The engine’s oil is its lifeblood. You want to make sure you are using the correct type of oil when you change it or top it off. The oil grading system is here to help. It may seem complicated at first but there is a clear pattern that the Society of Automotive Engineers follows when categorizing motor oils.
The viscosity/weight is what is used to grade oil. It measures how easily the oil can flow. The ratings range from 0-60, with the lowest number representing oil that is thinnest or least viscous and the highest representing oil that is thickest or most viscous. Although they share the same rating, it might seem confusing to ask about SAE 30 and 5w30. However, they are quite different.
SAE30 vs. 5w30
While SAE 30 and SAE 5w30 have the same viscosity or rating of 30, they are different when cold. They have slightly different uses. SAE 30 is most commonly used in small engine oils, while 5w30 is mostly used in the automotive industry. 5w30 is a multi-grade oil that can withstand very cold temperatures. This makes it suitable for cars but not for lawnmowers.
Is the SAE 30 equivalent to 5w30?
SAE 30 is not the same as 5w30. SAE 30 is a single grade oil, meaning that it can only be rated once at very high temperatures. The high-temperature rating of 30 is the middle. 5w30, on the other hand is a multi-grade oil with two ratings. It is rated at 30 at high temperatures and 5. At low temperatures, it is rated at 5. The low-temperature rating is indicated by the “w”, which stands for winter rating. These are technical differences, but I’ll discuss the characteristics and uses of each in the following sections.
The Characteristics and Benefits of SAE 30
Briggs & Stratton 100005 SAE 30W Engine Oil – 18 Oz
- Oil of high quality SAE30
- For higher operating temperatures in air-cooled engines, specially formulated
- This OEM oil will ensure that your Briggs and Stratton equipment performs at its best.
SAE 30 is the traditional small-engine oil. It’s simple to use and affordable because it is a single-grade oil. SAE 30 is a well-known grade for lawn mowers. It works in most temperature ranges. SAE 30 is a good choice for grass cutting because it can be used in cold-starting and under very cold conditions. SAE 30 may not be the best option for snow blowers. Multi-grade oils are more effective in temperatures close to freezing.
5w30’s Characteristics and Its Benefits

- 32 Oz. 32 Oz.
5w30 oil has a low winter rating and can withstand extreme cold temperatures. This is an important property, especially for vehicles, planes, and other machinery that work hard all winter. 5w30 helps to keep engines from freezing by maintaining a high viscosity even at low temperatures. This oil grade isn’t widely used in lawnmowers because it is more common to be used in warmer climates. However, this doesn’t mean you can’t use the oil in your mower.
Commonly Asked Questions about These Oils
There are many common questions regarding the properties and use of different oils. This is because there are so many numbers and letters that can be used to define them. Here are the two most frequently asked questions about SAE 30 or 5w30. Let me give you both a clear answer.
Can I use SAE 5w30 on my Lawn Mower?
You can use SAE5w30 in your lawnmower, but should it? I would advise against using 5w30 in your lawnmower unless it’s going to be working in very cold conditions. You can also compare to see if you prefer a multi-grade oil. Briggs & Stratton has a oil finding tool that can give you a general idea of the best oil to use, even if you don’t own one.
Can I use SAE 30 instead of 5w30 on my Mower?
Most lawn mower engines will work fine with SAE 30, vs 5w30. There are three things to keep in mind. How old is your mower? Newer mowers are designed with multi-grade oils in mind. Manufacturers may recommend SAE 30 over 5w30. Here’s the next thing: make sure to read the manufacturer’s instructions. Although it can be difficult to find them, it is worth the effort. Consider the weather in your area. SAE 30 should work fine if it doesn’t get cold (or even near freezing).
