There’s no substitute for reading your owner’s manual. It will list what type of oil the automaker recommends for your car. It may also recommend different oil depending on whether you live in a hot or cold climate. The most important thing is to use oil that’s the right thickness, or viscosity, for your car’s engine.5 juil. 2015

Can I use 5W40 instead of 5w30?
‘ Yes, you can depend on the temperature range. 5W30 and 5W40 oils are mainly used for winter or cold temperature; still, they have thinner quality for the hot temperatures, like 5W30 can be used from -30° to 30° temperature range and 5W40 can be used from -40° to 40° capacity.1 avr. 2021
Is 5w30 better than 10W40?
The difference is in the viscosity of each at different temperatures. … The 5w30 oil will flow better at low temperatures than the 10w40 oil. This means that the 5w30 oil will protect the engine better at low temperatures, usually when the engine is just starting or during weather conditions such as winter.
What’s the difference between 5W40 and 10W40?
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. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity).1 avr. 2020
What happens if I put the wrong oil in my car?
Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so. Contrary to what some believe, adding synthetic oil to regular oil won’t harm the engine, but there’s also no benefit in doing so.
Can you put any oil in car?
You should use synthetic oil if you car manual instructs you to do so but otherwise, it won’t matter too much. Any oil used should be multi-grade, however. … It is also worth noting that most oils around are actually blended, not just purely synthetic or regular.4 mai 2018
Which oil is better 5w30 or 5w40?
In general, 5w30 is a great multi-grade oil for different temperature specters. It is also more fuel efficient. 5W40 is a motor oil that penetrates to the active mechanisms faster, and provides excellent lubrication on start up.
What does 5W-30 stand for?
The short answer:The numbers represent the viscosity of the oil and the W stands for WINTER. … In a 5W-30 for example, the number before the W describes the viscosity of the oil at low temperatures. The lower the number, the thinner the oil and the better the oil’s cold temperature/ cold start performance.17 jui. 2021
Is 5w40 better for high mileage cars?
5w40 is often used in cars whose engines have higher mileage and wear, which work better at higher temperatures, but also better than 5w30 at lower temperatures.
Can I replace 5w30 with 10w40?
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.21 oct. 2017
Is 10w40 good for high mileage?
With a unique blend of premium base oils and an enhanced additive system, PEAK® 10W-40 High Mileage Motor Oil exceeds the toughest automotive standards for engine protection and performance in today’s higher mileage vehicles. … And it will surpass your expectations too.
Is Thicker oil better for high mileage cars?
High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. … Some mechanics recommend switching to a thicker (higher viscosity) oil — such as 10W-30 full synthetic oil instead of 5W-20 full synthetic — or using oil additives to stop leaks.8 mai 2017
Can I switch from 10w40 to 5w40?
Yes. 10w40 is thicker than 5w40, it will not lubricate all the parts that need lubricating from cold. You’d probably be better of leaving the old oil in there than swapping the correct (but old) oil for incorrect (new) oil.
Is it OK to mix 5w40 with 10w40?
As long as both oils have the same C-classification, or at least close -no problem in mixing different weights.1 sept. 2010
Can I put 5w 40 oil in my car?
5w40 is better for starting your engine at low temperatures as it flows more easily in this environment. When the engine is running and hot, the differences are negligible; 5w40 and 10w40 both have high viscosities and are equally effective in protecting against engine wear.13 mai 2020
