Unusual Oil Consumption in 2018 S60 T5 - Is This Normal?

Vehicle: 2018 Volvo S60 T5 Momentum

Hi all,

I've got a 2018 Volvo S60 T5 with about 70,000 miles on it. Lately, I've noticed it's been consuming a significant amount of oil between oil changes. I check the oil level regularly via the Sensus screen (no dipstick, which is annoying), and it seems to drop about a quart every 3,000-4,000 miles.

There are no visible leaks on my driveway, and I don't see any blue smoke from the exhaust. The car runs fine, no warning lights or performance issues. Is this level of oil consumption normal for the T5 engine in these models, or should I be concerned? What could be causing this if it's not normal?

Any insights from other S60 T5 owners would be great.

ClearTheCode admin answer:

While some oil consumption is considered normal for any internal combustion engine, a quart every 3,000-4,000 miles on a 2018 Volvo S60 T5 with 70,000 miles is on the higher side of what's typically expected for a well-maintained engine without visible leaks or smoke. Volvo's official stance often allows for up to 1 quart per 1,000 miles, but this is usually an extreme maximum.

Here are potential causes and steps:

  1. PCV System Issues: A common culprit for increased oil consumption without visible leaks is a malfunctioning Positive Crankcase Ventilation (PCV) system. If the PCV valve or associated hoses are clogged or failing, pressure can build up in the crankcase, forcing oil past piston rings or valve seals. This can lead to oil being burned in the combustion chamber.
  2. Turbocharger Seals: The T5 engine is turbocharged. Worn or failing turbocharger seals can allow oil to leak into the exhaust or intake side of the turbo, where it's then burned or consumed. This might not always produce visible blue smoke, especially if the leakage is minor and consistent.
  3. Valve Stem Seals: Over time, valve stem seals can harden or wear out, allowing oil to seep past them into the combustion chambers, particularly during engine startup or deceleration.
  4. Piston Rings: While less common at 70,000 miles unless the engine has been poorly maintained, worn or stuck piston rings can also contribute to oil consumption. Carbon buildup can cause rings to stick.
  5. Oil Type/Viscosity: Ensure you are using the correct oil type and viscosity specified by Volvo (e.g., synthetic 0W-20 or 5W-30, depending on the specific engine variant and region). Incorrect oil can sometimes lead to higher consumption.

When to See a Shop:

You should schedule an appointment with a Volvo specialist or dealership for a diagnostic check. They can perform:

  • PCV System Test: To check for proper crankcase ventilation.
  • Compression and Leak-Down Test: To assess the condition of piston rings and valves.
  • Turbocharger Inspection: To check for oil residue in the intake/exhaust.
  • Oil Consumption Test: Some dealerships will perform a controlled oil consumption test, where they mark the oil level, and you return after a specified mileage for re-evaluation.

Early diagnosis can prevent more significant engine issues down the line.
