Using Valvoline motor oil will keep your manufacturer’s warranty valid – in most instances – backed by law.
The Magnuson-Moss Warranty Act prohibits manufacturers from voiding your warranty simply because you used an aftermarket product, including motor oil, as long as it meets your vehicle’s specifications. (Refer to your owner’s manual for any exceptions.) Valvoline’s lineup, from Advanced Full Synthetic to Restore & Protect, meets or exceeds the API SQ and ILSAC GF-7A standards that most automakers require, so you’re covered on both fronts.
The Magnuson-Moss Warranty Act, a federal consumer protection law in place since 1975, prohibits manufacturers from conditioning your warranty on the use of a specific brand of replacement product, including motor oil, unless they provide that product to you for free. The Federal Trade Commission enforces this.
It’s possible that a manufacturer denies a claim if they can prove the product caused the failure in your engine. But with most automakers, that shouldn’t be an issue if you use the Valvoline oil that meets your vehicle’s published specifications.
You can use Valvoline oil and still enjoy the benefits of your vehicle’s warranty. This is one of the most common misconceptions among car owners.
What Do "API SQ" and "ILSAC GF-7A" Actually Mean?
Knowing about these standard certifications will help you stay within the coverage limits for your vehicle warranty. These are the quality certifications that automakers point to when they specify
API SQ is the American Petroleum Institute’s current standard for gasoline engine oils. It was developed in cooperation with the major automakers and addresses the critical demands of modern engines, including turbocharger protection, chain wear, LSPI (low-speed pre-ignition) prevention, and deposit control. When an oil displays the API "Donut" symbol with "SQ," it has been tested to meet those standards.
ILSAC GF-7A is the companion specification from the International Lubricants Standardization and Approval Committee. GF-7A oils carry the familiar API "Starburst" symbol on the bottle. The latest standards call for more stringent motor oil protection and performance levels compare to GF-6 in numerous areas, including:
- Fuel economy and fuel economy retention
- Engine durability
- Wear protection
- Low-speed pre-ignition reduction in both new and aged oils
- Piston cleanliness
- Timing chain wear protection
Valvoline announced in 2025 that its oils meet or exceed the GF-7A standard, providing better wear protection than industry requirements.*

GM Dexos, and Does Valvoline Meet It?
If you drive a GM vehicle, Chevy, GMC, Buick, or Cadillac, built after 2011, your owner’s manual likely calls for a dexos-certified oil. Dexos is GM’s own enhanced specification.
GM developed Dexos to address the specific demands of its modern engines, including fuel efficiency targets, emissions compliance, LSPI prevention in turbocharged engines, and resistance to piston deposits. An oil must pass a series of GM-specific laboratory and engine tests before it can carry the dexos license.
Select grades of Valvoline Advanced Protection Full Synthetic and Valvoline Extended Protection Full Synthetic motor oil are dexos 1 Gen3 licensed by GM. That means you’re not sacrificing warranty protection to use it. You’re using an oil that has been tested and approved to the exact standard your vehicle requires.

Does Valvoline Offer an Engine Protection Guarantee?
Valvoline’s approach to engine protection is built into the product itself, not a separate warranty. When you use an oil that meets your vehicle’s specifications and API SQ / ILSAC GF-7A industry standards, like Valvoline Advanced Protection Full Synthetic Motor Oil, you’re using a product that has been independently tested to deliver that protection.
Valvoline Restore & Protect takes this further with a first-of-its kind formula designed to remove up to 100% of engine deposits with continued use*. Learn more about Restore & Protect at the Restore & Protect product page.
*When used as directed for four or more consecutive oil changes and with continuous use. In Adapted Sequence IIIH testing. Piston Deposit Removal.
Documenting My Oil Changes to Protect My Warranty
In order to stay covered by your vehicle warranty, you need to record your oil changes and any other maintenance your vehicle receives. The Magnuson-Moss Act protects your right to use aftermarket oil, but if a warranty dispute ever arises, you want solid records showing you maintained your vehicle properly.
Here’s what good documentation looks like:
- Keep every receipt. Whether you buy oil at an auto parts store or online, save the receipt. It shows the product name, viscosity grade, and purchase date.
- Record the mileage. Note your odometer reading every time you do an oil change, either on the receipt itself, in a small notebook kept in the glove box, or in a simple phone note or spreadsheet.
- Note the date. Date plus mileage together tells the complete story of your maintenance history.
- Keep the oil filter box or packaging. The filter brand and part number can matter if a claim involves filtration-related engine damage.
- Take a photo. A quick phone photo of the oil container, filter, and odometer reading takes 30 seconds and creates time-stamped digital proof.
If you use a shop for oil changes, ask for a printed service receipt every time - and keep them. Most quality shops include the oil brand, viscosity grade, filter part number, mileage, and date on every invoice. That receipt is your warranty shield.
For DIY oil changers using Valvoline full synthetic oils, the receipts already show that an API SQ / ILSAC GF-7A certified product was purchased. Pair that with a mileage log, and you have the documentation that covers you.
Check If Valvoline Is Compatible with My Specific Car’s Requirements
You can look up in your owner’s manual if Valvoline oil fits the specifications for your vehicle. Valvoline oil is compatible with most passenger cars and light trucks on the road. Valvoline’s full synthetic lineup covers the API SQ / ILSAC GF-7A specification that applies to virtually every major automaker’s gasoline engine requirements: Toyota, Honda, Ford, GM, Stellantis (Chrysler, Dodge, Jeep, Ram), Hyundai, Kia, Subaru, Volkswagen, and
Select grades of Valvoline Advanced Protection Full Synthetic and Valvoline Extended Protection Full Synthetic motor oil are dexos 1 Gen3 licensed by GM.
The key is always to match the viscosity grade your owner’s manual specifies, whether that’s 0W-20, 5W-30, or another grade, and to choose an oil that carries that meets API / ILSAC standards. Valvoline offers multiple viscosity options across its product lines.
Valvoline Warranty FAQ
Can using Valvoline oil instead of another oil void my warranty?
In most cases, under the Magnuson-Moss Warranty Act, a manufacturer cannot void your warranty simply because you used Valvoline oil. They can only deny a specific claim if they can prove the oil you used directly caused the failure. Using an API SQ / ILSAC GF-7A that meets the manufacturer’s specifications typically satisfies the requirements for most automakers. Check your owner’s manual for details.
Does Valvoline oil meet GM Dexos requirements?
Select grades of Valvoline Advanced Protection Full Synthetic and Extended Protection Full Synthetic motor oil are dexos 1 Gen3 licensed, which is the current GM requirement for most post-2011 GM vehicles. This includes many Chevrolet, GMC, Buick, and Cadillac engines that call for a Dexos-approved oil.
What should I look for on a motor oil bottle to protect my warranty?
Oils that meet ILSAC GF-7A will display the API “starburst.” Oils that meet the API SQ standard will feature the updated API “Donut” with the SQ designation. Valvoline’s full synthetic oils carry both.
What is the best Valvoline oil for a new car still under factory warranty?
If you are in the market for Valvoline oil for your new car, Valvoline Advanced Protection Full Synthetic Motor Oil in the viscosity grade specified by your owner’s manual may be the right choice. It meets or exceeds API SQ, ILSAC GF-7A standards covering specifications from most major automakers.
