What Type Of Oil Should I Use In My Mower

Lawn Mower Oil Guide: What Type of Lawn Mower Oil Should I Use? | eReplacementParts.com

Oil is incredibly important to keep your engine lubed up and running. Particularly in two-stroke mower engines, where oil and fuel are combined, having the right oil can mean the difference between getting your lawn mowed or having to take your mower in for repairs. So what oils are recommended for use in lawn mowers, and why?

How Often To Check And Change Lawn Mower Oil

Only lawn mowers with four-stroke engines have oil that can be checked and changed. You should check the level and top it off if necessary before each mowing session.

If your four-stroke engine lawn mower is new, change the oil after the first three to five hours of use. As parts of a new engine wear initially, the internal movement of parts releases tiny metal filings into the oil that will cause excess wear if left there.

  • Walk-Behind Mowers: Change oil in mower at least once a season or every 50 hours of use.
  • Riding Mowers: Change oil in mower at least once a season or every 100 hours of use.

The owners manual for your lawn mower lists the amount of oil required, but youll do fine following the dip stick or oil level mark thats part of every four-stroke lawn mower engine.

Is Sae 30 The Same As 5w30

To be clear, SAE 30 and 5w30 are not the same. SAE 30 is a single-grade oil meaning it is only rated one time at a very high temperature. This high-temperature rating is right in the middle at 30. 5w30 on the other hand, is a multi-grade oil that has two ratings. Meaning at high temperatures it is also rated at 30, but at low temperatures, it has a rating of 5. This low-temperature grade is marked by a w representing a winter rating. These are the technical differences but Ill talk more about the traits and uses of each in the next sections.

Now that you know what kind of engine you have, you can now choose the type of oil.

Today, the highest oil quality that will work with any four-stroke engines is the standard oil for cars and trucks. On the other hand, any two-stroke motor oil for air-cooled engines, like chainsaws and water pumps, is perfect for your two-stroke lawnmower engine.

You also might need to consider the temperature and climate in your area when choosing the right type of oil.

  • SAE 30 This type is ideal for warmer temperatures and most common for small engines.
  • SAE 10W-30 This type is for varying temperature range this oil improves cold-weather starting. However, it may increase oil consumption.
  • Synthetic SAE 5W-30 This oil is the best protection at all temperatures less oil consumption.
  • SAE 5W-30 This is recommended for extremely cold temperatures.
  • Vanguard 15W-50 This is also for varying temperature range and for continuous use .

Always use a high-quality detergent oil classified as For Service SF, SG, SH, SJ or higher when buying oil for your lawn mower, and remember not to use special additives. Using synthetic oils is acceptable at all temperatures, and it does not alter the required oil change intervals.

Lawn Mower Oil: What To Use

Q& A : What Kind Of Oil Does A Lawn Mower Use? &  More Questions

Lawn mowers are excellent household and professional equipment required for clearing your lawn and keeping it neat and well-manicured all season. But gas lawn mowers need proper maintenance to keep working well, and will also help extend its life span. When it comes to the maintenance of your lawn mower, one of the essential things you must pay attention to is the type of oil that is compatible with your mower engine. It is also crucial to make sure that the type of oil you decide to use is ideal and best for your specific lawn mower. Not all lawn mower engines accept any kind of oil, some are designed to be selective and can only work with a specific kind of oil. Since the oil is responsible for driving the engine, it is critical that you pay special care to this factor as the wrong type of oil will lead to the breakdown of the engine, and this is something you definitely want to avoid.

Lawn mower oil, what to use:

For smaller lawnmowers use high-quality mall engine detergent oil classified as SF, SG, SH, SJ or higher. Do not use any special additives, but rather use synthetic oils as these are acceptable at all temperatures. Check the lawn-mowers owners manual what they recommend. For big lawn mowers with a big engine, motor oil that is also used for your car can be used, but also in this case check the owners manual.

    What Kind Of Oil Does My Craftsman Lawnmower Use

    Craftsman lawnmowers use SAE 30 oil, which is the standard small engine oil. This is a type of all-purpose oil that can be used in push mowers and riding mowers.

    Craftsman mowers can also use synthetic 5W-30 oil because it protects the engine for longer in all temperature conditions. Briggs and Stratton also recommends 10W-30 oil, but in temperatures higher than 80 degrees Fahrenheit, the engine begins to consume more oil. Synthetic 5W-30 oil is recommended for use in only winter weather conditions.

    Using the wrong kind of oil in a lawnmower can damage the engine and lead to costly problems. Although car engines work by the same combustion principles, car oil should not be used in lawn mowers. Oils come in different viscosity levels, which is the thickness of the oil. SAE 30 is a thicker oil than a SAE 20 oil. Be sure to always check oil levels before using a Craftsman lawnmower.

    The Viscosity Of The Oil

    Increased oil consumption can be caused by the wrong oil viscosity grade.

    The different lawnmower manufacturers have different specifications of the kind of oil you should use.

    Thus, trust their instructions to prevent any damage from occurring.

    This will help to reduce the burning of oil or the lawnmower being slow.

    Sae 30 Vs 5w: Whats The Difference

    Oil is the lifeblood of the engine and when changing it out or topping it off, you want to be sure that youre using the right kind. This is where the oil grading system comes in. Although it might seem confusing at first, there is a pretty clear pattern that the Society of Automotive Engineers follows when categorizing motor oil.

    To grade oil, the viscosity/weight , is used. The ratings go from 0-60 with the lowest numbers representing the thinnest and the highest numbers representing the thickest oils. The question of SAE 30 vs 5w30 might seem to be confusing since they have one of the same ratings, but theyre actually a bit different.

    Can I Use 5w 30 In My Lawn Mower

    4.4/55w 30 willuse 305w305w30 willlawn mower

    Yes! We have modified our engine oil recommendations to state that you may now use a synthetic 5W30 or 10W30 oil in all temperature ranges. Keep in mind that the use of synthetic oil does not prevent you from performing your regularly scheduled lawn mower maintenance .

    Beside above, can I use 5w30 instead of SAE 30? 5wâ30 is fine to use. It has the same flow rate as SAE30 at normal operating temps. The way oil works is, the first number is flow rate at ambient temp. The second number is flow rate at operating temp of the engine.

    Similarly, it is asked, can I use car oil in my lawn mower?

    SAE 30 motor oil is commonly recommended for use in a lawn mower engine, but the safest best is to use the type of oil your lawn mower manufacturer recommends. Often 10W-30 or 10W-40, the same motor oil types that are used in vehicles, can also be used in a lawn mower.

    Is there a difference between SAE 5w30 and 5w30?

    The W means winter. So the first number such as 5 in 5w-30 means that it flows better when cold. 10w-30 would be a bit thicker while cold. However it is important to note that the 30 is the same across all three oils, meaning that they will all be the same viscosity once the engine is at full operating temperature.

    Why Buy Special Oil For Your Riding Lawn Mower

    Newer oil is made with detergent in it. The detergent is to keep the inside of the engine clean, and carry particles to the oil filter. If you are using regular motor oil in a small engine that does not have a filter the dirt particles are circulating through the engine causing unnecessary early wear to your engine.

    Non-Detergent oil is just that, oil without detergent in it, there for the dirt particles fall to the bottom of the oil pan instead of being circulated through the engine, so when you drain the oil you are draining the dirt that was sitting at the bottom of the oil pan.

    Non-Detergent oil is getting hard to find, and one of the best places to find it is at Amazon. I will go through about 5 cases of non-detergent oil in a single mowing season performing routine maintenance on customers lawn tractors. If you are having a hard time finding it, and would like to keep a few bottles on your garage shelf consider buying a case of 6 Qts Valvoline non-detergent 30W oil from Amazon.

    How Much Oil Does A Lawn Mower Take

    If you can put too little oil in your lawn mower, then its also possible that you can have too much of it. The consequence of overflowing your mower with oil includes release of white smoke and oil leakage. You might also experience your engine not starting.

    Again, there is no one standard oil level for every lawn mower it depends on each ones specifications. However, there are some rough estimates that you can use as a guide when filling up or changing your lawn mower oil. Walk-behind mowers or push mowers would normally require about less than a cup of oil some may need about 15-18oz of oil, while others may require 20-24oz. Riding lawn mowers, on the other hand, would need a lot more than what smaller mowers require. Although there are a lot of differences among models in this type of mower, generally, riding lawn mowers would need about more than a cup of oil.

    To get the specific amount of oil for your particular lawn mower, refer to your manufacturers manual or guide.
