Is SAE 30 oil the same as 5w30 oil?



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.

Can I use SAE 30 in place of 5w30?

Both oils have a “30” hot viscosity rating. This means SAE 5W-30 oil has the same flow rate as SAE 30 at operating temp. So, technically it’s fine to use SAE 5W-30 oil in place of SAE 30.

What replaces SAE 30 oil?

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.

Can you use SAE 30 in car?





SAE 30 and 10w30 are both good choices for motor oil. SAE 30 works well for older cars and for people that live in warmer climates, while 10w30 is great for varied temperatures or year-round use. There are many similarities and there are some big differences that may impact the way they work for your vehicle.

What is a SAE 30 oil?

SAE 30 is the name of the SAE class according to which the engine oil was classified. These are monograde oils which are mainly used at temperatures above freezing point. SAE 30 oils do not have good cold flow properties. Use them only in spring, summer and autumn.

What does SAE stand for oil?

the Society of Automotive Engineers

A letter for every lubricant type



Oil viscosity is very important and is affected by temperature. 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.

What happens if you put the wrong oil in your car?





Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.

What oil can be substituted for 5w30?

Both 5w30 and 10w30 engine oils have a similar SAE rating, meaning that they will perform the same at high or operating temperatures. The digit 30 indicates the viscosity of the oils when in high temperatures. 10w30, however, will thicken more when in a cold climate. 5w30 is much suitable during the cold season.

Is SAE 5w30 synthetic oil?

Note: SAE 5W-30 Full Synthetic Motor Oil is available in bulk quantities at substantial savings. Use of bulk oil products is environmentally proactive.

What oil is thicker than SAE 30?

SAE 30 and SAE 40 are both single-grade motor oils that have been rated once at a high temperature. At room temperature, these oils will have a thickness or viscosity that is pretty similar, but when hot, SAE 40 will be more viscous than SAE 30.

Can I put SAE 5w30 in my car?

You should always use the oil recommended by your vehicle’s manufacturer. However, 5w30 oil can function in temperatures as low as -30ºC and as high as 35ºC, making it an ideal choice if you drive your car in a place with relatively high seasonal temperature variations.



Is SAE the same as synthetic oil?

Is SAE Oil Synthetic? SAE oils can be synthetic or otherwise. Having the SAE designation simply means it complies with the SAE standard.

Can you mix synthetic oil with regular oil?

So, can you mix synthetic oil with regular oil? Yes. If it’s something you do only occasionally, mixing shouldn’t damage your engine. Let’s say you want to top off your oil, just to keep you rolling until your next regularly scheduled maintenance check.

What is SAE 5W 30 engine oil?

5w30 is a motor oil that is widely used in light-duty petrol and diesel engines. Like most motor oils produced today, 5w30 is a multi-grade oil, meaning it ranges from a lower viscosity grade of 5 to a higher viscosity grade of 30.

Can I use SAE 30 instead of 5w20?

Yes. Using a higher viscosity oil such as 5w30 will not harm your engine temporarily. However, car manufacturers work closely with industry oil experts like the SAE to establish consistent standards for producing accurate fuel efficiency and operating conditions for your engine.

Is SAE and synthetic oil the same?

Is SAE Oil Synthetic? SAE oils can be synthetic or otherwise. Having the SAE designation simply means it complies with the SAE standard.



Can you mix SAE and synthetic oil?

Yes, you can safely mix synthetic and conventional oil. All motor oil, whether synthetic or conventional, is a combination of base oils and additives. Each are designed to be used in the same applications, so they each pass the same minimum standards.

Is SAE 5W-30 synthetic oil?

Note: SAE 5W-30 Full Synthetic Motor Oil is available in bulk quantities at substantial savings. Use of bulk oil products is environmentally proactive.
