If you're adding oil between changes on your 2019 Chevrolet Equinox, you're not alone. The 1.5L turbocharged engine in this model year has developed a reputation for oil consumption that frustrates owners and sometimes leads to expensive repairs.
What's Considered Normal vs. Excessive
GM's official stance is that consuming up to 1 quart per 2,000 miles is within "normal" parameters. However, many 2019 Equinox owners report consumption rates exceeding this—some adding a quart every 1,000 miles or less. At that rate, you're essentially doing oil changes between oil changes.
Signs of Oil Consumption
- Oil level dropping noticeably between changes
- Low oil pressure warning light
- Blue or gray smoke from exhaust (especially on startup)
- Oil smell inside or outside the vehicle
- Fouled spark plugs
- Engine running rough due to low oil
Why the 1.5L Turbo Burns Oil
Several factors contribute to this engine's thirst:
- Piston ring design: The low-tension rings designed for efficiency may not seal adequately
- PCV system issues: The positive crankcase ventilation system can pull oil into the intake
- Turbocharger seals: Worn turbo seals allow oil into the exhaust or intake
- Valve stem seals: Degraded seals let oil past the valves
- Extended oil change intervals: These engines don't tolerate long intervals well despite oil life monitor suggestions
What You Can Do
- Document consumption: Check oil weekly and keep a log of additions with dates and amounts
- Shorten oil change intervals: Consider 5,000 miles maximum instead of relying on the oil life monitor
- Use the right oil: Stick with dexos1 approved 5W-30 full synthetic
- Request a consumption test: Your dealer can perform an official oil consumption test
- Check for TSBs: Service bulletins exist for PCV valve updates and other fixes
Repair Options and Costs
- PCV valve replacement: $100-$200
- Valve stem seal replacement: $500-$1,200
- Turbocharger rebuild or replacement: $1,500-$2,500
- Piston ring replacement: $2,500-$4,500 (essentially an engine rebuild)
- Engine replacement: $5,000-$8,000
If your Equinox is still under powertrain warranty and fails GM's consumption test, internal repairs may be covered.
