How to Keep Your Skid Steers and Excavators Running Strong with Regular Oil Changes

Why Oil Changes Matter for Your Equipment

Oil is the lifeblood of any piece of construction equipment. It keeps your engine running smoothly by reducing friction between moving parts. Over time, oil breaks down and gets dirty. When that happens, your skid steers and excavators have to work harder, which can lead to expensive repairs and unexpected downtime on the job site.

Regular oil changes are one of the simplest ways to extend the life of your equipment and keep it running strong. Think of oil changes as preventive maintenance—a small effort now that saves you from major problems later. Engines that get regular oil changes last longer, perform better, and cost less to maintain over their lifetime.

Understanding Your Equipment's Oil Change Schedule

Every skid steer and excavator is different. The manufacturer sets a recommended oil change schedule based on how the machine is built and what it's designed to do. This schedule is your starting point for keeping your equipment in good working order.

Your equipment manual will tell you:

• How often to change the oil (usually measured in hours of use)
• What type and grade of oil to use
• How much oil your machine needs
• Where to find the drain plug and filter
• The oil capacity and specifications for your specific model

Most skid steers need an oil change every 250 to 500 hours of operation. Excavators often follow a similar schedule, though this can vary based on the model and engine size. Some larger excavators might go longer between changes, while smaller or older models might need more frequent service. Always check your specific machine's manual to be sure.

The hour meter on your equipment is your best tool for tracking when service is due. Unlike vehicles that track miles, construction equipment tracks operating hours, which gives you a more accurate picture of engine wear and tear.

Factors That Affect How Often You Change Oil

The recommended schedule is a starting point, but real-world conditions matter. Some situations mean you may need to change oil more often than the manufacturer suggests. Understanding these factors helps you make smart decisions about your maintenance routine and avoid unexpected breakdowns.

• Dusty or dirty job sites: Dust and dirt can get into your oil faster, making it less effective at protecting engine parts. Construction sites with a lot of excavation or demolition work create extra dust that can clog filters and contaminate oil.
• Heavy use: If your equipment runs all day every day, oil breaks down quicker. Continuous operation puts constant stress on the oil and makes it work harder.
• Extreme temperatures: Very hot or very cold weather can affect how well oil does its job. In cold climates, oil thickens and flows slower. In hot climates, it thins out faster and breaks down more quickly.
• Towing or pulling heavy loads: Putting extra strain on your engine means the oil works harder and degrades faster. Equipment used for heavy demolition or material handling needs more frequent oil changes.
• Older equipment: Machines with more wear may benefit from more frequent oil changes. Older engines often have more internal wear, and fresh oil helps protect them better.
• Idling for long periods: Equipment that sits running without doing work can accumulate moisture and contaminants in the oil over time.

If you operate in tough conditions, talk to your dealer about whether you should shorten your oil change interval. They know the local conditions and can recommend what works best for your area and type of work.

Checking Your Oil Between Changes

You don't have to wait until your scheduled oil change to check on your oil. Regular checks help you spot problems early before they become expensive repairs. This simple habit takes just a few minutes and can save you thousands in repair costs.

Here's how to check your oil:

1. Park your equipment on level ground and let the engine cool for a few minutes.
2. Locate the dipstick (your manual will show you where).
3. Pull it out and wipe it clean with a rag or paper towel.
4. Push it back in all the way, then pull it out again to get an accurate reading.
5. The oil level should be between the minimum and maximum marks on the stick.
6. Look at the oil color—it should be brown or black. If it looks milky or has a burnt smell, something may be wrong.
7. Check for any debris or metal particles in the oil, which could signal engine problems.

If your oil level is low, add the correct type of oil recommended in your manual. Never mix different oil types or grades. If you notice unusual colors, smells, or particles, have a mechanic look at it right away. These signs can mean something is wrong inside the engine that needs attention.

What to Do During an Oil Change

When it's time for an oil change, you'll need to complete several steps to do the job properly. Whether you do this work yourself or have a professional handle it, understanding the process helps you know what's involved and why it matters.

• Drain the old oil into a container (make sure the engine is warm so oil flows freely)
• Replace the oil filter with a new one of the correct type
• Add new oil to the correct level using the type specified in your manual
• Check the level again with the dipstick to make sure it's right
• Dispose of the old oil properly (many recycling centers take used oil for free)
• Record the date and hour meter reading in your maintenance log

If you're not comfortable doing this yourself, your dealer or a may have access to mechanic can handle it. The cost is usually worth it to make sure it's done right. A professional will also inspect other parts of your equipment while they're servicing it, which can catch problems early.

Keeping Track of Your Oil Changes

It's easy to forget when you last changed the oil, especially if you run multiple pieces of equipment. Keeping good records helps you stay on schedule and avoid missing important maintenance. A simple system is one of the best tools you can use to protect your investment.

Some operators mark the date on the oil filter itself as a quick reminder. Others use a maintenance notebook or spreadsheet. Many modern equipment owners use phone apps or digital logs to track service. Pick whatever system works for your operation. The important thing is that you have a way to know when service is due and what you've already done.

Your equipment's hour meter is the most reliable way to track when an oil change is due. Write down the hour meter reading each time you service your machine, and you'll always know how many hours until the next change is needed.

Frequently Asked Questions

What happens if I don't change my oil on schedule?

Skipping oil changes causes oil to break down and become contaminated. Dirty oil can't protect your engine properly, leading to increased friction, heat, and wear on engine parts. Over time, this causes serious damage like bearing wear, piston scoring, and valve problems. These repairs are expensive and can put your equipment out of service for weeks. Regular oil changes cost far less than the repairs you'll face if you neglect maintenance.

Can I use the same oil in my skid steer and excavator?

Not always. Different machines may require different oil grades and types. Always check your equipment manual for the specific oil recommendation for each machine. Using the wrong oil can damage your engine and void your warranty. Some equipment uses standard motor oil, while others require special hydraulic oil or synthetic blends. When in doubt, ask your dealer or equipment manufacturer which oil is right for your specific model.

How do I know if my oil filter needs replacing?

You should replace your oil filter every time you change the oil. The filter traps dirt and contaminants, and over time it becomes clogged and less effective. A clogged filter makes it harder for oil to flow through your engine, which can cause damage. Replacing the filter is inexpensive compared to engine repairs, so it's always worth doing. Most manufacturers recommend changing the filter at the same interval as the oil change.

Is synthetic oil better for construction equipment?

Synthetic oil lasts longer and performs better in extreme temperatures than conventional oil. However, it costs more, and not all equipment is designed for it. Check your manual to see if synthetic oil is recommended or approved for your machine. Some older equipment should only use conventional oil. If your equipment operates in very hot or very cold conditions, or runs continuously, synthetic oil may be worth the extra cost because it requires fewer changes and provides better protection.

What should I do if I find metal particles in my oil?

Metal particles in your oil can signal that something inside the engine is wearing out or damaged. Stop using the equipment and have a mechanic inspect it right away. Small amounts of wear are normal, but visible metal particles mean there's a problem that needs attention. Catching this early can prevent a complete engine failure that would cost thousands to repair.

The Bottom Line

Oil changes are a small investment that pay off big. Sticking to your manufacturer's schedule—and adjusting it for your working conditions—helps prevent breakdowns and keeps your skid steers and excavators ready to work. Clean oil means a happier engine and more time on the job instead of in the shop.

Make oil changes part of your regular maintenance routine, keep good records, and your equipment will reward you with years of reliable service. The few dollars you spend on oil and filters now will save you thousands in repair costs down the road.
