What happens if you put 10w40 instead of 10w30?
A 10W30 engine oil will still be able to protect your engine, but it will thin out very fast that it may no longer be able to prevent the metallic moving parts from scraping against each other.
As such, you will have a much better chance of protecting your engine if you use a 10W40 in hot weather conditions..
When should I use 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.
Does 10w40 hurt 5w30 engine?
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.
Is 10w40 good for winter?
Yes, although they are both technically 10w oils, a 10w-40 is much thicker in cold conditions compared to a 10w-30.
Can I put 5 40 oil instead of 5w30?
In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to temperatures of 50°C, as opposed to 30°C.
Is 5w30 good for high mileage?
For example, a high mileage engine oil rated at 5W30 will flow better and has a superior viscosity at low temperatures when compared to an engine oil with a rating of 10W40. If you live in a cold environment, it is always best to go with a high mileage oil that has a lower SAE rating like 5W30.
Is 5w30 good for old cars?
In general thinner oils flow faster and lubricate better, and keep the engine parts cooler. using a thicker oil is asking for trouble. So if your original specification calls for 5W30, I wouldn’t change it. … It protects the engine due to lower levels of friction.
Will the wrong oil damage my engine?
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.
What happens if you put thicker oil in your car?
#4 – Poor Fuel Economy If you use too thick of a motor oil for the conditions, your fuel mileage will likely suffer. This is because the thicker oil increases resistance on moving parts such as pistons. While your engine will be protected, it will be at the expense of more frequent trips to the gas station.
Does thicker oil help with leaks?
As an engine heats up, the oil thins, becoming more susceptible to leaks through faulty gaskets. Draining the oil from your vehicle and replacing it with a thicker weight or synthetic oil can help to prevent oil from leaking through some of the smaller breaks in the gasket seals.
Is 0w20 better than 5w30?
It readily means that the 0 oil will flow well and better at a cold temperature more than 5W-30 oils even while maintaining the same viscosity. … Temperatures and certain climate conditions affect the use of 0W-20 over the 5W-30 engine oil.
Is Thicker oil better for high mileage cars?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well.
Can I use 10w 40 instead of 5w30?
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.
Which is better 5w30 or 10w40?
The main difference between the 5w30 and 10w40 is the viscosity difference at different temperatures. … The one, 5w30, will be able to flow better when the temperatures are low than the 10w40. So at a lower temperature, the 5w30 oil will be the best to protect the engine.
What happens if I put the wrong oil in my car?
You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.
