Valvoline announced the launch of its new passenger car motor oil formulas for both the U.S. and Canada. The company said these formulas surpass the updated International Lubricant Standardization and Approval Committee (ILSAC) GF-7 standards, which formally went into effect on March 31.
Valvoline added that its current ILSAC GF-6 certified synthetic

The company said its engine lab in Ashland, Ky. allows Valvoline to perform critical engine sequence tests that help define industrywide performance requirements every five to seven years. “These days, everything seems to move just a little bit faster, and our engines have to work even harder to keep up with the pace of our busy lives,” said Dr. Michael Warholic, senior global technology director at Valvoline Global Operations. “By helping car owners maintain their vehicles’ performance and longevity, Valvoline’s dedication to the development of the ILSAC GF-7 standards is protecting engines not just for today, but for the needs of tomorrow as well, delivering improved performance levels in almost every area.”
link hidden, please login to view said its ILSAC GF-7 full synthetic technology was tested in a single engine for over 500,000 miles across three years without the need to replace any critical component, while significantly reducing sludge and deposits compared to an ILSAC GF-6 quality oil. The ILSAC GF-7 specification continues the A and B designations started with the ILSAC GF-6 upgrade in 2020. The ILSAC GF-7A designation applies to all SAE 0W-20 viscosity grades and heavier. ILSAC GF-7A is backward compatible with all previous GF-6A, GF-5 and older ILSAC specifications. The ILSAC GF-7B designation applies to SAE 0W-16 viscosity grade oils and is backward compatible to ILSAC GF-6B only.
As ILSAC GF-6 designated motor oils are phased out of distribution channels after the March 31, 2025, GF-7 launch, Valvoline said its new motor oils meeting the ILSAC GF-7A standard will include the “Starburst” API mark on all bottles, while ILSAC GF-7B-compliant oils will have the API “Shield.” Oils meeting API SP will feature an updated API “Donut” with SP designation.
“Advances in engine oil performance wouldn’t be possible without the dedication, expertise and leadership of our Valvoline engineers and scientists, who work tirelessly to help define and shape the industry standards, continually raising the bar to benefit us all,” said Warholic.

If you’ve ever looked into car engine management systems, you’ve probably come across the terms ECM (Engine Control Module) and ECU (Engine Control Unit). While these terms are often used interchangeably, they are not exactly the same. Understanding the difference between ECM and ECU can help you diagnose vehicle issues, make informed repair decisions, and ensure your car runs efficiently.
At Clifford Auto Parts, we specialize in high-quality ECMs and ECUs, providing affordable replacements with free shipping across the USA. In this blog, we’ll break down the key differences between ECMs and ECUs, their roles in vehicle performance, and how to know when it’s time to replace them.
✅ What is an ECU (Engine Control Unit)?
The Engine Control Unit (ECU) is a broad term referring to any electronic module that controls various aspects of a vehicle's operation. Modern cars often have multiple ECUs that manage different systems in the vehicle, such as:
✔️ Engine Management (ECM) – Controls fuel injection, ignition timing, and emissions.
✔️ Transmission Control (TCM) – Regulates automatic gear shifting.
✔️ Brake Control (ABS Module) – Manages anti-lock braking systems.
✔️ Body Control (BCM) – Controls lighting, windows, and climate systems.
The ECU acts like the brain of the car, receiving signals from sensors and making real-time adjustments to optimize performance, efficiency, and safety.
✅ What is an ECM (Engine Control Module)?
The Engine Control Module (ECM) is a specific type of ECU dedicated to managing the engine’s performance. It ensures the correct amount of fuel, air, and spark is delivered to keep the engine running smoothly.
A faulty ECM can cause serious performance issues, including:
✔️ Check Engine Light Staying On
✔️ Engine Stalling or Misfiring
✔️ Poor Fuel Efficiency
✔️ Starting Problems
At Clifford Auto Parts, we offer tested and warrantied ECM replacements for Ford, Dodge, Jeep, Chrysler, and more, ensuring a plug-and-play experience for vehicle owners across the USA.
✅ How Do ECM and ECU Work Together?
While the ECM specifically controls the engine, it still communicates with other ECUs in the car. For example:
✔️ The ECM and TCM (Transmission Control Module) work together to ensure smooth gear shifting.
✔️ The ECM and BCM (Body Control Module) coordinate engine start functions with security and lighting systems.
✔️ The ECM interacts with the ABS Module to adjust power delivery during emergency braking situations.
Modern cars rely on these interconnected systems to provide seamless driving performance.
✅ When Should You Replace Your ECM or ECU?
If your vehicle is experiencing engine trouble, transmission issues, or persistent warning lights, you may need to replace the ECM or a specific ECU. Some warning signs include:
✔️ Check Engine Light stays on, even after repairs
✔️ Sudden drops in fuel efficiency
✔️ Rough idling, stalling, or misfires
✔️ Transmission shifts erratically or gets stuck in a gear
✔️ Car fails to start despite a working battery
Ignoring these symptoms can lead to costly repairs. The best way to diagnose the problem is to use an OBD-II scanner to check for ECU or ECM-related fault codes.
✅ Why Choose Clifford Auto Parts for ECM & ECU Replacements?
At Clifford Auto Parts, we specialize in providing high-quality, reliable ECM and ECU replacements that fit seamlessly into your vehicle. Here’s why thousands of vehicle owners trust us:
✔️ Wide Selection: We offer ECMs & ECUs for Ford, Jeep, Dodge, Chrysler, and more.

✅ Final Thoughts
Understanding the difference between ECM and ECU helps car owners diagnose vehicle problems, make informed repair decisions, and ensure long-term performance. While ECUs control multiple car functions, ECMs specifically manage the engine’s performance.
If you're facing engine issues, poor fuel efficiency, or transmission troubles, it may be time to replace your ECM or another ECU module. At Clifford Auto Parts, we provide tested, warrantied, and affordable ECMs and ECUs to keep your vehicle running like new.
