Excessive oil consumption in my 2016 Chrysler 200 with Pentastar V6

Vehicle: 2016 Chrysler 200C

My 2016 Chrysler 200C, equipped with the 3.6L Pentastar V6 engine, seems to be burning through oil way too fast. I'm having to add a quart or more between oil changes, sometimes as early as 3,000 miles after a fresh oil change. It's concerning because my previous cars never did this.

There's no visible leak under the car, and I haven't seen any blue smoke from the exhaust, which usually indicates oil burning. I keep a close eye on the dipstick now, but it feels abnormal.

Is this level of oil consumption normal for the Pentastar engine, or could it be a bigger problem? I'm worried about engine longevity and potential damage if this continues. What should I be looking for?

ClearTheCode admin answer:

Excessive oil consumption in the 3.6L Pentastar V6 engine, particularly in earlier iterations (like those found in 2011-2017 models), has been a documented concern for some owners. While a small amount of oil consumption is normal for any engine, needing to add a quart or more every 3,000 miles is generally considered excessive.

Here are potential causes and steps:

  1. PCV (Positive Crankcase Ventilation) Valve: A faulty or clogged PCV valve can lead to increased crankcase pressure, forcing oil past piston rings or valve seals. This is a relatively inexpensive component to replace and a common culprit for oil consumption without visible leaks.
  2. Valve Guides/Seals: Worn valve guides or seals can allow oil to seep into the combustion chamber. This can be a more involved repair.
  3. Piston Rings: In more severe cases, worn or stuck piston rings can lead to oil blow-by and consumption. This is a major engine repair.
  4. Oil Filter Housing: While typically causing external leaks, a cracked oil filter housing (common on some Pentastar engines) could potentially lead to some oil loss, though usually it's visible.
  5. TSBs and Recalls: Check with a Chrysler dealership for any Technical Service Bulletins (TSBs) or recalls related to oil consumption for your specific VIN. Chrysler did issue revised PCV valves and had specific diagnostic procedures for oil consumption.

What to do:

  • Oil Consumption Test: A Chrysler dealership can perform an official oil consumption test. This involves topping off the oil, sealing the dipstick and fill cap, and having you return after a certain mileage to measure consumption and determine if it meets criteria for repair.
  • Regular Checks: Continue to check your oil level regularly (every 1,000-1,500 miles) and top off as needed to prevent engine damage.

When to See a Shop:

  • As soon as possible to get an accurate diagnosis. Ignoring excessive oil consumption can lead to lubrication issues, premature wear on engine components, and potentially catastrophic engine failure. A professional can identify the source of the consumption and recommend the appropriate repair.
