The best option for summer driving is 10W-30 because it flows more easily in hot weather. However, if you live in a very hot climate or you have an older car, 10W-40 might be a better option to help protect your engine.
Should I use 10W30 or 10W40 oil?
Using 10w30 oil in cold weather will help reduce excessive oil temperatures and drag as the engine warms up. Using 10w40 oil in the summer will help the oil stick to internal components in high temperatures, avoiding the wear and tear from metal-to-metal contact between moving parts.
Can I change my oil to 10W40 in the winter?
So, if you change your oil to 10W40 in the winter when it’s cold outside and snowing, then don’t worry because this will not affect anything on an engine. But during summertime or hot weather seasons – make sure that there are no ties with the Summer Oil Change Form available at our shop.
Which motor oil is best for cold weather?
Similarly, SAE 10W-40 motor oil performs well in cold weather conditions. It has the same low-temperature limits as the 10W-30 but is better in higher temperatures. This oil type remains thicker at 100°C/212°F compared to an SAE 30 high-temp flow grade and is more suitable for warm weather.
What is SAE 10W-30 motor oil?
For instance, SAE 10W-30 oil would act like an SAE 10 at cold temperatures and like an SAE 30 at 100 °C (212 °F). SAE 10W-30 motor oil is one of the low-temperature multi-grade oils commonly recommended by manufacturers, along with 15W-40, 5W-30, and 0W-20.
What is 5W 40 oil used for?
5W-40 motor oil. The 5W-40 viscosity is a prevalent recommendation for performance engines in European vehicles with gas-powered engines, and in American diesel pickup trucks. We offer 5W-40 oils for gasoline- and diesel-powered engines.
What is 5W-40 engine oil?
5W-40 engine oil is extremely adaptable, handling a wide range of temperatures and maintaining its efficacy both in low winter temperatures and when operating in hotter environments. WHAT DOES 5W-40 MEAN? “W” stands for winter.
What is the difference between 5w40 and 10w60?
This is one of the widest ranges; the most extensive of all (from -25 °; + 50 °) is that of oil 10W60. As with 5W30, 5W40 motor oil has a cold viscosity of 5. The major difference between them is that 5W40 has a hot viscosity of 40. It means at higher temperatures, it will be thicker than its counterpart of hot viscosity 30.
What is 5W30 lubricant?
What this means is that in cold temperatures (like in winter), your 5W30 oil will flow much more freely at the SAE viscosity grade of 5 and thickens up to 30 in hot weather. This synthetic lubricant can be used in temperature conditions ranging from -30 ° to + 35 °.
When should I use 5W motor oil?
It is recommended that you keep 5W motor oil on hand before the first gust of cold strikes. 5W viscosity grade calls for the lubricant to properly flow at lower temperatures as compared to, for instance, oil with 20W viscosity, hence you should use it when the weather is cold. When the oil heats up, it gets thinner.
Is 5W-30 or 5w40 better for winter?
5w40 is better for starting your engine at low temperatures as it flows more easily in this environment.
What oil is better 5W30 or 5w40?
This parameter determines the maximum temperature of application of the oil. Therefore, what oil is better: 5W30 or 5W40 (winter or summer), is determined precisely by this parameter. If the index is low, the lubricant should not be too viscous to perform a cold start of the motor with a starter and pump it through the pump.
What does W mean on a 5w40 engine?
For both 5w40 and 5w30, the w represents winter provided by the Society of Automotive Engineers or SAE multi grading system. The number appearing before the w is the oil’s viscosity or the thickness of the oil at lower temperatures. On the other hand, the number after the w means the oil’s viscosity at high temperature when the engine is running.
What is the temperature of SAE 5w40 oil?
In this manner, the 5w40 oil can operate at temperatures from – 35 degrees C (-31 F) to + 40º С (104 F). To achieve a more economical ride, American engineers have introduced several parameters that give the right combination of certain SAE 5w40 viscosity oils that lead to energy savings. It is imperative to reduce oil consumption by 1.5%.
Can I use 10W 40 instead of 5W-30?
Recommended Services The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.
What happens if I put 10W40 instead of 5W30?
Well, if you put 10W40 instead of 5W30, your car engine will face a different problem. Finally, faulty functions will reduce your car’s overall performance. Now, let’s figure out why you shouldn’t do this . What will happen if I put 10W40 instead of 5w30? Being a thicker oil 10W40 can harm your engine if your engine requires a thinner oil.
How many miles can you run with a 5W30 oil?
Either it is a 5W30 or any other oil, you should go for an oil change as per the user manual requirement. When you change the oil filter, change the oil as well. For assumption, you can use 5W30 for 7,000 to 8,000 miles. Do not run more than this.
What’s the difference between 0w30 and 0w40 oil?
You have maybe done some damage since the oil level with +2 quarts is still really low. The oil cools and lubricates the engine. From the other thread the difference between a 100% 0W30 and 100% 0W40 oil is about 2% fuel economy, which you won’t notice on a short run (about 0.5 mpg on a 25 mpg combined cycle).
What kind of oil should I use for my engine?
If your engine needs 10w30 motor oil, you can try 15w30 motor oil if the temperature is warm. You can go with 5w30 motor oil if the weather is cold. If the temperature is freezing, then you can 0w40 motor oil. But the bottom line is that you should always use the recommended motor oil for your engine.
