How many quarts of oil does a Chevy Sonic take?
In short, it depends on the engine. The 1.8-liter engine uses about 5 quarts of oil with a filter, while the 1.4-liter turbo uses about 4.5–4.8 quarts. Always verify with the owner's manual for your exact model year and engine code.
The Chevrolet Sonic was offered with two common engines during its production: a 1.8-liter inline-four and a 1.4-liter turbocharged inline-four. Oil capacity numbers can vary slightly by year, trim, and whether you’re changing the filter. Use the Dexos1 Gen2 5W-30 specification as a starting point, and consult the window sticker or owner's manual for the exact figure.
Engine variants and oil capacity
Capacity figures by engine are summarized below. Note that some model years may require a slightly different amount due to changes in oil capacity and filter size.
- 1.8L inline-4 engine: approximately 4.5–5.0 quarts of oil with a new filter installed.
- 1.4L turbocharged inline-4 engine: approximately 4.5–4.8 quarts of oil with a new filter installed.
These figures are starting points. For precise capacity, check the owner's manual or GM service information for your exact model year and engine code, and ensure you replace the oil filter during a full change.
Oil type and maintenance tips
Most Sonic engines use Dexos1 Gen 2 approved 5W-30 motor oil. Always confirm the exact specification for your year and engine, and follow GM's recommended service intervals (typically a full oil change every 5,000–7,500 miles depending on driving conditions).
Summary
The Chevy Sonic's oil capacity hinges on the engine. The 1.8-liter version commonly requires about 4.5–5 quarts with a filter, while the 1.4-liter turbo usually needs about 4.5–4.8 quarts. Always consult the owner's manual or GM service information for your exact vehicle and use the recommended Dexos1 Gen 2 5W-30 oil. Regular checks with the dipstick help ensure proper level between changes.
