What Type Of Oil For A Lawn Mower?

When choosing what type of oil for your lawn mower, there are many things to consider. Lawn mower engine dependability is vital to running a profitable lawn care business, yet most small-engine oils we’ve tested are nothing more than re-labeled automotive oils, which are formulated with fuel economy in mind, not durability. That won’t cut it. Compared to liquid-cooled automotive engines, small engines in lawn mowers run hotter; operate under constant load; generate more oil-damaging contaminants; suffer from neglected maintenance; and are exposed to dirt, rain, snow, and other extremes. Simply put, lawn mower engines are far tougher on oil than most people think.

AMSOIL Synthetic Small-Engine Oil for lawn mowers isn’t merely a re-badged automotive oil. Instead, we designed it from the ground up specifically for small-engine dependability. You can rest assured the engines in your lawn mowers are protected even during periods of extended use when there’s no time for scheduled maintenance. It’s built to solve the problems that plague small engines, including wear, power loss, oil consumption, harmful carbon deposits, and stuck rings and valves. It helps landscapers, contractors and other professionals get more work done and save money.

Lawn Mower Oil Type Recommendations

AMSOIL Synthetic Small-Engine Oil is multifunctional and can be used in gasoline engines, off-road diesel engines, and certain transmissions. It doesn’t contain friction modifiers and meets JASO wet-clutch standards. It increases convenience and helps prevent misapplication. Use the appropriate viscosity of AMSOIL Synthetic Small-Engine Oil in applications that require any of the following specifications:

  • API SL, SJ, SH, SG (Gasoline)
  • API CD, CF (Diesel)
  • JASO MA/MA2 (Wet Clutch)

Use 5W-30 Synthetic Small-Engine Oil in small engines found in (not limited to) snow blowers, generators, power washers, and other equipment that requires SAE 30 or 5W-30 motor oil, including those made by Briggs & Stratton, Honda, Kohler, Champion, Generac, Toro, Ariens, Troy Bilt, John Deere, MTD, and Husqvarna.

Use 10W-30 Synthetic Small-Engine Oil in small engines found in (not limited to) mowers (zero-turn, riding, stand-on, push), generators, power washers, and other equipment that requires SAE 30 or 10W-30 motor oil, including those made by Briggs & Stratton, Honda, Kubota, Kawasaki, Kohler, Tecumseh, Robin, Onan, Wisconsin, Powertrain, Yanmar, Linamar and Vanguard.

Use 10W-40 Synthetic Small-Engine Oil in small engines found in (not limited to) mowers (zero-turn, riding, stand-on, push), generators, power washers, and other equipment that requires SAE 10W-40 or 15W-40 motor oil, including those made by Kubota, Kawasaki, Robin, Onan, Linamar and Vanguard.

Use 15W-50 Synthetic Small-Engine Oil in small engines found in (not limited to) mowers (zero-turn, riding, stand-on, push), generators, power washers, and other equipment that requires SAE 50, 10W-50, or 15W-50 motor oil.

Lawn Mower Oil Capacity

Walk-Behind Mower Oil Capacity:
Oil capacity for most walk-behind mowers is between 15oz – 18oz (check manufacturers owner manual for oil capacity) Use AMSOIL and change engine oil every 200 hours or annually, whichever comes first.

Riding Mower Oil Capacity:
Oil capacity for most riding mowers is between 48oz – 64 oz (check manufacturers owner manual for oil capacity) Use AMSOIL and change engine oil every 200 hours or annually, whichever comes first.

Is Synthetic Oil Better For Lawn Mowers?

Synthetic oil is better for lawn mowers than conventional oil Synthetic oils offer many advantages for your lawn mower: high lubricity, reduced wear and friction, improved fuel economy, and reduced emissions. Synthetic oil provides excellent protection against wear and corrosion. Protect your lawn mower’s engine oil with AMSOIL Synthetic Lawn Mower Oil to help keep it running smoothly for years to come.

How To Check Lawn Mower Oil?

  • Remove the dipstick cap, apply a little pressure, and twist counterclockwise.
  • Remove the dipstick and wipe with a clean rag to get an accurate reading.
  • Before reinstalling the dipstick, make sure the cap is lined up with the grooves on the dipstick tube.
  • Apply a little pressure and twist clockwise to reinstall the dipstick cap.
  • Remove the cap again and view the oil level towards the bottom of the dipstick.
  • The oil level should be between the full and add marks.
  • If the oil level is low, pour a few ounces at a time to avoid overfilling.
  • Allow enough time for the oil to settle before rechecking the oil level.

What Is The Best Synthetic Oil For Your Lawn Mower Engine?

AMSOIL Synthetic Small Engine Oil is the best synthetic oil to use in your lawn mower engine because of these reasons listed here:

Excellent Wear Protection

AMSOIL Synthetic Small-Engine Oil is a shear-stable, high-film-strength formulation fortified with a heavy dose of anti-wear additives. It does not thin out due to mechanical shear, ensuring a thick lubricating film. It forms a durable barrier that protects
against metal-to-metal contact.

Reduces Oil Consumption

In lab testing, AMSOIL 10W-30 Synthetic Small-Engine Oil reduced oil consumption by 61 percent compared to three leading 10W-30/SAE 30 motor oils.¹ Its heat-resistant synthetic base oils provide low volatility, excellent viscosity stability, and strong oxidation resistance. Engines run longer between top-offs, providing peace of mind they won’t fail due to oil starvation and will run dependably in the harshest conditions.

Formulated for Power

Engine wear, carbon deposits, valve sticking and piston-ring sticking reduce engine power. AMSOIL Synthetic Small-Engine Oil prevents ring and valve sticking while helping eliminate carbon deposits from forming. As a result, engines produce maximum power throughout their service lives, helping you get more work done.

Extreme-Temperature Performance

AMSOIL Synthetic Small-Engine Oil’s saturated molecular structure offers outstanding extreme-heat resistance. In addition, we’ve fortified the oil with potent anti-oxidant additives that provide further resistance to damaging heat. Its powerful detergent additives fight carbon, varnish, and sludge to maximize engine life. In extreme cold, the oil’s naturally high viscosity index and lack of paraffin (waxes) ensure it remains fluid and flows quickly, providing easier cold-weather starts and fast startup lubrication for reduced wear.

In conclusion, when determining why type of oil for a lawn mower, there are many different types of oil that can be used in a lawn mower. However, the best type of oil for a lawn mower is motor oil. Motor oil is specifically designed to lubricate the moving parts of an engine and it helps to protect the engine from wear and tear. It is important to use motor oil in a lawn mower because it will help to keep the engine running smoothly and it will extend the life of the lawn mower.
