Is 5W-30 or 40 better?
5w40 is engine oil that indicates the weight and viscosity of the engine. Its lower viscosity is 5 and higher viscosity is 40. 5w30 has lower viscosity hence it is suitable to use in hot or lower temperatures. 5w40 has higher viscosity hence it is not suitable at all temperatures.
Can I use 10W-40 instead of 10w30?
If both 10w30 and 10w40 are acceptable oil options for your car, it’s recommended that you use 10w40 for your car with high mileage. 10w40 is more viscous than 10w30. The thicker oil helps older engines handle higher temperatures and manage wear and tear more efficiently.
What’s the difference between 5W30 and 5w40?
The working viscosity of 5w30 is basically from 9.3 to 12.5mm2/s whereas the operating viscosity of 5w40 is 12.5 to 16.3mm2/s. That means 5w40 has larger viscosity than 5w30. So, 5w30 is better than 5w40.
What is the difference between 15w40 and 5w40?
The primary difference between a 5W40 and a 15W40 oil is the cold temperature performance. At operating temperatures, theoretically BOTH oils perform the same. The advantage of the 5W is upon startup. Bottom line is 5W40 gets to the nooks and crannies faster than 15W40.
Is 5w40 oil thicker than 10W40?
On the other hand, the 10W40 motor oils are thicker than the 5W40 oils for good reasons. This oil type works pretty well in lubricating engine parts during startup. However, the main difference between these two engine types is that the 5W40 can work better than 10W40 in very cold places.
What happens if you put 5W30 instead of 10W30?
In general, there are no negative or harmful effects if you used 10w30 instead of 5w30 on climates that are not on extremes. Moreover, there may be a little benefit as it is good for engines having with high mileage and contains less viscosity improvers.
