SAE 30 oil is a motor oil that has been given a viscosity rating of 30 by the Society of Automotive Engineers, according to AA1Car Automotive Diagnostic Help Center. Motor oils typically have ratings from 0 to 50..
Likewise, is SAE 30 the same as 5w30?
No. SAE 30 is a single viscosity motor oil. Only multi viscosity motor oils only should be used in any car. 5W30 is motor oil that is thinner when cold than 30 weight motor oil and thicker than 5 weight motor oil when hot.
Additionally, what is the difference between SAE 30 oil and 10w30 oil? Nope. SAE 10W30 is an oil that has SAE 10W viscosity(thickness) at low temperatures, and SAE 30 viscosity at high temperatures. SAE 10W30 is an oil that has SAE 10W viscosity(thickness) at low temperatures, and SAE 30 viscosity at high temperatures. The W stands for 'Winter'.
Accordingly, 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.
Can you use SAE 30 oil in a car?
It is pefectly fine to use SAE 30 oil in place of the 10W30, as long as you never let the oil get below degrees 50C. SAE 30, has a certain 'slipperyness' when it is hot. (100 degree c measured), so when your car is running at normal temperature the oil flows properly.

Can I use 5w30 instead of SAE 30 in my lawn mower?
5w-30 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.Can you use car oil in a 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.Can I use 10w30 instead of SAE 30 in my lawn mower?
Yes; you can make use of it. But there are other factors you need to consider. These include temperature and the engine. Older engines can use the SAE30, while the 10W30 is for modern engines.What is SAE 30 used for?
SAE 30 w is usually a (non detergent) motor oil that is usually used on small engines like lawn mowers, generators, and other 4stroke lawn and garden tools. 30 is the viscosity or how think it is. on most iols that will vary with temp, like a 5w-30 will be much thinner at colder temps than say a 30w-50 oil.Can I use 5w 30 in lawn mower?
Yes! We have modified our engine oil recommendations to state that you may now use a synthetic 5W30 (100074WEB) 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 (i.e. check oil, change oil, etc.).Can I use 5w30 in lawnmower?

No you cannot use Motor Oil in a Hydraulic System. Motor Oil runs at a much higher temperature and Hydraulic Oil starts to fail at around 45c. You cannot as water is one of the worst contaminates for Hydraulic Oil. The system would break down and would cost even more to repair than using Motor Oil.Is SAE 5w30 synthetic oil?
The petroleum base oil alone may have the properties of an SAE 5 grade oil. When it's brand new, a 5W-30 conventional motor oil acts exactly like a 5W-30 synthetic motor oil.Can I use 10w 30 in a lawnmower?
Yes you can use 10w30 in a lawn mower engine, however oil type recommendations will vary between makes and you should of course use the oil type specified in your users manual.What oil does a Briggs and Stratton engine take?
Use Briggs & Stratton SAE 30W Oil above 40°F (4°C) for all of our engines. Check oil level regularly. Air-cooled engines burn about an ounce of oil per cylinder, per hour.Is SAE 30 thicker than SAE 40?
The lower the number here, the less it thickens in the cold. So 5W-30 viscosity engine oil thickens less in the cold than a 10W-30, but more than a 0W-30. Monograde oils such as SAE 30, 40 or 50 are no longer used in latest automotive engines, but may be required for use in some vintage and antique engines.What type of oil goes into a lawn mower?
SAE 30- Warmer temperatures, most common oil for small engines. SAE 10W-30- Varying temperature range, this grade of oil improves cold-weather starting, but may increase oil consumption. Synthetic SAE 5W-30- Best protection at all temperatures as well as improved starting with less oil consumption.Is all SAE 30 oil the same?
1./ There is no such thing as SAE 30w! The SAE J300 spec refers to SAE 20W and below and SAE 30 and above. There is no low temperature requirement for SAE 30, only a viscosity at 100 degrees C. 2./ 30 oil or 30 weight oil means nothing at all!Can I mix SAE 30 with 10w30?
You can mix straight weights like SAE 10 and SAE 30 or multi-grades like 10W30 and 10W40. Run your straight 30 during the summer if you want to.What is Small engine oil?
SAE 30- Warmer temperatures, most common oil for small engines. SAE 10W-30- Varying temperature range, this grade of oil improves cold-weather starting, but may increase oil consumption. Synthetic SAE 5W-30- Best protection at all temperatures as well as improved starting with less oil consumption.Is SAE 30 non detergent oil?
Valvoline Non-Detergent Motor Oil SAE 30 is a general purpose non-detergent engine oil.What weight is SAE 30?
SAE 30 oil is a motor oil that has been given a viscosity rating of 30 by the Society of Automotive Engineers, according to AA1Car Automotive Diagnostic Help Center. Motor oils typically have ratings from 0 to 50.Can I use 20w50 oil in my lawn mower?
The short answer is yes, you can use 20w50 oil in a lawnmower but results may vary. This kind of oil is not designed specifically to be used in a lawnmower. 20W50 is actually a fairly specialized petrol engine oil formulated for use in engines made generally before 1980.Can I use 10w40 instead of 10w30 in my lawn mower?
The only difference between 10w30 and 10w40 oil is their thickness at engine operating (hot) temperatures. In the past, it was common practice to switch to a higher viscosity oil as an engine got older, for example, using a 20w50 oil in place of the 10w40 recommended by the manufacturer.
