Chevrolet Onix Oil Capacity & Oil Type
TL;DR
Gen-1 naturally aspirated Onix (1.0/1.4, 2012-2019) takes roughly 3.5 L of 5W-30 with filter; the newer 1.0 Turbo (2019-present) takes roughly 3.75 L of 5W-30 Dexos1 Gen3. Figures vary slightly by source, so verify with your dipstick and owner's manual.
Chevrolet Onix oil capacity - which engine do you have?
The Onix is built and sold mainly in Brazil and across Latin America, and that Brazilian-market car is the version covered here (North American and other markets may use different engines). Capacity and viscosity depend heavily on which engine generation is under the hood, so the first step is identifying your engine code and model year rather than assuming one figure fits every Onix.
Figures found in service references
For the first-generation Onix (2012-2019) with the naturally aspirated 1.0 SPE/4 or 1.4 8V engines, independent Brazilian oil-service references consistently list a capacity of about 3.5 liters with the filter changed, using 5W-30 oil meeting the API SN / Dexos1 standard.
For the current-generation Onix and Onix Plus (2019-present) with the 1.0 turbo three-cylinder engine, service references list a capacity of about 3.75 liters with filter, using 5W-30 oil meeting the Dexos1 Gen3 / API SP standard. Some listings for related naturally aspirated 1.0 versions of the newer platform mention 0W-20 instead, so the turbo and non-turbo variants of the same generation are not identical - check which one you actually have.
Data table
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 1.0 SPE/4, 8V (2012-2019, Gen 1) | 3.5 L / 3.7 US qt | 5W-30 API SN, Dexos1 |
| 1.4 8V Econoflex (2012-2019, Gen 1) | 3.5 L / 3.7 US qt | 5W-30 API SN, Dexos1 |
| 1.0 Turbo, 3-cylinder (2019-present, Gen 2 / Onix Plus) | 3.75 L / 4.0 US qt | 5W-30 Dexos1 Gen3, API SP |
| 1.0 naturally aspirated, current platform (2019-present) | Not independently confirmed - check dipstick/manual | Some references cite 0W-20 Dexos1 Gen3 |
Why you should still check your own car
Even within one engine family, running changes and market-specific tunes can shift the exact fill volume by a few hundred milliliters. The figures above are the best corroborated numbers found in independent service sources, not manufacturer-guaranteed data for every build date.
- Check the label under the hood near the oil filler cap - it usually states capacity and viscosity directly.
- Check your owner's manual maintenance section for the exact factory-fill specification.
- Ask a Chevrolet dealer to confirm using your VIN if you plan a precise refill.

Frequently asked questions
How much oil does a Chevrolet Onix need with a filter change?
It depends on the engine. The naturally aspirated 1.0 SPE/4 and 1.4 8V engines used from 2012 to 2019 take about 3.5 liters (3.7 US quarts) with the filter changed. The 1.0 turbo three-cylinder engine used from 2019 onward takes about 3.75 liters (4.0 US quarts) with filter. Confirm the figure for your specific engine before refilling.
What oil viscosity does the Onix use?
The older naturally aspirated engines (2012-2019) typically specify 5W-30 meeting API SN and GM Dexos1. The newer 1.0 turbo engine (2019-present) typically specifies 5W-30 meeting Dexos1 Gen3 and API SP. Some naturally aspirated versions of the current platform are listed with 0W-20 instead, so check your own filler cap or manual to be certain.
Where can I find the exact oil specification for my Onix?
The most reliable sources are on the car itself: the sticker near the oil filler cap or under the hood, and the maintenance section of the owner's manual. These are matched to your exact build and are more reliable than any general online guide, including this one.
Is the oil capacity different between the Onix hatchback sold in Brazil and versions sold elsewhere?
This page covers the Brazilian and Latin American market Onix, which is the primary production version of this model. If your Onix was sold under a different badge or market with a different engine lineup, the capacity and viscosity could differ, so match the engine code rather than just the model name.
