The warm weather is finally here, and it’s time to get your lawn in tip-top shape. But before you can mow, you need to make sure your Murray lawnmower is properly maintained. One of the most important maintenance tasks is checking and changing the oil.
Knowing how much oil your mower needs is crucial to prevent damage and ensure smooth operation. This article will walk you through everything you need to know about oil capacity in Murray lawnmowers, including how to find the right type of oil and how to change it properly. Let’s get started!
Short Answer: The amount of oil your Murray lawnmower takes varies depending on the model and engine size. You can usually find the specific oil capacity information in your owner’s manual or on a sticker located on the mower itself.
Finding Your Murray Lawn Mower’s Oil Capacity
The most reliable way to determine how much oil your Murray lawn mower needs is to consult the owner’s manual. This document will provide the exact oil capacity for your specific model.
If you don’t have your owner’s manual:
- Check the mower’s frame or engine: Look for a sticker or label that might indicate the oil capacity.
- Contact Murray customer service: They can provide you with the information you need based on your mower’s model number. You can find this number on a sticker on the mower or in the engine compartment.
- Search online: Using your model number, search online for your specific Murray lawn mower manual.
Understanding Oil Capacity Variations
The amount of oil a lawnmower requires can differ based on the size and type of engine. Generally, smaller engines in push mowers will have smaller oil capacities than larger engines in riding mowers.
Here are some examples of common oil capacities in Murray lawnmowers:
- Push Mowers (Single-Cylinder Engines): Often require 16 to 20 ounces of oil.
- Riding Mowers (Larger Engines): May require 24 to 32 ounces of oil, or even more for larger models.
Choosing the Right Oil for Your Murray Lawn Mower
Just as important as knowing the oil capacity is understanding the type of oil your mower requires.
Here’s what you need to know:
- SAE 30 or 5W-30 Oil: Most Murray lawnmowers use standard 30-weight oil, either SAE 30 for warm weather or 5W-30 for colder temperatures. Always refer to your owner’s manual for the specific recommendation.
- Synthetic or Conventional Oil: Synthetic oil offers better performance and longer lifespan, but it’s also more expensive. Conventional oil is a more budget-friendly option.
- Avoid Automotive Oil: Do not use car engine oil in your lawnmower. It’s designed for different operating conditions and can harm your mower’s engine.

Frequently Asked Questions
Here are 7 FAQs with answers about Murray lawn mower oil capacity:
1. How much oil does a Murray lawn mower typically hold?
The oil capacity of a Murray lawn mower can vary depending on the engine size and model. However, most Murray lawn mowers with small engines, like those found in push mowers, typically hold between 16 and 20 ounces of oil. For larger engines, such as those found in riding mowers, the capacity can be higher, ranging from 24 to 32 ounces.
It’s essential to refer to your owner’s manual for the exact oil capacity of your specific Murray lawn mower model. This will ensure you add the correct amount of oil and avoid overfilling or underfilling the engine.
2. What type of oil should I use in my Murray lawn mower?
Murray recommends using a high-quality, 4-stroke engine oil that meets the API service classification SJ or higher. For optimal performance and engine protection, choose an oil with a viscosity rating of SAE 30 for warmer temperatures or SAE 10W-30 for colder temperatures.
You can also consult your owner’s manual for the specific oil recommendations for your Murray lawn mower model. Avoid using oil designed for 2-stroke engines, as it’s not compatible with 4-stroke engines and can damage the engine.
3. How often should I change the oil in my Murray lawn mower?
It’s recommended to change the oil in your Murray lawn mower every 25 hours of operation or at the beginning of each mowing season. This helps to prevent engine wear and tear, prolong the life of your lawn mower, and ensure optimal performance.
For a lawn mower that’s used frequently, it’s best to check the oil level more often and change it earlier than recommended. If you notice any signs of contamination, such as excessive dirt or sludge, change the oil sooner to avoid engine damage.
4. Where is the dipstick located on my Murray lawn mower?
The oil dipstick is typically located on the side of the engine, near the oil fill cap. It’s often a metal rod with a handle that can be pulled out, wiped clean, and reinserted to check the oil level.
If you can’t find the dipstick, refer to your owner’s manual for its location. The manual will provide a detailed illustration of your lawn mower’s engine, including the dipstick position.
5. What if I accidentally overfill the oil in my Murray lawn mower?
If you overfill the oil, it can cause problems with the engine’s performance. Excess oil can be forced into the combustion chamber, leading to smoking and engine damage.
To remedy this situation, you’ll need to drain some of the excess oil. Use a siphon pump or a syringe to remove the excess oil until the level reaches the appropriate mark on the dipstick.
6. What happens if I underfill the oil in my Murray lawn mower?
Underfilling the oil can lead to engine damage, as the lack of lubrication can cause friction and wear on moving parts. This can result in overheating, engine seizing, and ultimately, costly repairs.
If you suspect you have underfilled the oil, immediately add the correct amount of oil. Regularly check the oil level and top it up if necessary. Avoid running the engine for extended periods without sufficient oil.
7. Where can I find more information about oil maintenance for my Murray lawn mower?
The most comprehensive information about oil maintenance for your Murray lawn mower can be found in your owner’s manual. It will provide detailed instructions on oil type, capacity, change intervals, and troubleshooting tips.
If you have lost your owner’s manual, you can find digital copies online on the Murray website or other reputable sources. You can also reach out to Murray customer service for additional support and guidance.
