link hidden, please login to view announced that Jeff Koviak will assume the role of CEO effective January 1, 2025, replacing retiring CEO Larry Pavey.
link hidden, please login to view is a joint partnership between the Federated Alliance and The Pronto Network, and is made up of 300 member companies with over 5,000 locations and 80,000 employees primarily in North America. In his new role, Koviak will be dedicated to driving strategic initiatives for The Group membership that “will maximize future revenue growth while simultaneously streamlining internal systems and resources to reduce redundancy throughout the organizations,” according to a news release announcing his appointment.
“We feel Jeff is the ideal candidate to move The Group toward the original goal of strategically unifying the traditional aftermarket partners while still respecting the unique strengths that each of the individual groups offer in their marketplace,” said Sue Godschalk, president of Federated Auto Parts.
“Jeff comes to us with an exceptional background,” added Robert Roos, president and CEO of The Pronto Network. “During his 30-year career at Tenneco/DRiV, he built strong, long-term, trusting relationships with all of our members, and we are excited to have him join forces with our teams.”

There is nothing simple about complex engine oil formulations. Effectively explaining to your customer how Valvoline’s Restore & Protect motor oil removes and prevents engine deposits may seem like a tough task.
Dr. Michael Warholic, global technology director for Valvoline Global Operations, emphasizes the importance of visual evidence
“Hey, look how this product performs,” said Warholic. “We have visuals showing that there’s a removal of deposits, that there is a reversing of the aging process in an engine. That’s a great case story to tell.”
Warholic talks with Babcox Content Director Jason Morgan about the formulation process that sets Restore & Protect apart. The process involves a balance of various additives and components, tested rigorously in both laboratory and real-world conditions. It also involves combining base oils, viscosity modifiers, and a unique blend of additives. These additives include detergents to clean deposits, friction modifiers to reduce engine strain, and antioxidants to combat the breakdown of oil components. The goal was to create a motor oil that not only prevents the formation of new deposits but also removes existing ones, effectively rejuvenating the engine.
“We wanted to do something different than everybody else,” said Warholic. “That’s what Restore and Protect does. It differentiates us from our competitors. It does something that no other oil does in the marketplace right now.”
Restore & Protect could be considered a new category of motor oil that bridges the gap between conventional oils and high-mileage formulations. While high-mileage oils are designed for older engines, Restore & Protect is suitable for both new and aging engines. Its dual function of preventing new deposits and reversing existing ones makes it a versatile choice for a wide range of vehicles.
This innovation is particularly valuable for engines operating under severe conditions, such as those used for towing or in high-traffic areas. The oil’s ability to handle these demanding environments while maintaining engine cleanliness offers a significant advantage over standard motor oils.
“There’s always engine oil. Formulating is a little bit about give and take. The engine is a very complex machine. You have different temperatures, different pressures. It is really a very interesting field when you start digging into it.”
“We do tons of data-driven testing. That’s what we live for.”

General Motors released its dexos1 oil specification in 2011. It came about as part of an initiative to create a global oil specification to ensure consistent oil quality for engine development and production. This would also reduce the number of resources it took to maintain the multiple different specifications they had at the time.
The testing required to meet the original dexos1 specification was a combination of some of the most rigorous tests in the industry. GM found that oils that didn’t meet the new dexos1 specification could affect engine performance and potentially cause engine damage, and as a result, not using it in a new GM vehicle that specified it could affect the engine warranty.
link hidden, please login to view During this time, low speed pre-ignition (LSPI) was becoming a problem with modern small displacement, direct injected, turbo charged engines. Heavier loads on these smaller engines were partly to blame for the increase in LSPI, but it was also discovered that certain detergents in the engine oil contributed to the problem, leading to the development of new engine oil chemistries.
Another oil related challenge involved the widespread use of variable valve timing (VVT) systems, which require that engine oil acts as a hydraulic fluid. When used in these applications, air in the system will severely affect their operation, and resistance to aeration became a prevalent factor for motor oils.
So, in 2015, GM introduced the dexos1 Gen 2 specification. This improved upon oxidation and deposit control, and this new oil met a new series of tests, including an LSPI test and a test measuring the oils resistance to aeration.
The current dexos1 Gen 3 standard reflects a further reduction in oil degradation and deposit formation, as well as improved sludge control. Dexos1 Gen 3 oils are backwards compatible and acceptable for use where dexos1 and dexos1 Gen 2 is called for.
Only licensed dexos products are vertified by GM to meet the dexos specifications. There are many engine oils which meet these specifications, and they can be easily identified, but there are two markings which must be present on an oil that meets the dexos specification. One is the dexos icon on the front label and the other is an 11-digit alphanumeric dexos license number which will be located on the back label. If an oil does not display both of these markings, it does not meet the dexos specification.
Dexos2 was an original formulation that met the requirements for many gasoline and light duty diesel engines, but it is being discontinued in 2025 and replaced by dexos D for diesel engines and dexos R for gasoline engines. Dexos D is formulated for use in light duty diesel engines and is backward compatible for use in anything that previously called for dexos2.
The latest dexos specification is dexos R, which is designed to withstand the punishment of high speed and high load conditions, such as those created during high performance driving. Certain new vehicles require it, such as the Corvette. Dexos R is backward compatible and can be used in any gasoline engine that calls for dexos2, dexos1 Gen 2 or dexos1 Gen 3 oil.
