How many quarts does a 2006 HHR take?
The 2006 HHR’s oil capacity depends on which engine it uses: about 4.5 quarts for the 2.2L and about 5 quarts for the 2.4L, including the filter.
Engine options and oil capacity
The HHR was offered with two four-cylinder engines in the 2006 model year. Here are the typical engine oil capacities for each engine, including the oil filter.
- 2.2L Ecotec I4 (L61): 4.5 quarts (4.3 L) with filter.
- 2.4L Ecotec I4 (LD9/LE5 family common in HHR): 5.0 quarts (4.7 L) with filter.
Capacities are for standard oil changes with a filter replacement. If you use a different filter size or perform a dual-fluid service, the numbers may slightly vary.
Choosing oil and maintenance tips
Use the correct viscosity and follow the recommended maintenance interval. For most 2006 HHRs, 5W-30 is the standard grade, with synthetic options acceptable for extended drain intervals depending on climate and driving conditions. Always confirm the exact specification from the owner's manual or under-hood labeling if available.
Oil grade and additives
Recommended oil grade is typically 5W-30 (conventional or synthetic). If you live in very cold climates, a thinner grade like 0W-30 may improve cold starts; in hot climates, 10W-30 is sometimes used but check the manual.
Checking and topping oil
Before checking, run the engine briefly, then park on level ground and wait for the oil to settle. Use the dipstick to verify the level. If low, add small amounts (1/2 quart at a time) and recheck until the dipstick reads within the full range.
What to do if you’re unsure
If you’re unsure which engine your HHR has, consult the VIN or the window sticker, or check under-hood labeling near the engine bay. This ensures you use the correct oil capacity for your vehicle.
Summary
Bottom line: 2006 HHR oil capacity depends on the engine. The 2.2L engine takes about 4.5 quarts with filter; the 2.4L engine takes about 5 quarts with filter. Use a 5W-30 oil, perform regular oil changes, and verify level with the dipstick after a warm engine restart. When in doubt, reference the owner's manual or dealership.
