It’s true that, in recent years, lawn mowers have continued to get more and more sophisticated, with the potential of what they can do increasing exponentially in such a small period of time.
With push mowers, ride-on models, and everything in between, the market is full of great products and essential pieces of labor saving equipment.
However, these products still need their essential maintenance and upkeep, and without putting in the time, they can soon break down, become damaged, or decline in quality level.
One example is oil levels, and making sure it has enough to operate fully.
But how much oil should you put in a lawn mower, and what are the consequences of making mistakes?
How Much Oil Do Lawn Mowers Need?
While variations can occur regarding makes and models of lawn mowers, generally speaking, the following types of machines require the following amounts of oil:
- Push-reel mowers – no oil, as they do not have an engine.
- Self-propelled gas models – roughly 20 ounces/1.25 pints of oil.
- Gas-powered riding mowers – roughly 64 ounces/4 pints of oil.
- 4-cycle engines in sit-on mower tractors – roughly 48 to 64 ounces/3 to 4 pints of oil.
These are obviously generalizations, and changes could occur depending on the model and brand, however roughly speaking these are the amounts that all of these different mower types require to function at their highest level.
What Type Of Oil Do Lawn Mowers Require?
When it comes to choosing the right kind of oil for your lawn mower, this is also something that can change depending on the make and model. There are also different grades of oil, each having their suitability and advantages.
However, the manual for your lawn mower will instruct you on the kind of oil that would best suit the engine size and type of mower that you have, so with a little reading up on the matter the decision should become clear.
That being said, it is still worth reading up on the varieties that are available!
Single Grade Oil
This is the most basic kind of oil, and generally doesn’t have any additives. This means that the viscosity of the oil remains the same, and represents only at higher temperatures of around 100 degrees C.
Multi-grade oils are designed to provide differing levels of viscosity at different temperatures, meaning that it is designed to handle the changes in temperature that a lawn mower experiences, adapting accordingly.
Synthetic Blend Oil
This is a mixture of natural and synthetic oil that has been combined with additives that allow it to cope better at lower temperatures. These have all the benefits of synthetic oil, but without the cost.
These are artificial lubricants that are designed for high performance use, as well as commercial engines. These can generally be more expensive, but offer the most versatility and benefits across a number of different areas.
What Types Of Oil Are The Best?
Generally speaking, there are four main types of commercial oil that are commonly purchased on the market.
- SAE 30 Oil – good for warm temperatures and weather conditions
- SAE 5w-30 Synthetic Oil – good for warm and cold temperatures
- 10w-30 Synthetic Oil – suited for colder weather conditions
- 15w-30 synthetic oil – suited to high performance engines
This means that when it comes to choosing the right oil, it is important to assess your circumstances, and figure out what environmental conditions your lawn mower will come up against.
How Does Temperature Affect Oil?
Oil is a remarkable substance, and has a very intense relationship with heat – something that can be both a positive and negative when it comes to its usefulness.
Generally speaking, the temperature that oil is exposed to affects the viscosity of the oil, which in turn can have an impact on how well an engine runs, as well as the potential for problems to arise over time.
What Is Oil Viscosity?
Viscosity refers to the thickness of the oil, and finding the right balance is essential for engine lubrication.
Extremely cold weather conditions can make oil congeal – that is, become less runny and more like a gel – whereas hotter conditions can make it thinner, more runny, and generally insufficient when it comes to limiting metal to metal contact and providing proper lubrication.
The latter can result in grinding and damage to the inner workings of the engine, and the former can result in clogs, blockages, and improper lubrication as well.
This is why people generally have lightweight oils in periods of cold weather, and heavyweight oils in hot weather.
Synthetic Oil VS Crude Oil
People hear the word ‘synthetic’ and they assume inferior quality, however in the case of oil it is far superior to standard oil, and could have many benefits for your lawn mower in the long run.
The main benefit of synthetic lubricants is that they do not clog the engine, of course build ups as much as oil does, and the use of synthetic oil has actually been shown to grant the lawn mower in question a much longer lifespan than those that use crude oil.
And there we have it, everything you need to know about lawn mowers, and how much oil you should put in them to keep them operating at top capacity.
It’s true that lawn mowers have become more and more sophisticated in recent years, and the extent of what they can achieve is becoming more and more profound.
However, it just goes to show that, without the proper care, attention, and essential maintenance, they simply will not meet their potential.
So if you want to know how much oil to put in your lawn mower, then be sure to refer to this handy guide. Something tells me you won’t regret it!
