Hot Off the Press

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...

The Misunderstood Ford 6.0

My wife and I are RVers and started our RV adventure with a 23’ toy hauler. When we started, we pulled the trailer with a Ram 1500 equipped with the 5.7-liter Hemi engine, and for most outings, it handled the task just fine. It wasn’t until we took a trip to the North...

Side Business

If your shop is a typical one, you wouldn’t turn down easy, profitable work, right? Of course not. Maybe it’s time your foreman, techs, and service writers sat down and talked through the car that isn’t a car: side-by-side (SxS). Like other not-immediately-obvious...

Power and Ground Testing on an Electrical Circuit

I'll never forget this one day in the shop. One of the other techs was wrestling with an electrical gremlin and swung by my bay for some backup. "Pete, mind giving me a hand? I've got this GMC pickup with a blower motor that's running super slow. I checked the power...

ADAS Repairs: Why Calibration Is A Must

Modern vehicles equipped with Advanced Driver Assistance Systems (ADAS) are truly marvels of engineering. What started as high-end options found only on luxury cars can now appear as standard equipment on some econo-boxes (e.g., blind spot detection). That means it is...

Sergio Pininfarina: Sculpting Speed and Beauty in Metal (Part 2)

In Part 1 of this piece, we looked at Sergio Pininfarina’s career up to 1987. In this part, we’ll take a look at his innovative concept cars. Concept cars: when art defied convention Sergio encouraged his designers to explore new ideas through concept vehicles that...

The Only Thing Better Than Making Money Is Not Losing It

Service writers, this piece is aimed squarely at you. You may be aware of many of the costs of doing business. Recognizing potential costs and preventing them from eating into your shop’s productivity is one of the skills that separates a good writer from an...

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!
