What Oil Does a 2020 Chevrolet BLAZER Take?

Choosing the correct motor oil for your BLAZER’s 2.5L LCV engine is crucial for fuel economy, smooth operation, and engine longevity. The manufacturer’s recommended oil viscosity and type are:

• 0W-20 Full Synthetic (All Temperatures): The only viscosity grade recommended by GM. 0W-20 ensures fast cold starts, reliable flow at low and high temps, and maximizes engine protection year-round.

Using a high-quality full synthetic 0W-20 meets GM’s stringent requirements and helps prevent sludge and premature wear—whether you drive in freezing winters or blazing summers.

2020 Chevrolet BLAZER Oil Capacity

The engine oil capacity for the 2020 Chevrolet BLAZER 2.5L LCV is exactly 5 quarts (with filter change). Always check the dipstick after filling, ensuring the oil sits in the safe zone, as overfilling can cause leaks, foaming, or even engine damage. After topping up or changing the oil, idle the engine for a minute, then recheck the dipstick for an accurate reading.

How Often Should You Change the Oil on a 2020 Chevrolet BLAZER?

For the 2020 Chevrolet BLAZER, the manufacturer recommends an oil change interval of up to 7,500 miles or 12 months, whichever comes first, when using full synthetic oil like 0W-20. If you use conventional oil (not recommended), it should be changed every 3,000-5,000 miles. Driving habits—or severe conditions like frequent short trips, towing, or hot/cold climates—may require more frequent changes. Signs like a lit oil life monitor, darkened oil, or noisy engine mean you should change sooner.

Oil Filter for the 2020 Chevrolet BLAZER

The oil filter protects your Chevrolet BLAZER’s engine by trapping debris and particles from the circulating oil. For the 2.5L LCV engine, Costa Oil uses the COF1403 oil filter, designed to match OEM specifications for efficiency and flow. A high-quality filter is essential—generic, off-brand filters can clog prematurely or fail to seal. Choose professional-grade filters for reliability, or opt for Costa Oil’s COF1403 specifically engineered for your car.
