Full Synthetic Protection for Modern Engines

Engine oil is subjected to extreme conditions every time you drive.

Cold starts require oil to circulate quickly through narrow passages. Once the engine reaches operating temperature, that same lubricant must resist thinning, oxidation and deposit formation while maintaining a protective film between rapidly moving components.

Quaker State Full Synthetic is engineered with high resistance to oxidation, helping the lubricant remain effective as it encounters repeated heat cycles.

That’s particularly useful in modern engines where turbochargers, variable valve timing systems and tighter internal tolerances can place additional demands on engine oil.

Reduced Friction for Efficient Performance

Quaker State designed its Full Synthetic formula to reduce friction compared with its conventional motor oil.

Less unnecessary internal friction can help an engine operate efficiently while allowing the lubricant to protect bearings, cylinder walls, valvetrain components and other internal surfaces.

Quaker State also states that its Full Synthetic formulation provides improved fuel economy based on current industry testing standards.

No, pouring it into the crankcase won’t magically add 100 horsepower.

But reducing unnecessary friction inside an engine is generally preferable to creating more of it.

Helps Fight Sludge and Harmful Deposits

Combustion byproducts, heat, moisture and oil degradation can contribute to deposits inside an engine over time.

Quaker State Full Synthetic is formulated to provide excellent protection against sludge and harmful deposit formation, based on applicable Sequence IIIH and VH testing.

Keeping deposits under control is particularly important for engines equipped with small oil passages, hydraulic timing components and turbocharger lubrication circuits.

Excellent Cold-Temperature Lubrication

The 5W portion of the SAE 5W-20 viscosity rating relates to the oil’s low-temperature performance.

Quaker State Full Synthetic is designed to provide strong lubrication flow and pumpability across both high and low temperatures.

That is especially valuable during startup, when oil needs to circulate quickly to critical components.

Once operating temperature is reached, the SAE 20 operating viscosity provides the characteristics required by engines specifically designed for 5W-20 motor oil.

Always use the viscosity specified by your vehicle manufacturer.

Designed for Turbocharged Engines

Turbochargers can expose engine oil to considerable heat.

The turbocharger shaft can operate at extremely high rotational speeds while relying on engine oil for lubrication and heat management. That makes resistance to oxidation and deposits particularly important.

Quaker State Full Synthetic is specifically formulated for today’s sophisticated engines, including modern turbocharged applications.

Whether your vehicle is naturally aspirated or boosted, verify that SAE 5W-20 and the applicable specifications are approved for your exact engine before use.

Always consult your owner’s manual for the required viscosity, specification, oil capacity and service interval.

API SP and ILSAC GF-6A Protection

Quaker State Full Synthetic 5W-20 meets API SP Resource Conserving and ILSAC GF-6A requirements.

These modern oil standards are particularly relevant to contemporary gasoline engines and include requirements addressing areas such as wear, oxidation, deposits, fuel economy and protection against low-speed pre-ignition in applicable engines.

The oil also meets Ford WSS-M2C960-A1 and Chrysler MS-6395, making it suitable for numerous applications requiring those specifications.

Compatibility should always be determined by the requirements listed for the specific vehicle and engine—not simply because “5W-20” appears on both bottles.

Up to 300,000-Mile / 10-Year Quaker State Warranty

Eligible users of Quaker State motor oil may qualify for the company’s lubrication limited warranty offering coverage for up to 300,000 miles or 10 years, whichever comes first, subject to Quaker State’s enrollment requirements, vehicle eligibility, maintenance requirements and other terms.

Quaker State also advertises a Cash Back Program based on an eligible vehicle’s Kelley Blue Book trade-in value, with benefits up to $3,000, subject to program requirements.

Vehicle eligibility restrictions apply, including mileage and vehicle-age requirements. Enrollment, qualifying oil changes, documentation and other conditions may also be required.

Check the current Quaker State Full Synthetic product and warranty information before relying on warranty coverage.

Who Should Buy Quaker State Full Synthetic 5W-20?

This oil is a strong option for drivers whose vehicle manufacturer specifies SAE 5W-20 and whose engine requires specifications supported by this formulation.

It makes particular sense for:

• Modern daily-driven gasoline vehicles
• Turbocharged engines requiring compatible 5W-20 oil
• Performance-oriented street vehicles
• Pickup trucks and SUVs
• Family cars and minivans
• Drivers upgrading from conventional oil
• Owners concerned about oxidation and deposit control
• Vehicles requiring Ford WSS-M2C960-A1
• Vehicles requiring Chrysler MS-6395
• Applications calling for API SP / ILSAC GF-6A 5W-20 oil

A Smart Full-Synthetic Choice for Your Next Oil Change

Engine oil isn’t the glamorous part of a build.

Nobody opens the hood at Cars & Coffee and says, “Dude, show me that crankcase.”

But the expensive parts everyone actually wants to see depend on proper lubrication.

Quaker State Full Synthetic 5W-20 Motor Oil delivers a practical combination of full-synthetic protection, low-temperature performance, oxidation resistance, friction reduction and deposit control for compatible engines.

If your owner’s manual specifies the correct 5W-20 viscosity and supported specification, grab a 5-quart jug and give your engine the protection it was designed to run on.
