When it comes to maintaining a Smart car’s engine, choosing the right oil is critical. Many drivers lean toward full synthetic oils with European specifications because the small, high-revving engines in Smart models often demand better protection under heat and stress.
Below are five smart choices of engine oils that are commonly recommended by mechanics or used by Smart car owners.
Smart Car Engine Oil Type
1. Mobil 1 FS European Car Formula 0W-40
Mobil’s European Car Formula is a full synthetic oil popular among owners of European and micro European vehicles. It offers strong protection across a wide range of operating temperatures, making it a safe bet for Smart models with tighter tolerances and occasional high-stress use.
Key Features:
- Broad temperature range with excellent cold start behavior
- Resists oxidation, sludge, and deposit formation
- Strong shear stability to maintain viscosity under load
- Supports longer drain intervals (as recommended by the manufacturer)
- Meets multiple European OEM specifications
2. AMSOIL 5W-40 FS European Motor Oil
AMSOIL’s 5W-40 formulation is designed for European and high-performance engines. It is a fully synthetic oil that balances protection and flexibility, and it is sometimes used in Smart cars where 5W-40 is an acceptable viscosity.
Key Features:
- Strong film strength under high load
- Good cold-start viscosity with high-temperature stability
- Tailored to European car needs with strict tolerance requirements
- Low volatility, reducing oil consumption
- Enhanced additives to reduce wear and deposits

Choosing the Right Oil for Your Smart Car
When selecting oil for your Smart car, keep these points in mind:
- Owner’s Manual Guidance – Smart models often specify viscosity ranges such as 0W-30, 0W-40, 5W-30, or 5W-40, and may require oils that meet European specifications.
- Climate – In hot climates or under heavy highway use, 0W-40 or 5W-40 provides extra protection. In milder regions, 0W-30 or 5W-30 can reduce friction and improve efficiency.
- Oil Change Intervals – Some oils are designed for extended drain intervals, but it’s still important to check oil condition regularly.
- OEM Approvals – Always confirm that the oil you choose meets required manufacturer or European standards.
- Brand Reliability – Sticking with trusted brands ensures consistency and performance.
FAQs
What oil does a smart car use?
Most Smart cars use full synthetic oil with viscosities such as 0W-40, 5W-40, 0W-30, or 5W-30, depending on the model and year. Always follow the owner’s manual recommendations.
What kind of oil does a 2015 smart car take?
The 2015 Smart Fortwo typically requires 0W-40 full synthetic motor oil that meets European specifications. This provides excellent protection for its small, high-revving engine.
What kind of oil does a 2013 smart car take?
A 2013 Smart Fortwo usually takes 0W-40 full synthetic oil. In some climates, 5W-40 may also be acceptable if recommended by the manufacturer.
What kind of oil does a 2002 smart car take?
