As per API recommendations (1) for car engines, you can use 10W - 30 oil if the maximum expected outside temperature is above -18 . The time it takes to flow through the tubing is used for the number after the "w." A 10w40 oil takes 10 seconds longer to flow through the tube during this test than a 10w30 oil. When the oil is cool, the 10w30 oil would be thicker and more viscous than the 5w30. 5W20 oils have a winter viscosity grade of 5, which means that it is less viscous at extremely low temperatures compared to 10W30. Thicker oil offers better lubrication of motor and engine parts. In other words, it has higher viscosity when it is cool. The viscosity, or thickness, of the oil, affects how .

Subsequently, question is, is there a big difference between 5w30 and 10w30? Likewise, is there a big difference between 5w30 and 10w30? They may have similar thicknesses at operation but huge differences at start-up even here in Florida. It depends on the car type because all oil comes for a particular purpose. Which Is Better, 15w40 or 10w30 Oil? What Is 20w50 Engine Oil? 5W-30 VS 10W-30. It features additives that help reduce friction by acting as a sealer among the engine parts.

It will protect your engine from higher temperatures. Several people have now mentioned that M1 10W-30 is "thicker" than 5W-30, well, oils with a wider temperature range are "thicker" (meaning a 0-30 is thicker than a 5-30, and a 5-30 is thicker than a 10-30 but not more "shear resistant) . At operating temps 10W-30 will act like 30W and therefore actually be thicker than ISO 46. Which oil is more viscous 5W-30 or 5w40? Is there a big difference between 5w30 and 10w30? Which is thicker 5w30 or 10w40? Both have almost the same characteristics, and the only difference is the oil viscosity. Oil DOES NOT get thicker as it warms up. Which oil is better 5w30 or 5w40? If the lawn mower engine is a 4 cycle engine, SAE 10W30 or 5W30 oil areideal picks. Car manufacturers conduct several . So, it can easily flow to the top ends when cold. If you are using the car at high temperature, then choose 20w40 engine oil. The 10w30 motor oil is engine oil with a viscosity of 10w if the engine is cold. at less thickness than 10W30. That's just a general overview of the difference between 10w30 and 5w30. The 5w30 when cold will still be thicker than the 10w30 when hot anyways so it doesn't matter. The comes the type like mineral oil, semi syntheti. The thickness or measurement of the oil viscosity becomes easy when reading the numbers like 10W30 will help know oil weight. This is important because viscosity changes as temperatures change. While 10W 30 oil is a good option for some vehicles, 5W 30 oil is a better choice for most vehicles. At lower temperatures, it's thinner. . . This means, they behave like 10W weight oils in . Which oil is better 5w30 or 10w30? Remember that using oil with a viscosity that is too high can result in excessive oil temperature and increased drag. Should I Use Thicker Oil In An Older Engine? At operating temperatures, both .

It would become slightly thick but also help the engine start quickly when the weather is cold. The operating temperature of 10w30 is more common than the operating temperature of 10w40. S o both the oils 5W-30 and 10W-30 have exactly the same viscosity (SAE 30) when your engine is running, and will perform in the same way. What is thicker than 10w30? The engine oil will flow slower than 5w30 during the cold season. 5w30 is used for light-duty engines while 10w30 is used for engines which carry heavier loads.

Viscosity decreases as the temperature of the oil increases. 29 oct 2021. When it comes to car oil, there are a few different types that motorists can use. On the other hand, it has a hot viscosity grade of 20. 10W-30 oil can survive in a temperature as low as -13F and as high as 86F. Heavier oil will be thicker than lighter oil. So these oils act like an SAE 10W single grade oil at lower temperatures. Likewise, is there a big difference between 5w30 and 10w30? All the motor oils today already can improve fuel economy. 10w30 provides sealing action in the engine due to the fact that it is thicker than 5w30 engine oil. The difference between these oils is their viscositythe thicker the oil, the harder it will be to flow. . As per API recommendations (1) for car engines, you can use 10W - 30 oil if the maximum expected outside temperature is above -18 . These two oils are used for. Answer (1 of 22): No, 10 signifies lowest temperature and 30 or 50 shows highest temperature at which engine oil would retain its viscosity and would run smoothly. Using the wrong motor oil viscosity, especially if thicker than . SAE30 is engine oil equivalent to 10W30 oil, but SAE 30 oil has a higher viscosity (thickness) rating than 10W30 oil, meaning it is thicker and less likely to flow at low freezing temperatures. However, in the 2 cycle engine but for superior cold cranking, SAE 10W30 oil works much better than the SAE 30. If you are looking for an all-purpose option, your 10w30 is the best option. Focusing more on the second part of the rating - the '30' versus '40' - we know that the engine oil with a 10W40 rating will be able to retain its 'thickness' or viscosity a lot longer than the . This means that when you pour 10W40 into your engine, it will have a harder time flowing through the engine and moving around the parts. A 5w30 oil will flow very easily when cold and maintain its viscosity at high temperatures better than a 10W30 oil. Therefore, high quality additives are needed to compensate for those weaknesses in order for a 10W-30 engine oil to protect as well and last as long as a 15W-40. Is 10w30 thicker than 5w30? This enables the 5w20 motor oil to reach engine parts quicker and create less drag that reduces fuel economy. For 5w30, the viscosity of the oil according to SAE grade is 5 in lower temperatures (-18 degrees celsius). Generally Better In Warm Weather. The difference between 10W-30 and a 10W-40 is the high temperature viscosity. However, the 10W - 30 oil will be thicker when it is cold. Keeping this in mind, which is 5w30 or 5w40 thicker? Both are multi-grade oils; however, 5w30 is thinner and faster-flowing oil, making it better suited for light-duty vehicles, while 10w30 has a thicker, slower-moving composition ideal for heavy-duty engine applications. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.

See the link below to a chart that may help demonstrate this. 10W30 is a thicker oil. Thin oil and heat don't go well together, to say the least. What is 10W-40 Good For? Even though it's thicker than 5w40, it's still considered a light oil. So, if you are in a tropical region or a warmer climate area, you should add 20W50 engine oil. The 10W30 has high viscosity level so it is quite thick in summer. . you should know that the cold viscosity of a 10w40 oil is a lot thicker than the 10w30 oil even though . As 5w30 is much thinner than 10w30 because of the low viscosity, it can protect . This oil is suitable for engines with a high mileage. Thicker oil generally lubricates engine parts better than thinner oil. Because 10W-30 is thinner than 15W-40 oil, its film strength can be weaker and it can be more prone to oxidation. The slightly thicker oil film from the heavier base weight oil 10W can help protect worn engine bearings as well. For example, a 5W-40 oil will be thinner in cold temperatures than a 15W-40, but at normal operating temperatures both oils will flow the same. The 5w30 when cold will still be thicker than the 10w30 when hot anyways so it doesn't matter.

Obviously, a 10W-40 is thicker than a 10W-30 at high temperature. As the grades indicate, 10W30 engine oil has a higher viscosity than 5W30 engine oil. 1 Answer: Ariel. It has thirty if the engine is hot. When at high temperatures, the 5w30 oil becomes thinner than the 10w40 oil since 30 is lower as compared to 40. In other words, it also means that the oil is thicker at the operating temperature. 10w30 is easier to find and much less expensive than 10w40. It is important to remember that, these numbers do not depict the actual viscosities of the oils when at extreme temperatures. Which is thicker 10W30 or 10w40? At lower temperatures, it's thinner. Thicker oil generally lubricates engine parts better than thinner oil. Thicker at lower temperatures. 15w40 is thicker than 10w30, but thinner than 15w40.

In other words, when your engine is running, both 5w30 and 10w30 oils have the same viscosity (SAE 30) and will operate as well. SAE 30- Suitable for warmer temperatures, where there is no winter season. Q. For an older, high-mileage passenger car, it is recommended to switch to a thicker viscosity oil, such as 10W-30, when approaching and passing 100,000 miles, to lubricate the engine well for preservation. The slightly thicker oil film from the heavier base weight oil - 10W - can help protect worn engine bearings as well. at less thickness than 10W30. Which oil is better 5w30 or 5w40? The difference between 10w30 and 10w40 is the thickness of the oil at high temperatures, at which 10w40 is thicker than 10w30.The second number, "30" and "40" for these oils, is a rating of how effectively the oil pour at hot temperatures. However, if you use 10W40 instead of 10W30, the oil will stay . The weight of an oil refers to the thickness of the oil. . Oil that is able to maintain its thickness at high operating temperatures has many benefits to show for. For example, a Mobil One 0W-20 has a viscosity of 189 at 50 F. A typical 10W-30 mineral oil would have a viscosity of 400 at that temperature. Undoubtedly, 20W50 is thicker than 10W30 engine oil. So thicker oil would retain viscosity for longer time, making 10w50 a thicker oil. A 10w-40 is better at around 6 times thicker and a 0w-40 is much better at about 4 times thicker. This helps it lubricate older moving parts in high mileage engines while being less likely to leak. Single Grade Oil So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures. The 5w30 when cold will still be thicker than the 10w30 when hot anyways so it doesn't matter. Meaning, 10W-30 motor oil acts like an SAE 10W weight oil under 0C (32F), and an SAE 30 oil at 100C (212F). The heat will make the thick oil slightly thinner, allowing it to flow smoothly while offering adequate engine protection. This 10w30 helps your engine seal against wear that happens with old age. Furthermore, what is a thicker oil than 10w30? 10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. . Therefore, 10w-40 oil clings to the engine's moving parts more . At operating temperatures, both . About The Author Ryan McCain Ryan has got more than 15 years in the auto industry. In fact, the only major difference between 5w30 and 5w40 is the viscosity in warmer temperatures. A 10w-30 oil has the flow characteristics of a 10 weight when cold (so lube can be rushed to where it needs to go) but a 30 weight when at operating tempeature. So if the oil is already thin, then it becomes thinner. The slightly thicker oil film from the heavier base weight oil 10W can help protect worn engine bearings as well. In conclusion, 5W 30 oil is better for your car than 10W 30 oil. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures. If you want can check the in-depth discussion about the lawn mower engine oil type suggested with logical reasons.

It's made up of a blend of synthetic high-performance bases and additives that's been carefully matched. So, if you use thin oil in old engines, it will cause more oil burning than thicker oil. The reason is that at 50 or 60 F these oils are easier on your engine at start-up. For old model vehicles using 10w30 rather than 5w20 is best. Both the oils have similar viscosity at 100 degrees Celsius but 5w30 grade oil will thicken less than 10w30 grade oil in cold climate. 5w30 is also the thinner engine oil of the two at lower temperatures. Vehicle starts to burn oil as they age, so many tend to start adding-in an Oil Treatment, or a slightly thicker oil to help keep it running without burning too much oil. In a car engine, knowing the movement of the oil will help understand its uses. In addition, the other number indicates the oil's resilience to thinning at extreme temps. It will, therefore, provide better protection for the interior parts of the engines quicker than the 10w30. Is there a big difference between 5w30 and 10w30? . Therefore, 10w-40 oil clings to the engine's moving parts more .

since the viscosity of the 10w40 oil is greater than the viscosity of 10w30, it is thicker and therefore it is more suitable to use in hot weather conditions because in a hot environment an engine oil will have to bear the heat of engine as well as of the atmosphere which will make it thinner than its original form and this is the reason for not For an older, high-mileage passenger car, it is recommended to switch to a thicker viscosity oil, such as 10W-30, when approaching and passing 100,000 miles, to lubricate the engine well for preservation. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. On the other side, 10W30 is also thin, but it is thicker than 0W20 in winter. Weight .

10W40 has a higher viscosity than 10W30. 5w30 is less viscous than 10w30. Yes, 10W30 is thicker or more viscous than 5W30. In fact, the only major difference between 5w30 and 5w40 is the viscosity in warmer temperatures. It still gets thinner. What is thicker than 10w30? Sadly, that quick answer doesn't make it any easier to understand. 10w30 provides sealing action in the engine due to the fact that it is thicker than 5w30 engine oil. Both 10W-30 and 10W-40 oils have a "10W" rating an SAE grade for winter use (thus the 'W' appended onto it). A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Both the oils have similar viscosity at 100 degrees Celsius but 5w30 grade oil will thicken less than 10w30 grade oil in cold climate. Since it's a monograde oil, it's used over a small temp range. The lower the kinematic viscosity number, the thinner the oil. The viscosity of this oil is rated at 50 at high temp and it drops down to 20 at lower temp. This makes 10W-30 oil pretty stable at higher temperatures and pressure, and can run through critical engine parts without causing too much friction. However, 5w20 is much thinner in comparison. That is usually 100C (212F) when the engine is running (in an average engine). Fuel Economy Both 5w40 motor oil and 10w30 motor oil can provide good fuel economy. Compared to 5w40 oils, 10w30 oils have a lower viscosity of 10 and a higher viscosity of 30. It has a higher viscosity, meaning it will flow more easily and provide better lubrication. The oil is thinner in case of lower weights, while higher weights show thicker oil. Which is thicker 5w30 or 10w40? Another option is 10W30, which is a thicker oil that is meant for use in older, heavier vehicles. I would still recommend checking the control linkage if you think this squeal is excessive. On the other hand, 10W30 is thicker and perfect for vehicles that carry heavy loads. 5w30 is used for light-duty engines while 10w30 is used for engines which carry heavier loads. The viscosity diferential is less from hot to cold with a 10w-30 then with a straight 30 weight. While 5W30 would save you more fuel in Winter, 10W30 would perform better when driving in scorching temps. Thickness is the significant difference between 10W30 and 10W40. Because 10W-30 is thinner than 15W-40 oil, its film strength can be weaker and it can be more prone to oxidation. Using the wrong motor oil viscosity, especially if thicker than . Answer (1 of 3): SAE40. However, the 10W - 30 oil will be thicker when it is cold. Furthermore, is there a big difference between 5w30 and 10w30? A higher viscosity oil, such as 10w30, will flow slower at low temperatures compared to a lower viscosity oil like 5w30. 5W-30 VS 10W-30. However, when you compare a 10W-30 vs a 15W-40, at both low and high temperatures the 10W-30 will be thinner, with less resistance to flow. A higher viscosity or thicker oil will seal better than a low viscosity oil. However, the 10W-30 oil will be thicker (higher viscosity) than the 5W-30 when it is cool. This will result in improved performance and reduced wear and tear on your engine. Owing to the lower viscosity of the oils at low temperatures, they have a higher resistance to flow. Therefore, high quality additives are needed to compensate for those weaknesses in order for a 10W-30 engine oil to protect as well and last as long as a 15W-40. . 10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. This number is particularly important for vehicle startup when the engine is still cold, and the oil needs to flow quickly to lubricate it. The 10W-40 engine oil has a thicker viscosity than, say, 10W-30 oil when the car engine is hot. 1 Answer: Ariel. A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. The 5w40 motor oil will make your consumption of motor oil very low. It is recommended for trucks, towing vans, and other heavy-duty vehicles that are subject to extreme temperature and performance. So adding a little 10W40 or 5W40 to the usual 5W30 or 10W30 thickens-up the oil and stop it from being . And when it comes to the lower temperature, 10W30 engine oil is thicker than its counterpart 5W30. When to Use 10w30 vs 5w30 The only difference between these two oils is cold flow ability: a 10w30 oil will move slower than a 5w30 oil during cold startups. That is usually 100C (212F) when the engine is running (in an average engine). It has amazed me in the past how much noise a badly adjusted or worn linkage can make. It is recommended for use at -13F up to 95F / -25C up to +35C (outside temperature). No,10W30 is not thicker than 10W40 since the latter is thicker at operating/high temperatures. The 5w30 when cold will still be thicker than the 10w30 when hot anyways so it doesn't matter. 29 oct 2021. For example, thinner oil is best during the initial stages. At operating . Is 10w30 thicker than 5w30. However, a 10W30 oil will flow better when hot than a 5W-30 oil. In the case of 10w30, you can tell the viscosity of the oil.

10w30 is the better all-purpose motor oil between 10w30 and 10w40. On the contrary, using thinner 5w20 oil is the best idea if your car can work at lower temperatures. Which is at a lower temperature of 10 and at an operating temperature of 30. 20w50 is also a multi-viscosity synthetic oil but heavier. The 5W30 engine oil is thinner than the 10W30. The "W" in both 10w30 and 5w20 stands for winter. On the contrary, in summer, oils tend to get thinner because of the high temperature. This means 5w30 grade oil will flow . At operating temperatures . The most common type is 5W30, which is a light oil that is made to protect engines against wear and tear. You will first need to know what oil viscosity is and what the numbers of both motor oils mean. 10w30 is great but more suited for low temperature. When to Use 10w30 vs 5w30 The only difference between these two oils is cold flow ability: a 10w30 oil will move slower than a 5w30 oil during cold startups. 10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. The main difference between 10w30 and 5w30 lubricating oil is their viscosity.

A 10w30 motor oil, on the other hand, is recommended for vehicles with heavy mileage. Thinner at lower temperatures. This means 5w30 grade oil will flow . The 10W30 oil - While still quite "fluid", this oil is a little bit thicker at low temperatures than the 5W30 oil, making the process of starting your engine a little bit harder. This is when the engine is in the winter season or when it is just starting. 2. 5W - 30 and 10W - 30 lubricants have the same viscosity at the operating temperature of the engine. When to Use 10w30 vs 5w30 The only difference between these two oils is cold flow ability: a 10w30 oil will move slower than a 5w30 oil during cold startups. While the engine is warming up, 10w30 oils are a great way to keep the moving parts from getting stuck. So, 10W30 might take more time to warm the engine up. . When to Use 10w30 vs 5w30 The only difference between these two oils is cold flow ability: a 10w30 oil will move slower than a 5w30 oil during cold startups. But if you are in colder areas, you should add 10W30 engine oil. It gets thinner. On the other hand, 10W30 oils have viscosity grades of 10W at lower temperatures and 30 at higher temperatures. Because it is thicker than 5w30 engine oil, 10w30 seals the engine. Oil with a 30w grade viscosity is pretty thick, which makes it ideal for using under higher temp. When you look at the first viscosity number, "10", you will appreciate that these oils have the same viscosity at low temperatures. 5W - 30 and 10W - 30 lubricants have the same viscosity at the operating temperature of the engine. 10W-40 will have a higher viscosity at operating temperatures than 10W-30. 10W-40 is thicker than 10W-30 at higher operating temperatures.
