Best Oil for Lawn Mower – By Experts

Hello guys, welcome back to another episode of Mackaliesgarden.

We have a lot of queries about the best lawn mower oil for your lawn mower. Maintaining your lawn mower is essential in ensuring you get the best performance. One of the critical components of lawn mower maintenance is changing the oil regularly.

In this article, we will discuss the best oil for lawnmowers and its types. We will also tell you about the benefits of using different kinds of oil on a lawn mower engine. So let’s start without further ado!

Choosing Lawn Mower Oil By Engine Type

For a 4-cycle engine, adding oil is distinct from that for a 2-cycle engine. Lawnmowers with 4-cycle engines have separate fuel and oil tanks which must be filled separately. The most common oil used in lawnmowers is 30 wt oil for lawn mower, the same as in many cars. This weight designates the oil’s viscosity or thickness. When selecting a lawn mower oil, you have three options:

  • Synthetic blend
  • Synthetic,
  • conventional motor oils.

Lawn Mower Oil Types: Pros and Cons

Oil is essential for keeping your lawn mower running smoothly. Briggs and Stratton, a leading producer of small engine equipment, recommends using high-quality detergent oil classified as “For Service, SG, SF,SH, SJ” or higher.” 1

When shopping for oil for your lawn mower, avoid special additives and check the label to determine if the oil is synthetic or conventional. The American Petroleum Institute (API) has established an oil classification system, with SF through SJ designated for automobiles. However, these classifications also cover a wide range of applications for lawnmowers.

Therefore, when selecting oil for your lawn mower, it is essential to check that it meets the appropriate classification. This will ensure your lawn mower runs efficiently and reliably. High-quality oil in your lawn mower can extend its lifespan and provide a healthier, greener lawn for years.      

Conventional Oil

Conventional oils are mineral-based products created from crude oil. They are refined to remove impurities and contain additives to help protect engines against wear, rust, and heat. Conventional oils typically cost less than synthetic oil but offer less protection than synthetics.

Synthetic Oil

Synthetic oil is a lab-created oil made of base stocks chemically engineered to provide superior protection for your lawn mower. It is more costly than conventional oil but can last longer, offer better protection from temperature extremes, and improve lubrication performance. Synthetic oils may also require fewer changes throughout the season.

Synthetic Blends Oil

Synthetic blends are a combination of conventional and synthetic oil that offer the performance benefits of both. Synthetic blend oils are generally more affordable than pure synthetics but require more frequent changes than full-synthetic options.

The difference between fully synthetic and synthetic blends is a matter of quality. Synthetic oil is more durable, offers better protection, and lasts longer than conventional oil. Synthetic blends are cheaper and may provide some of the synthetic oil’s benefits but will require more frequent changes. 

Lawn Mower Oil: Climate Factors

Manufacturers have claimed that synthetic oils break down more slowly than conventional oils, but following the timetable given in the owner’s manual is crucial regardless of the breakdown rate.

However, checking the oil level before every mow is equally essential as lawnmowers are designed to work hard, and it takes just one instance of neglecting to add oil when it’s low to cause significant damage. Another factor to think about when choosing the best oil is the temperature. Learning which oil suits your climate is essential to ensure your lawn mower runs smoothly, resulting in a healthier, more beautiful lawn for longer.

The oil you should use in your mower depends on the climate. Here are some different grades of oil to consider:

  • SAE 30: Warmer temperatures, typically used for smaller engines
  • SAE 10W-30: Variable temperature range, this grade of oil promotes easier starting when it’s cold but can lead to an increase in oil consumption
  • Synthetic SAE 5W-30: Gives the best protection at all temperatures and improves starting without increasing oil consumption. Try top-rated Castrol Edge 5W-30 Full Synthetic Motor Oil. Try top-rated Castrol Edge 5W-30 Full Synthetic Motor Oil.
  • SAE 5W-30: Frigid temperatures
  • Vanguard 15W-50: Varying temperature range, this grade of oil is ideal for continuous use, such as commercial lawn cutting or pressure washing. Try top-rated Mobil 1 Advanced Full Synthetic 15W-50 Motor Oil.

Lawn mower oil capacity

Walk-behind mowers: 

  • In walk-behind mowers, Oil capacity is typically 15 or 18oz*.
  • Periodically Check oil level during the season and add when necessary
  • Periodically Change engine oil every 50 hr or yearly, whichever comes first.

Riding mowers:

  • Oil capacity is generally 48oz or 64 oz*.
  • Change engine oil every 100 hours or yearly, whichever comes first.

How do you check the oil level before the use of the mower?

Items you may need to change the oil:

  • A pan or container to catch the old oil. 
  • some old rags or cloths 
  • A wrench with appropriate socket size for the oil drain nu 
  • Engine oil that suits your needs 
  • Funnel 
  • Siphon or oil kit system if you are going to siphon rather than drain

Changing of oil

  1. Locate your vehicle on a level surface and remove the dipstick cap.
  2. Pull out the dipstick, wiping away debris with a clean cloth to get an accurate reading.
  3. Replace the cap accurately by ensuring that its teeth fit into the groove of the dipstick tube.
  4. Remove the cap again and check the oil level near the bottom of the dipstick blade.
  5. The oil should reach the full and add marks indicated on the dipstick.
  6. If the level is low, gradually pour a few ounces of oil at a time to avoid overfilling.
  7. Enable enough time for the oil to settle before rechecking its level.

Key Takeaways

  • There are two main types of lawnmowers- 2-stroke and 4-stroke ones. 
  • SAE 30 is the best type of oil for 2-stroke engines or older/ smaller engines. 
  • 4-stroke lawn mowers can run with SAE 10W-30, SAE 5W-30, or Synthetic SAE 5W-30. But the oil type depends on climate, usage, and engine models. 
  •  Briggs & Stratton SAE 5W-30 is the best lawn mower oil for colder climates. 
  • You should change your lawnmower oil after every 50 hours of operation.

FAQ About Lawn Mower Oil

What type of oil do you use in a lawn mower?

There are a few factors to consider. The engine type, operating temperatures, and manufacturer recommendations can all influence the type of oil you should use. A mix of oil and fuel is typically recommended for two-stroke engines, while four-stroke engines usually call for straight oil. The specific grade of oil you choose may also depend on the operating temperatures in your area. By considering these factors and following the manufacturer’s guidelines, you can ensure that your lawn mower stays in tip-top shape for years.

Can we use regular motor oil in a lawnmower?

Yes, you can use regular motor oil in lawn mower engines. However, ensuring the oil is specifically designed for use in small gasoline engines is essential. Most two-stroke engine manufacturers recommend synthetic or semi-synthetic oils because they offer better protection against wear and tear and improved fuel efficiency.

What’s the ideal oil to use in a lawn mower?

The best oil for your lawnmower will depend on the engine type, operating temperatures, and manufacturer recommendations. For two-stroke engines, it’s generally recommended to use synthetic or semi-synthetic oil. A lubricant specifically designed for small gasoline engines is best if you have a four-stroke machine.

Can I use 10W30 instead of SAE30 in My lawnmower?

No, 10W30 is not recommended for lawnmower use because it has different viscosity and additives than SAE 30. Use the grade of oil your manufacturer recommends to ensure optimal performance and extended engine life.
