About Josh Malczak
I'm an industrial lubrication specialist based in Mercer County, Pennsylvania. I've spent five years working only on lubricants, after ten years in sales and sixteen years as a police officer, and I help plants, shops and fleets in 14 counties keep their equipment running.

What I do
Most of my week is spent in plants, machine shops, quarries and fleet garages: walking equipment, looking at lube rooms, pulling oil samples and talking with the people who keep things running. I supply the lubricants, but most of the value comes from getting the right product into each machine, keeping it clean, and changing it at the right time.
How I work
- Answer fast. A down machine doesn't wait, so I don't either.
- Start with the equipment. I look at what you run and how before I recommend anything.
- Keep it simple. Fewer products, clear labels and intervals your techs can follow.
- Be honest. If what you have is working, I'll say so.
Background
I've lived in Mercer County for more than 20 years. Before lubricants, I spent 16 years as a police officer and sold everything from tires to cigars. Police work teaches you to show up when you're called, stay calm when something is broken, and tell people the truth. All three carry straight over to keeping a plant or a fleet running.
Results I'm proud of
- Helped a large Pennsylvania municipality extend oil drain intervals on its equipment.
- Helped a local industrial plant double the drain intervals on its power generation engines.
Longer drain intervals mean less oil bought, less waste oil hauled away and less downtime, as long as the oil is proven to hold up. Here's how that's done safely.
Who I work for
This is my personal site, where I write about what I see in the field. Products and services are supplied through my employer, a national chemical and lubricant distributor. Views on this site are my own.
Let's talk about your equipment
Tell me what you run and what's giving you trouble. I'll come out, walk the equipment, and give you a straight answer on what would help, whether or not you end up buying anything.
