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.

Similarly, is SAE 30 oil the same as 10w30?

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'.

Also, is SAE 30 oil synthetic? Royal Purple SAE 30 Synthetic Engine Oil, Qt. Formulated with premium base oils combined with proprietary additive technologies, Royal Purple is a high performance motor oil that optimizes engine performance while providing superior protection.

Keeping this in consideration, is SAE 30 motor oil 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. 5W means that the oil at cold temperatures acts like a 5 weight thinner oil.

Which oil is thicker SAE 30 or 40?

The Society of Automotive Engineers (SAE) developed a scale for both engine (motor oil grades) and transmission oils. This number represents the oil's resistance to thinning at high temperatures. For example, 10W-30 oil will thin out at higher temperatures faster than 10W-40 will.

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.

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.

Can I use 5w30 instead of SAE 30?

If you had 5w30 it would get flowing much faster, therefore protecting your engine better. So you may ask why not use 0w-30 or 5w-30 all year? Yes they both end up being 30 weight when up to temp, so it is okay to run thin oils in hotter climates.

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.

Can you use SAE 30 motor 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.

What is the best oil for lawn mowers?

Amsoil synthetic oil for small engine vehicles will offer much better protection than conventional motor oils. Depending on which temperatures you operate in, you may have different requirements for your engine oil. For most mowers and weather conditions, your best bet is going to be SAE 30/SAE 10W-30 oil.

What is equivalent to SAE 30 oil?

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 5w30 motor oil in a lawn mower?

5w 30 will work. It is really too light, and you should use 30 wt. 5w30 maintains its viscosity over extreme temperature changes. When its hot, 5w30 will get too thin to properly lubricate your lawn mower.

What is SAE 30 oil 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.

Is SAE 5w30 synthetic oil?

The petroleum base oil alone may have the properties of an SAE 5 grade oil. This means at extremely low temperatures, it may be thick, and at high temperatures, it's fairly thin. When it's brand new, a 5W-30 conventional motor oil acts exactly like a 5W-30 synthetic motor oil.

Does it matter what 5w30 oil I use?

If your car takes 5w30 oil and you put 5w30 oil in it, it'll be fine. Totally wrong, these days the spec compliance of an oil is often more important than the viscosity. Don't put any 5w30 in, put the correct 5w30 in.

Is it OK to use SAE 30 instead of 5w20?

5W-30 and 5W-20 motor oil both feature the same winter rating. This means that once the engine reaches normal operating temperature, 5W-30 oil will be thicker than 5W-20. Due to the increased resistance of the thicker 5W-30 oil, your engine will produce slightly lower fuel economy and horsepower output.

What oil should I use in my Briggs and Stratton engine?

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. Fill to mark on dipstick.

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!

What is the difference between SAE 30 and SAE 40 oil?

If a liquid has high viscosity, it means it will take a longer time to flow whereas liquids with low viscosity flow faster. The motor oil grade is usually written as follows “XW-XX”. For example: SAE 10W-30, SAE 10W-40 or SAE 30. It represents how quickly the oil will thin out at a higher temperature.

What does 30 mean in 5w30?

In a 5W-30 for example, the number before the W describes the viscosity of the oil at low temperatures. The lower the number, the thinner the oil and the better the oil's cold temperature/ cold start performance. The number after the W describes how thick the oil is at the engine's normal operating temperature.
