The National Institute for Automotive Service Excellence (ASE) said more than 8,400 automotive service professionals participated in its gasoline engine survey. ASE has been commissioned to conduct a series of studies to identify and understand which repair tasks automotive service technicians perform most frequently.
The initial survey focused on gasoline engine repair tasks and showed that 57% of those who completed the survey are currently A1 certified or were in the past, and 76% hold one or more ASE A2-A8 automotive certifications. A majority of those respondents hold each of those respective certifications.
Regarding training, technicians receive training from a variety of sources including on the job (79%), OEM training (69%), college (57%), high school (53%) and aftermarket (47%). Among those who completed the survey, 82% said they have 10 or more years of experience and 57 percent said ASE certifications factored into their pay plans.
As a thank you to those who participated in the survey, five automotive service professionals were randomly selected to be awarded Snap-on gift cards. The winners are Andrew Cronin Sr., David Kaplanis, Jeramy Peterson, David Phillips and Calen Sober-Throop.

When diagnosing engine performance complaints such as misfire symptoms, be advised that several systems and components can contribute to those symptoms. When considering single or multiple misfire codes, some checks may seem farfetched but trust me if not all are considered the symptoms can elude the most experienced technician, resulting in a misdiagnosis. When this […]

Theory can only take you so far when formulating engine oil. Complex modeling is an important step, but it can’t duplicate the magic that happens inside the cylinder. Operating conditions, duty cycles, driver behavior—it all impacts how an engine ages. As it does, deposits form within the engine. The carbonaceous compounds that form on various engine components, including pistons, valve trains, and timing chain covers are a natural occurrence; a consequence of aging that result from the breakdown of oil components at high temperatures, particularly during the combustion process. The highest temperatures occur on the metal surfaces within the engine, where these deposits tend to adhere.
“There are some deposits that are temporary that you can wipe off with your finger, and there are others that can get very thick,” explained Dr. Michael Warholic, global technology director, Valvoline Global Operations. “The bad thing about deposits—and actually there are several bad things—are that, first of all, they insulate and you can’t get the heat out.
“They also cause friction.”
Friction is exceptionally bad, especially if you’re formulating oil. Thick deposits can clog oil passages, restricting the flow of oil to critical engine parts. This leads to inadequate lubrication, exacerbating wear and potentially causing engine failure. Traditionally the role of engine oil has been to slow down engine deposit development, but in concocting its latest engine-protecting blend, the Valvoline team stumbled upon something … surprising.
“We were trying to basically minimize deposits, engine wear, friction and heat, and oil formulation is a balance, so you have to pick and choose what you want it to do,” Warholic explained. “What we didn’t know was before the testing that it would remove and reverse the process–that is something you can’t predict by modeling. Restore and Protect removed engine deposits.
“I had never seen anything like it before, and I have eight years at Valvoline and 16 years at a company that makes the additives used in oil formulation.”
Valvoline’s Restore and Protect is a fully synthetic motor oil that aims at both older, high-mileage vehicles (restore) and new vehicles (protect). While Warholic was tight-lipped about the specific blend of additives within the oil, Valvoline has noted two proprietary technologies–Active Clean, which removes deposits and Liqui-Shield, which prevents deposit formation.
It’s not just marketing—at a recent event, Valvoline put Restore and Protect-cleaned pistons on display. Take a look:
Valvoline validates its oils through industry standard tests such as the GF-6 SP specification, which uses a Chrysler Pentastar engine to measure deposit formation. These tests provide a benchmark for oil performance, ensuring that the oil meets or exceeds industry requirements.
“Exceeds” is the key word. Warholic was quick to point out that these types of tests are merely the baseline within the oil market, not the high bar that oil manufacturers should seek to leap over.
“We want to exceed the API specifications and excel in all categories. Restore and Protect is already GF-7 capable, which is great,” he said.
Real-world testing is crucial. For instance, a Ford Mustang was subjected to extensive testing with Restore and Protect, showing significant reductions in wear and deposit formation. The testing extended to various engine components, including the timing chain cover, oil pan, and valve train, demonstrating the comprehensive benefits of the oil. The team also ran Restore and Protect in a Ford Explorer with more than 500,000. “And we also did a chassis dynamometer test where we put a vehicle on rollers basically and ran it 300,000 miles,” Warholic said. “Restore and Protect actually cleaned up the entire engine.”
For automotive aftermarket professionals, understanding the use of high-performance oils can lead to better engine health, improved engine operating efficiency, reduced maintenance costs and happy customers.
“We’re trying to maximize engine life,” Warholic said. “Vehicles are getting older. The vehicle life on the road is getting older. Vehicles may change owners and engines are going to be running longer. For us, it’s about maximizing engine performance so that you don’t lose fuel economy, you don’t lose efficiency, and you don’t break down on the highway.”
