6.2 LS Engine Oil Capacity(+ Best Recommended Oils)

The 6.2-liter LS engine has become one of the most popular high-performance engines in the GM lineup, powering everything from sports cars to full-size trucks.

Below is everything you need to know about oil capacity, viscosity recommendations, and maintenance tips for this engine family.

6.2 LS Engine Oil Capacity

The 6.2 LS engine oil capacity is 8 quarts (7.6 liters) with a new oil filter installed, which applies to popular 6.2 LS variants like the LS3, L92, L99, L94, and other GM truck and performance versions.

These engines typically use 5W-30 full synthetic oil, though 0W-40 or 5W-40 is recommended for heavy-duty or high-performance driving.

Always verify the level on the dipstick after filling, especially if the engine has an aftermarket oil pan, and follow a 5,000–7,500-mile oil change interval for normal driving or shorter intervals for towing, off-road use, or modified engines.

LS3	Gen IV LS	6.2L	8 qt / 7.6 L	5W-30 Synthetic	Corvette, Camaro SS, Pontiac G8 GXP
L92	Gen IV LS	6.2L	8 qt / 7.6 L	5W-30 Synthetic	Escalade, Yukon Denali, Suburban 6.2
L99	Gen IV LS	6.2L	8 qt / 7.6 L	5W-30 Synthetic	Camaro SS (Automatic)
L94	Gen IV LS	6.2L	8 qt / 7.6 L	5W-30 Synthetic	Escalade, Silverado/Sierra 6.2
L9H	Gen IV LS	6.2L	8 qt / 7.6 L	5W-30 Synthetic	Silverado/Sierra 1500
LSA	Gen IV LS (Supercharged)	6.2L	8.9 qt / 8.4 L	5W-30 Synthetic	CTS-V, Camaro ZL1 (1st Gen)
LS9	Gen IV LS (Supercharged)	6.2L	10.5 qt / 9.9 L	5W-30 Synthetic	Corvette ZR1

Many performance owners upgrade to high-flow synthetic filters, especially for LS3 and L99 engines running extended oil change intervals.

Recommended Oil Type for a 6.2 LS Engine

GM recommends SAE 5W-30 full synthetic oil for most 6.2 LS applications, especially LS3 and L99 engines. For heavy-duty use, extreme performance, or towing, some owners upgrade to 5W-40 synthetic for better high-temperature stability.

Typical recommended specs include:

SAE 5W-30 full synthetic (daily driving)
SAE 0W-40 or 5W-40 full synthetic (track, towing, off-road)
Oil that meets GM Dexos1 Gen 2, where applicable

If the engine is modified, cammed, boosted, or stroked, oil requirements may shift slightly, but 8 quarts remains the standard capacity.

Why Oil Capacity Matters for 6.2 LS Engines

The LS engine family is known for high RPM potential, strong bottom ends, and excellent cooling, but only when properly lubricated. Running the correct amount of oil helps:

Maintain stable oil pressure
Cool internal engine components
Lubricate bearings and valvetrain parts
Prevent excessive wear under high load
Reduce oil breakdown during hard driving

Underfilling or overfilling may cause foaming, pressure fluctuations, or even bearing damage over time. The 6.2 LS engines have tight tolerances, so keeping the oil level correct is essential.

How Often Should You Change Oil in a 6.2 LS Engine?

Oil change intervals depend on how the engine is used:

Normal driving: every 5,000–7,500 miles
Towing, off-roading, hot climates: every 3,500–5,000 miles
Performance/track use: every 1,500–3,000 miles
E85 vehicles: slightly shorter intervals due to fuel dilution

Even though modern synthetic oils last longer, the LS platform benefits from fresh oil because of its performance-oriented design.

Signs Your 6.2 LS Needs an Oil Change

Watch for the following:

Rough idle or ticking noises
Drop in oil pressure
Dark, gritty, or thin oil
Engine running hotter than usual
Oil smell from the engine bay
Excessive piston slap noise

Ignoring these signs reduces engine life, especially if the vehicle is modified or driven aggressively.

6.2 LS Engine Oil Change Tips

Follow these to ensure accurate filling:

Always replace the oil filter during service.
Add 7 quarts first, start the engine briefly, shut off, then top off to 8 quarts based on the dipstick.
Warm the engine before final measurement, LS engines read more accurately when hot.
Use a torque wrench on the drain plug (typically 18–20 ft-lb depending on the pan).
Check the oil level regularly if the engine is modified or tuned.

FAQs

How much oil does a 6.2 LS take?
