The designation "10W-40" indicates a multigrade oil that is toward the low end of the SAE scale in cold weather, but at the upper end in hot conditions. 10W-40 oil is therefore good for a wide range of weather conditions. Cathryn Chaney has worked as a gardening writer since 2002.
Is it OK to use 10W40 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.
Is it OK to use 10W40 instead of 5w30?
Your vehicle does not use 5W-30 oil. 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.
Can I use 10w40 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.

How do I choose oil grade?
Always choose an oil from a brand that displays the starburst symbol that indicates the oil has been tested by the American Petroleum Institute (API). You'll also notice a two-character service designation on the container. API's latest service standards are SP for gasoline engines and CK-4 for diesels.
What is high mileage for a car?
What is a High-Mileage Vehicle? Normal vehicle use is capped at 12,000-15,000 miles per year. If you exceed that amount, your car is considered high-mileage right off the bat, even if it's only a year or two old, so high-mileage doesn't necessarily equate to age.
Is 10W40 better than 20W50?
Is 10w40 good for high mileage? 10W40 is not better than 20W50 for high mileage. The difference between 10w40 and 20w50 is simply that the latter is thicker. As far as gas mileage goes, no oil will improve your gas mileage by changing from 10W40 to 20W50 or vice versa.
Can we use 20W50 instead of 20W40?
20W40 is suitable for hotter climates and will not cause sludge as opposed to 20w50 which is more appropriate for hotter conditions. But, it has more drawbacks than 20w40. For example, it will only pass two or three cold starts in a colder climate but nothing beyond that.
What is meant by 4T in engine oil?
Engine and Gearbox are lubricated with dedicated Engine Oil and Gear Oil respectively. However, in a 4-Stroke 2-Wheeler (also called 4T Motor Cycle) you have a wet-clutch, Engine and Transmission all lubricated by a common oil.
What is the difference between 10w30 and 10w40 oil?
The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature. Using an oil with a low viscosity can lead to excessive metal to metal contact between moving parts.
What happens when you put 10w30 in a 5w30 engine?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.
Is too much engine oil bad?
“Too much oil can damage your engine. If you notice an overfill of oil, the excess should be drained out of the engine. Therefore, we recommend checking your dipstick regularly.”
Is 10w40 thicker than 5W40?
The main difference between the two oil types is that one is thinner than the other. The 5W40 is thinner than the 10W40 at lower temperatures. 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.
Why is 5w30 more expensive than 5W40?
5w30 is a multi-graded oil which is suitable to use in lower temperature. 5w40 is crude oil which can be used in a vehicle which has unleaded and leaded gasoline. 5w30 is an expensive engine oil as compared to 5w40. 5w40 is not expensive engine oil.
