How To Choose The Best Lawn Mower Oil?


Apart from ensuring that the blade is sharp, you should change the oil regularly. If you have checked online stores, there are hundreds of oil brands, some from known companies, and others from generic brands. When buying oil, consider these two factors.Choose The Best Lawn Mower Oil

Synthetic or regular oil

While most lawn mowers can use any oil from stores, synthetic oil is superior. The synthetic oil, for example, is more refined and, therefore, better for moving parts. With fewer impurities, you are guaranteed more time before changing the oil. Thus, in the long last, synthetic oil brands are economical.

On the other hand, regular oil brands are cheaper, and you can get them anywhere, even in your nearest store. While most lawn mowers will work effectively with these oil brands, you will need to change the oil more often than in the other case.

Buy oil from a renowned brand.

In the past five years, the market for lawn mower oils has seen a saturation of brands. The brands are not only more refined but also competitive regarding pricing. While this growth is a blessing to millions of homeowners, it may pose a challenge to some homeowners.

Therefore, you should consider oil brands from known companies. In this case, an ideal oil brand should have a history of good products and, more importantly, pure oils.

If you are uncertain about the oil brands, check the ten products highlighted above. The ten products are not only well priced but also tested for lawnmowers.

What Kind Of Oil For A Lawnmower?


While any lawn mower can technically use any oil, not all types of oils are ideal for your machine. Therefore, you should know the following things when buying oil for your lawnmower.

Viscosity grades

The main difference between oils is viscosity grades. Currently, there are five different oil grades based on viscosity. They include:

  • Synthetic SAE 5W-30 – If you are looking for the best oil grade in terms of viscosity, the Synthetic SAE 5W-30- is the best option. Also, the oil grade has better oil consumption, regardless of the engine size.
  • SAE 30 – The oil grade is ideal for small machines and, more importantly, lawnmowers working in hotter spaces. However, the oil grade is not suitable for bigger and more powerful engines.
  • SAE 10W-30 – This viscosity grade improves SAE 30 but with less efficiency in oil consumption. Also, the oils under this grade work well in colder places.
  • Vanguard 15W-50 – This oil grade is for commercial machines regardless of the lawn mower’s size. Also, the oil brand is unmatched because of its high shear rate.

Oil capacity

Apart from viscosity grades, you should consider the engine’s oil capacity before buying any oil brand. In this case, the oil brands are divided into two:

Oil capacity for riding mowers

If you have a riding mower, you should buy oil between 48oz and 64 oz. You should also change the oil after 100 hours and if you rarely use it, at least once in a year.

Oil capacity for walk-behind mowers

On the other hand, you should buy oil brands with 15oz and 18oz if you have a walk-behind mower. Also, you should change the oil every year or if you use the lawnmower for 50 hours.

Is Synthetic Oil Good For Lawn Mower Engines?


Yes. The manufacturing process of synthetic oil is different from other regular oil options in the market. The refining process, for example, is longer and controlled compared to traditional refining processes. In the end, the oil is pure and has fewer chemical impurities.

Due to the refining process, the lawn mower’s parts will move effectively with less friction and the need to change oil regularity. Also, the synthetic oil brands minimize the impurities in your engine and therefore reduce mechanical problems.

When moving from regular oil brands to synthetic brands, you should consider some factors. First, the prices are relatively higher compared to standard oils. If you are on a tight budget, the transition to synthetic oil is not an idea.

Second, many regular oil brands have fewer impurities and are ideal for lawn mower’s engine. Consequently, it would be best to look for a professional opinion in your locality before making the final decision.

 

Can You Use Car Oil For A Lawnmower?


Yes. The car and lawn mower’s engine has many similarities. Therefore, you can use a car’s oil for your lawnmower. However, there are different possible outcomes if you use the car oil on your lawn mower. The possibilities include:

First, car oils are now better than before, and you will get value for money. Unlike some regular oil brands, they are refined and have fewer impurities. However, they are more expensive than ordinary oils.

The second possibility is that the car oil may not be of the same velocity as the regular lawn mower’s oil brands. Therefore, the difference will affect engine functionality in the long run.

Based on the two possibilities, it is correct to state that using the correct lawn mower’s oil is the best bet for your machine. Also, using any of the above oils eliminates the need to have a professional assess the engine’s state after some time.

How To Change A Lawn Mower Oil Filter? 


While most lawn mowers do not have oil filters, the newer models come with filters. If your engine does not have a filter, skip this part. On the other hand, if your lawnmower has an oil filter, follow these steps.

Prepare to catch the oil and avoid spilling inside the engine.

The preparation is the first and one of the critical steps you should not skip. Find something to catch the old oil in the lawnmower and put it under the filter as you unscrew it.

Prepare the new filter by applying oil around it.

One of the major challenges you are more likely to face is the new filter, not fitting. However, applying oil around it ensures that it seals tightly and therefore avoiding future problems.

Screw the filter

Once you have applied oil around the new filter, the next step is to fit it in your lawnmower. When screwing the new filter, make sure the screws are tight without applying too much force.

 

Final Recommendation


Based on the above reviews, it is clear that there are many good brands in the market. Regardless of your budget, you can get a good oil brand. Also, the reviews above consider pricing and the frequency of changing oil as key factors.

Contrary to marketing narratives, you can use different oil brands without affecting your engine. However, the oils must have fewer impurities. Also, other brands use a similar purification process but with varying results of purity.

Fortunately, the ten oil brands reviewed above are perfect for all lawn mowers because of three reasons. First, the oil brands have higher purity percentages compared to most options. Therefore, you are guaranteed of fewer impurities to your engine.

Second, the pricing is unmatched; even in oils from more prominent brands, the price is well-thought. Therefore, all the above ten brands are worth checking.  Finally, the oil brands reviewed above are perfect for both smaller and bigger engines.
