Maintaining the correct oil capacity and using the proper oil type in your 2008 Chevy Colorado is crucial for engine longevity and optimal performance. Whether you own the 4-cylinder or 5-cylinder variant, this comprehensive guide provides all the specifications you need for your next oil change.
We’ll cover factory-recommended oil types, exact capacity measurements, and a step-by-step oil change procedure to help you maintain your truck properly.
Recommended Oil Type for 2008 Chevy Colorado
Using the correct oil type is essential for your Colorado’s engine health. The factory specifications provide clear guidelines on what oil will work best for your specific engine.
Factory-Recommended Oil Specifications
Engine | Recommended Viscosity | Oil Standard |
2.9L 4-cylinder | 5W-30 | API SM or newer |
3.7L 5-cylinder | 5W-30 | API SM or newer |
The viscosity rating of 5W-30 is ideal for most climate conditions your Colorado will encounter. The “5W” indicates how the oil flows in cold temperatures, while “30” refers to its thickness at normal operating temperature.

Synthetic vs. Conventional Oil
Conventional Oil
- Lower initial cost
- Adequate for normal driving conditions
- Requires more frequent changes (3,000-5,000 miles)
- Less effective in extreme temperatures
- Standard protection against engine wear
Synthetic Oil
- Higher initial cost but better long-term value
- Superior performance in extreme temperatures
- Extended change intervals (7,500-10,000 miles)
- Better protection against engine deposits
- Improved fuel efficiency
While conventional oil meets the minimum requirements for your 2008 Colorado, synthetic oil offers better protection and longevity, especially for trucks used in demanding conditions or extreme climates.

2008 Chevy Colorado Oil Capacity Details
Knowing the exact oil capacity for your specific engine is crucial to avoid underfilling or overfilling during an oil change. The 2008 Chevy Colorado comes with two engine options, each with different oil capacity requirements.
Engine Type | Oil Capacity (with filter) | Oil Capacity (quarts) | Oil Capacity (liters) |
2.9L 4-cylinder | Yes | 5 quarts | 4.7 liters |
3.7L 5-cylinder | Yes | 6 quarts | 5.7 liters |

Important: The capacities listed above include the oil filter. When performing an oil change, always check the dipstick after adding the specified amount to ensure the oil level is within the acceptable range (between the hash marks on the dipstick).
Understanding Dipstick Readings
As discussed in Colorado owner forums, the dipstick reading can sometimes be confusing. For the most accurate reading:
- Park your truck on level ground
- Wait at least 5 minutes after shutting off the engine (ideally check when cold after sitting overnight)
- Remove the dipstick, wipe it clean, reinsert it fully, then remove again to check
- The oil level should be between the two hash marks on the dipstick
- If the level is at the bottom hash mark, you’re approximately 1 quart low
Get the Right Oil Filter
Using a quality oil filter is just as important as using the right oil. The ACDelco Professional Engine Oil Filter is designed specifically for your Chevy Colorado.

Tools and Materials Needed

- Socket wrench set (including 15mm socket for drain plug)
- Oil filter wrench
- Drain pan (minimum 6-quart capacity)
- Funnel
- Shop rags or paper towels
- New oil filter
- 5-6 quarts of 5W-30 oil (depending on your engine)
- Disposable gloves
- Jack and jack stands (if needed for access)
Oil Change Procedure
- Prepare the vehicle: Run the engine for 5 minutes to warm the oil. Then park on level ground, engage the parking brake, and let the engine cool for 10 minutes.
- Access the underside: If necessary, safely jack up the front of the truck and secure it with jack stands.
- Locate the drain plug: Position your drain pan under the oil pan drain plug, located on the bottom of the engine oil pan.
- Drain the oil: Using your socket wrench, carefully loosen the drain plug counterclockwise. Once loose, finish removing it by hand and allow all oil to drain completely (about 5-10 minutes).
- Replace the drain plug: Clean the drain plug and reinstall it, tightening to 18 ft-lbs (if you have a torque wrench) or until snug plus a quarter turn.
- Remove the old oil filter: Locate the oil filter and use an oil filter wrench to loosen it counterclockwise. Finish removing it by hand, being careful of hot oil that may drain out.
- Prepare the new filter: Apply a thin film of new oil to the gasket of the new filter.
- Install the new filter: Screw the new filter on by hand until the gasket contacts the mounting surface, then tighten an additional 3/4 turn.
- Add new oil: Remove the oil fill cap on top of the engine and use a funnel to add the specified amount of oil (5 quarts for 4-cylinder, 6 quarts for 5-cylinder).
- Check for leaks: Replace the oil fill cap, start the engine, and let it run for a minute. Check for any leaks around the oil filter and drain plug.
- Verify oil level: Turn off the engine, wait 5 minutes, then check the oil level with the dipstick. Add more oil if needed.
- Dispose of old oil properly: Take your used oil to a local auto parts store or recycling center for proper disposal.

Safety Warning: Never work under a vehicle supported only by a jack. Always use proper jack stands. Hot oil can cause severe burns, so allow the engine to cool before beginning the oil change procedure.

Oil Maintenance Tips for Your 2008 Chevy Colorado
Proper oil maintenance extends beyond just changing the oil. Follow these tips to keep your Colorado’s engine running smoothly for years to come.
Recommended Oil Change Intervals
Normal Driving Conditions
- Conventional oil: Every 3,000-5,000 miles
- Synthetic oil: Every 7,500-10,000 miles
- Or follow your owner’s manual recommendation
Severe Driving Conditions
- Frequent short trips (less than 10 miles)

Signs of Using Incorrect Oil
Using the wrong oil type or running low on oil can lead to various issues. Watch for these warning signs:
- Increased engine noise: Knocking, ticking, or rattling sounds may indicate inadequate lubrication
- Reduced fuel efficiency: Incorrect viscosity can increase friction and reduce MPG
- Oil pressure warning light: Indicates low oil level or pressure issues
- Overheating: Oil helps regulate engine temperature
- Burning smell: May indicate oil is leaking onto hot engine components
- Dark, dirty oil: Oil that quickly turns black after a change may indicate engine issues

Regular Oil Level Checks
Even between oil changes, it’s important to regularly check your oil level:
- Check oil level at least once a month
- Always check before long trips
- If you notice any oil spots under your vehicle, check the level immediately
- Keep a quart of the correct oil in your truck for top-offs when needed
Frequently Asked Questions About 2008 Chevy Colorado Oil
Can I use 10W-30 instead of 5W-30 in my 2008 Chevy Colorado?
While 5W-30 is the recommended oil viscosity for your 2008 Colorado, 10W-30 can be used as a temporary substitute in warmer climates if 5W-30 is unavailable. However, 10W-30 provides less protection during cold starts, so it’s best to return to the manufacturer-recommended 5W-30 at your next oil change. Never use a viscosity that’s not listed in your owner’s manual.
What happens if I overfill the oil in my Colorado?
Overfilling your engine oil by more than half a quart can cause serious problems. Excess oil can be aerated by the crankshaft, creating foam that doesn’t lubricate properly. This can lead to increased engine pressure, oil leaks, damaged seals, and in severe cases, engine damage. If you’ve overfilled, safely drain the excess oil until the dipstick shows the proper level.
Is a specific oil filter required for the 2008 Chevy Colorado?
While you don’t need to use the OEM AC Delco filter, it’s important to use a quality filter that meets or exceeds OEM specifications. For the 2008 Colorado, use filter part numbers AC Delco PF46, Wix 57060, NAPA 1060, or equivalent. Using a low-quality filter can lead to poor filtration, reduced oil pressure, and potential engine damage.
How do I reset the oil life monitor after an oil change?
To reset the oil life monitor in your 2008 Chevy Colorado: 1) Turn the ignition to ON (don’t start the engine), 2) Press the gas pedal to the floor three times within five seconds, 3) The “CHANGE OIL SOON” message should flash and then disappear, 4) Turn the ignition off. If this doesn’t work, consult your owner’s manual as procedures can vary slightly between model years.
Why does my 5-cylinder Colorado take more oil than the 4-cylinder version?
The 3.7L 5-cylinder engine in your Colorado has a larger displacement and more internal components than the 2.9L 4-cylinder engine, requiring additional oil for proper lubrication. The 5-cylinder takes 6 quarts while the 4-cylinder takes 5 quarts. Always use the correct amount specified for your particular engine to ensure proper lubrication and prevent damage.
