Types Of Oil For Lawn Mower

How to Change Oil in Lawn Mower

As we have mentioned, there are different types of lawn mowers that require different types of engine oil. Some people also use motor oils for this purpose, which work in a similar fashion. These motor engine oils are designed to work in smaller engines as well, so you can use them too. But we would suggest that you use those motor oils only when you dont have access to dedicated mower oils.You need to make the right choice based on the climate in which you live. We have listed some of the most frequently-used types of oil from different regions and continents.

Lawn Mower Oil Type Recommendations

Different oil types can work best at certain temperatures. Learn which one to choose for your climate.

  • SAE 30– Warmer temperatures, most common oil for small engines.
  • SAE 10W-30– Varying temperature range, this grade of oil improves cold-weather starting, but may increase oil consumption.
  • Synthetic SAE 5W-30– Best protection at all temperatures as well as improved starting with less oil consumption.
  • SAE 5W-30– Very cold temperatures.
  • Vanguard 15W-50– Varying temperature range. For continuous-use, such as commercial lawn cutting or pressure washing.

When choosing lawn mower oil, use a high-quality detergent oil classified as “For Service SF, SG, SH, SJ” or higher. Do not use special additives.

Synthetic oils are an acceptable oil at all temperatures. The use of synthetic oil does not alter required oil change intervals.

Purchase the right oil for your engine at

*Below 40°F the use of SAE 30 will result in hard starting. **Above 80°F the use of 10W30 may cause increased oil consumption. Check oil level more frequently.

  • Oil capacity is typically 15oz or 18oz*.
  • Change engine oil every 50 hours or annually, which ever comes first.

Riding mowers:

  • Oil capacity is typically 48oz or 64 oz*.
  • Change engine oil every 100 hours or annually, which ever comes first.

*Do not over fill your engine with oil. Use the Oil Finder tool above or check your operator’s manual for the proper amount of oil recommended for your engine.

Why Do Lawn Mowers Need Oil

Lawnmowers, like other garden hand tools, garden tractors also require oil to function properly. This is due to the fact that oil lubricates the multiple aspects of the engine. As a result, friction and general wear and tear are reduced. Not all lawn mowers, however, utilize the same engine oil. This is due to the fact that each oil has a variable fluidity, or how rapidly it flows under different conditions. Most basic engines include several moving components, which are often built to operate at high speeds and temperatures. Thats why oils lubricating and cooling qualities are so important. Your lawn mowers motor would soon overheat, stop, and be damaged if it didnt have it.

How Is Synthetic Oil Different From Mineral Oil

Synthetic oil has several advantages over mineral oil. According to Consumer Reports, synthetics:

  • Resist oil breakdown, which means you do not have to change it as often.
  • Withstands higher temperatures, important in four-stroke engines.
  • Flows better at cold temperatures.
  • Contain the precise molecules the engine needs for a specific application.
  • Less likely to acidify and oxidize.
  • Combats sludge and deposit buildup.
  • Offers greater engine wear protection.
  • Keeps your engine cleaner.
  • Keeps turbochargers working better and protects them more.
  • Protects the engine from strain during heavy hauling and temperature extremes.

What Is Synthetic Oil And Should I Use It In My Lawn Mower

Synthetic oil is superior to lubricants made from crude oil, and your lawn mower engine may last longer if you use synthetic. It is an artificially created lubricant with a mix of chemical compounds designed to get the best performance and protection for the engines they are used in that the natural oil may not be able to provide.

According to Briggs and Stratton, one of the worlds largest manufacturers of small engines, the use of synthetic oil does not alter required oil change intervals. Regular, non-synthetic oil works well, too. Ive used non-synthetic in some of my small engines for 30 years, and these motors still start and run as if they were new.

Warm Oil & Prepare Work Surface

Start the engine and let it run for 2 to 3 minutes to warm the oil and shut off the engine. Warm oil will flow better than cool oil. Just be careful when working around the hot engine so you dont burn yourself.

While you let the engine warm, you can cover the work surface with cardboard to keep spilled oil from soaking into your solid surface. Park the mower on top of the cardboard.

Maintenance Schedule & Approximate Capacity:

  • Oil capacity is typically 15oz or 18oz*.
  • Change engine oil every 50 hours or annually, which ever comes first.

Riding mowers:

  • Oil capacity is typically 48oz or 64 oz*.
  • Change engine oil every 100 hours or annually, which ever comes first.

*Do not over fill your engine with oil. Use the Oil Finder tool above or check youro perators manual for the proper amount of oil recommended for your engine.

How Do You Drain Overfilled Oil

Because of the significant engine damage that can occur from overfilling your engine, you need to remove oil if you are above the manufacturers recommended engine oil level. There are several different methods you can use to remove oil.

For safety reasons, remove the key and remove the spark plug wire so your engine does not start while you are working on your lawn mower.

Drain Plug or Valve Port: You need to find the drain plug or valve port on the engine if your lawn mower has one. It may be found on the side of the engine by the dipstick or at the bottom of the oil pan under the lawn mower. Have your drain pan ready to collect the oil. Remove the plug for a quick second and replace. Check your oil level. Repeat if necessary.

Oil Filter: If your engine uses an oil filter, you can drain a little oil by loosening or removing the oil filter. You will need to have a rag handy to collect the oil.

Fill Hole: Your mower may not have a drain plug or oil filter. Many small engines on push mowers do not have a drain plug and you must tip the mower over to drain a little oil out of the fill hole. Remember to keep the carburetor on the high side when tipping the mower so oil doesnt run into the carburetor or air filter.

Oil Extractor Pump: An oil evacuator works well to remove oil. An extractor will remove oil through a tube inserted into the engine oil fill hole.

What Kind Of Oil Does A Lawn Mower Take

  • Lawnmower engine oil is vital to lawnmower performance. Filling the engine with the right oil is essential for smooth operation. The choice of lawnmower oil is determined by the lawnmower size, the climate of the area you live in, and whether the mower is for commercial use or residential use.

    Different types of oils are recommended for varied temperature ranges. SA30 is suitable for small engines in warm temperatures, while SAE10W-30, SAE 10W-30, and SAE 5W-30 are multigrade oils perfect for varying temperatures. Synthetic and synthetic blend oils are better performing graded oils options.
