PSA: The Right (and Wrong) Ways to Handle Iridium Spark Plugs

For the vast majority of vehicles on the road, swapping out spark plugs is gravy work. Yoink the old plugs, make sure the replacements meet the necessary gap spec, install the new plugs, and button up the ignition system. You’re in and out of there in no time, right?...

Try Doing It the Wrong Way

Today’s article is composed of two quick tips that are distinct and different, but interrelated because they’re used on the same items: the humble fasteners we remove and install hundreds of times daily. These tips are both geared to newer techs since we all must find...

Modern Power Window Switches: Smarter than You’d Think

When was the last time you rolled down the power windows in an older car or truck? I’m talking at least pre-2000. The older, the better. As a passenger, you’ll find that every door has a mix of buttons, switches, locks, and handles to mess around with, plus maybe a...

It’s All About the Process

Man, it feels like just yesterday you graduated with that Associate’s in Automotive Tech, but nope, it's been three months already, and you've landed a solid job at ABC Auto Repair back in your hometown. The boss has been taking it easy on you, dishing out a bunch of...

Dealing with “System Lean” DTCs

The Engine Control Module (ECM) is always keeping an eye on the amount of fuel it is adding to the cylinders, and it'll throw a code when it figures it can't keep the mixture right where it needs to be. You might see codes like "system rich" or "system lean," and they...

Back Away from the Wrenches

Today’s article is more of a philosophical one than a pragmatic one. You see, we’re in the business of buying and reselling auto parts, servicing automobiles, and getting paid for our efforts. But as automotive professionals, we merely delay the inevitable. The...

Best of Shop Press 2025

by | Dec 30, 2025

Another year is in the books here at Shop Press, and we thought we’d take this time to look back at 2025’s most notable articles, videos, and more. Here’s what you (and we) loved this year on Shop Press as we head into 2026.

Most-viewed overall

Our most-viewed post overall is a Pete Meier post: his “Are you servicing your car’s oil correctly?” article stirred up plenty of engagement and discussion. It seems many of you were interested in Pete’s treatise covering how to avoid some common (and expensive) mistakes when it comes to oil changes. In the article, Pete identified missed oil changes and the use of incorrect oil types as the primary causes of engine failure. He emphasized the importance of strictly following manufacturer guidelines for specific oil formulations and using high-quality filters to protect modern engines, as well as recommending annual oil changes and regular level checks to ensure vehicle longevity.

Most-viewed video post

Our most-viewed video post of this year was “Top tips for car and truck fleet maintenance: what repair shops need to know.” Apparently, many of you are ready to grow your shop’s business with fleet maintenance, service, and repairs. In the video, Chris from Dayton Parts and Lemmy from Dorman Products explained that while fleet work often involves tighter margins, it provides repair shops with crucial stability through consistent, simpler maintenance jobs that fill schedule gaps. They emphasized that these vehicles require strict “severe duty” maintenance due to high usage, but the tradeoff is streamlined communication and predictable volume that keeps technicians busy.

(Second) most-viewed article

Our second most-viewed article this year was “PSA: Stop throwing away brake rotor screws.” In the article, Lemmy pointed out two reasons to keep these little screws instead of tossing them. For vehicles with lug bolts (e.g., German, Fiat, Chrysler), these screws keep the rotor aligned with the hub, making wheel installation easier. And for most other vehicles, the retaining screw ensures the rotor is perfectly positioned and held in place during assembly.

Rounding out the Top 10

Once again, readers clearly appreciated the “how to” and concrete, real-world, wrenching advice pieces, because many such articles and videos appear throughout our Top 10. The 2025 list includes:

Staff picks

We don’t just love writing for Shop Press; we love reading it, too. Here were some of our personal favorites.

Andy had a couple he liked this year. In his words, “I liked the Hansville Repair piece for the glimpse into what must be one of the more remote shops in the United States. There are some unique challenges that come with truly being the only game in town.”

He also enjoyed our “Stress Test Vehicle Grounds” piece. As he said, “That’s largely because it saved me some diag time! The reminder to test grounds was just what I needed before digging into an intermittent starter problem. Guess what was to blame?”

Some other personal favorites of the Shop Press team:

Thanks for reading Shop Press this year and (hopefully) enjoying our articles and videos for mechanics and the mechanically-inclined. We have more great stuff to come in 2026!
