Is SAE 30 the same as 10w30?



10w30 is thinner than SAE 30. The “30” means that it has the same viscosity as the other when the engine is hot. However, since it is thinner, it will never become as thick as SAE 30 when it gets cold. 10w30 has a viscosity of 10w which means it will start moving and protecting engine parts at a colder temperature.

Can I substitute SAE 30 for 10w30?

Can I Use 10w30 Instead of SAE 30 in My Lawn Mower? You can use 10w30 instead of SAE 30 in your lawn mower if you want. Since 10w30 has the same viscosity grade at operating temperature, you won’t run into any problems by using it instead of SAE 30.

What is SAE 30 equivalent to?

Obviously, SAE and ISO use two different scales to measure viscosity. SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100.

What does SAE 30 mean in oil?





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.

Can I use 10w30 in lawn mower?

Lawn Mower Oil Types



10W30 is a common motor oil grade suitable for many lawn mowers. Your owner’s manual will tell you the exact grade required, but in almost all cases 10W30 is the right stuff for a four-stroke engines. Any brand of oil that’s suitable for cars or trucks will work fine in your mower.

What can I use instead of 10w30?

Can you use 5W-30 instead of 10W-30? Absolutely yes for car engines, 5W-30 is usually synthetic and superior to 10W-30. Both have the same viscosity at the operating temperature of an average car engine. 5W has lower viscosity when cool and is considered better for the car engine during engine start.

What does SAE stand for oil?

the Society of Automotive Engineers





A letter for every lubricant type



Therefore the first three letters you need to know are SAE, the acronym of the Society of Automotive Engineers. This society is responsible for establishing a classification system based solely on oil viscosity.

Is SAE 30 oil synthetic?

SAE 30 High Performance Synthetic Motor Oil.

Is SAE 30 oil the same as 10w40?

SAE 30 is a medium thickness, single-grade oil that is mostly used in small engine machinery such as lawn mowers and string trimmers. 10w40 is an oil that is mostly used in diesel engines and motorcycles. This is because 10w40 is slightly thicker when hot, and also rated for use in cold temperatures.

Is SAE 30 the same as 4 stroke oil?

The standard oil used for 4-stroke engines found on petrol lawnmowers is grade SAE 30.

When should I use 10W30 oil?

The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold, and 30 when the engine is hot.



Should I use thicker oil in an older engine?

A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well.

Can I use 5W-30 instead of 10W30 in my Honda lawn mower?

Running Cold



If your mower manual calls for a 5W-30 engine oil, using a 10W-30 oil is also acceptable. The only difference between the two oils is the low temperature point, with the 5W-30 functioning slightly better than the 10W-30.

Can I use SAE 30 in Honda lawn mower?

Because lawn mowers are not used in sub-zero temperatures, Honda and Mobile Oil both recommend standard 10W-30 oil for your Honda lawn mower. SAE 30-weight oil is in the middle of the SAE ratings. SAE 10 and 20 may not provide the high heat protection your engine requires.

Is all SAE 30 oil the same?

Performance. Thinner oils perform better in colder weather, especially when starting a car. Thicker oils perform better at higher temperatures. Single-grade oils, such as SAE 30, are thicker than lower grades, and in this case has a viscosity rating of 30 at a temperature of 100 degrees Celsius.

Does SAE 30 oil have detergent?

SAE 30 Non-Detergent Lubricating Oil is formulated using 100% pure, virgin base oil. Non detergent chemistry ensures there is no material in the formula to create deposits on metal surfaces ensuring clean operation.



Can I use 10w40 instead of 10w30?

The short answer is yes. Because both oils are formulated to give the same performance, it will be safe for you to use either oil. Some differences between the two oils include viscosity and base oil.

Is SAE 30 thicker than 10w30?

10w30 is thinner than SAE 30. The “30” means that it has the same viscosity as the other when the engine is hot. However, since it is thinner, it will never become as thick as SAE 30 when it gets cold. 10w30 has a viscosity of 10w which means it will start moving and protecting engine parts at a colder temperature.

What happens if you mix oil weights?

Can oils of different grades be mixed? The good news is that mixing different types of oil it will not harm your engine in any way in the short run. Most synthetic and semi-synthetic engine oils are based on regular oil and are compatible.
