How to Change the Oil on Your RV or Motorhome

Why Oil Changes Matter for Your RV

Regular oil changes are one of the most important maintenance tasks for keeping your RV or motorhome running smoothly. Oil keeps your engine lubricated, helps it run cooler, and removes dirt and debris that builds up over time. Without clean oil circulating through your engine, parts wear down faster and friction increases, which can lead to serious engine damage and expensive repairs.

Most RVs need an oil change every 3,000 to 5,000 miles, though some newer models may go longer between changes. The exact interval depends on your engine type, how you use your RV, and the climate where you travel. Check your owner's manual for the specific schedule recommended for your vehicle. Staying on top of oil changes is one of the best ways to keep your engine healthy and avoid breakdowns on the road.

What You'll Need

Before you start, gather all the supplies you'll need to complete the job. Having everything ready beforehand makes the process go faster and smoother. Here's a complete list of items to collect:

• New oil (the correct type and amount for your RV engine)
• A new oil filter
• An oil drain pan (at least 5 gallons capacity)
• A wrench or socket set that fits your drain plug
• An oil filter wrench
• Rags or paper towels for cleanup
• Jack and jack stands (if needed to access the drain plug)
• Safety glasses to protect your eyes
• Work gloves to keep your hands clean

The most important thing is getting the correct type and weight of oil for your RV's engine. Check your owner's manual to find this information—it's usually listed as something like "5W-30" or "10W-40." Using the wrong oil can cause poor engine performance and may damage your engine over time. If you're unsure, ask the staff at an auto parts store or consult your RV's manual.

Step 1: Warm Up Your Engine

Start your RV and let the engine run for a few minutes to warm up. Warm oil flows much better than cold oil and will drain more completely from your engine. This means you'll remove more of the old, dirty oil and get a better oil change overall. The warmth helps loosen the oil so it flows freely out of the drain pan.

Don't let the engine get too hot, though. You want it warm enough that you can't comfortably hold your hand on the engine block for more than a few seconds. If it gets too hot, you risk burning yourself when you work with the drain plug and filter. A good rule of thumb is to run the engine for about 3 to 5 minutes, then turn it off and wait another minute before you start draining.

Step 2: Locate and Access the Drain Plug

Turn off the engine and let it cool for just a minute or two. Then locate the oil drain plug underneath your RV's engine. On most motorhomes, you'll find it on the bottom of the engine block. You may need to raise your RV with a jack or crawl underneath to reach it comfortably. Before you get under your RV, make sure it's parked on level ground and that the vehicle is stable and secure.

If you need to raise your RV, use a proper jack and always support it with jack stands. Never work under a vehicle that's only supported by a jack—jack stands are essential for safety. Once you can access the drain plug, position your drain pan directly underneath it to catch the old oil. A drain pan is important because old oil can be messy and you need to dispose of it properly later.

Step 3: Drain the Old Oil

Use your wrench to loosen the drain plug by turning it counterclockwise. Once it's loose enough to turn by hand, carefully unscrew it the rest of the way. Be careful at this point—the oil may still be warm or even hot, so move slowly and watch out for drips. Once the plug is out, let the old oil drain completely into the pan. This process usually takes 5 to 10 minutes, depending on how much oil is in your engine and how warm it is.

While you're waiting for the oil to drain, you can use this time to locate your oil filter and gather your other supplies. Once the dripping slows to just a few drops, the oil has drained enough. Take a clean rag and wipe the drain plug clean, removing any dirt or old oil residue. This helps you see if the plug is in good condition and makes it easier to reinstall.

Step 4: Replace the Drain Plug

Screw the drain plug back into the hole by hand first. This prevents you from cross-threading it, which can damage the threads and cause leaks. Once the plug is hand-tight, use your wrench to tighten it a bit more. The goal is to make it snug and secure, but not overly tight.

Over-tightening the drain plug is a common mistake that can cause problems. If you tighten it too much, you can crack the plug or strip the threads in the engine block, both of which can lead to oil leaks. A good approach is to tighten it until you feel resistance, then give it just a quarter turn more. This creates a good seal without damaging anything.

Step 5: Change the Oil Filter

Now it's time to replace the oil filter. Locate the oil filter, which is usually a cylindrical canister mounted on the side of the engine. Before you remove it, position your drain pan underneath it because there will be some oil inside the filter that will spill out when you remove it.

Use an oil filter wrench to loosen the filter by turning it counterclockwise. Once it's loose enough, carefully unscrew it by hand and set it aside. Be prepared for some oil to drip out—this is normal. Before you install the new filter, apply a thin layer of new oil to the rubber gasket, which is the ring-shaped seal on the top of the filter. This thin coating helps create a good seal between the filter and the engine, which prevents leaks.

Screw the new filter onto the engine by hand until the gasket touches the engine surface. At that point, turn the filter an additional three-quarters of a turn to tighten it. This is the proper amount—not too loose and not too tight. Never use the oil filter wrench to tighten the new filter, as this can over-tighten it and cause damage.

Step 6: Add New Oil

Locate your oil filler cap on top of the engine and remove it. This is where you'll pour in the new oil. Pour in the amount of new oil recommended in your owner's manual, but start with a little less than the full amount recommended. This gives you room to check the level and add more if needed without overfilling.

Replace the oil filler cap and wait about a minute for the oil to settle and flow down into the engine. Then use the dipstick to check the oil level. Pull the stick out, wipe it clean with a rag, reinsert it fully, and pull it out again to get an accurate reading. Add more oil in small amounts until the level reaches the full mark on the dipstick. Don't overfill your engine, as too much oil can cause problems.

Step 7: Start Your Engine and Check for Leaks

Start your RV and let the engine run for about a minute. During this time, watch carefully around the drain plug and the oil filter for any leaks. The new filter and drain plug should seal properly and not drip. If you see any leaks, turn off the engine and tighten the drain plug or filter a bit more.

After the engine has run for a minute, turn it off and wait a few minutes for the oil to settle. Then check the oil level again using the dipstick and top it off if needed. It's normal for the level to drop slightly after the first run because the new filter fills with oil. Once everything looks good and there are no leaks, your oil change is complete.

Dispose of Old Oil Properly

Never pour old oil down the drain, into the ground, or into a storm drain. Used motor oil is harmful to the environment and can contaminate groundwater and soil. Proper disposal is both an environmental responsibility and often a legal requirement.

Take your old oil to a local recycling center, auto parts store, or service station. Many of these places will take used oil for free, and some may even give you a small discount on new oil. Call ahead if you're unsure whether a particular location accepts used oil. Some RV parks and campgrounds also have oil disposal facilities available for guests.

Keep Records of Your Oil Changes

Write down the date, your RV's mileage, the type of oil you used, and the capacity of your engine. Keeping a maintenance log helps you remember when your next oil change is due and ensures you don't miss scheduled maintenance. This record is also valuable if you ever decide to sell your RV, as it shows potential buyers that your vehicle has been well-maintained.

You can keep records in a notebook, a folder in your RV, or even on your phone. Some RV owners take photos of their maintenance receipts and store them digitally. Whatever method works best for you, the important thing is staying consistent and keeping track of your maintenance history.
