Real results from a real shop. 🏭

One of our customers was struggling with cutting oil that couldn't keep up on stainless steel — running slow, burning through inserts, and losing time on every job.

After switching to Truegard SWISS #148, they're now getting full-shift tool life on 304 and 316 SS — and cutting cycle times almost in half. It even handles brass and copper without staining.

The right lubricant isn't just a supply line item. It's a productivity decision.

SCR system faults don’t usually start as major failures.
They start as small issues that get ignored: Low-quality DEF, contamination, or early-stage crystallization.

Then the warning lights show up.
Then the derates.
Then the downtime.

For fleets and diesel techs, an SCR system fault isn’t just a nuisance—it directly impacts uptime, emissions compliance, and operating costs. And in many cases, the root cause traces back to DEF handling and quality.

The teams that avoid these issues aren’t reacting to fault codes; they’re preventing them. They understand how SCR systems work, how DEF impacts performance, and how to catch problems before they escalate.

We put together a practical guide breaking down what an SCR system fault actually means, the most common causes, and how to fix and prevent it.

Worth a read if you’re responsible for keeping trucks on the road.

Brake jobs going sideways? It might not be your parts.

It might be what you’re cleaning them with. 👈

A lot of shops still treat carb cleaner and brake cleaner like they’re interchangeable. They’re not. And using the wrong one can lead to contaminated pads, reduced stopping power, and damaged components.

The difference between carb cleaner vs. brake cleaner comes down to formulation, residue, and purpose—and it directly impacts safety and your shop’s reputation. If you’ve ever grabbed the wrong can in a rush, our new article is worth a quick read.

Check out the full breakdown to make sure your team is using the right cleaner.

Wondering what the differences are between carb cleaner vs. brake cleaner? Our experts break down when to use each and how to avoid costly mistakes.

As machining shops ramp up production, coolant management becomes one of the most powerful and often overlooked levers for performance.

TRUEGARD SUPERCOOL #4086 is a semi-synthetic coolant engineered to remain stable under real-world shop conditions:

• Bio-stable formulation that helps reduce bacteria growth and odor
• No sulfur-based emulsifiers, so it doesn’t “feed” contamination
• Resists mixing with hydraulic and way oil, making tramp oil easier to remove
• Ultra-low foaming, even in high-pressure CNC applications
• Polyester-enhanced performance for both steel and aluminum machining

The best shops don’t just react to coolant problems—they manage them proactively.
