bottle claims.
How much oil does a Fiat 500 Hybrid take?
2.5 litres including the filter, or 2.2 litres for the sump alone, per the owner’s handbook. Fill to the dipstick rather than tipping in a fixed measure.
Does an electric car need any fluids?
Yes. The 500e still needs brake fluid, coolant for the battery thermal management system and screenwash, all on the schedule in the handbook. What it does not need is engine oil, because there is no engine.
How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
