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.Jul 5, 2015
Should I use 5W30 or 10w30?
5w30 provides better lubrication compared to 10w30. It is best suited for private vehicles and light-duty diesel and petrol engines, while 10w30 is more suitable for commercial vehicles and other cars with heavy load engines.Oct 2, 2021
When should I switch from 5W-30 to 10w30?
The oils only differ in cold weather viscosity. If you never see temperatures below zero F then either 5W30 or 10W30 is fine. If winter temperatures are regularly below 0 degrees F then 5W30 is what you should run and you can run it year round if the 30 weight is good according to your owner's manual.
Is 5W-30 or 10w30 better for winter?
10w30, the thinner 5w30 will circulate quicker, and flow through bearing tolerances better during an engine startup in the winter or colder climates. The “w” behind the five and the 10 indicates that those are the viscosities in colder or winter temperatures.
Is 5W-30 good for high mileage?
Amazon Basics Full Synthetic is the best 5w30 oil for high mileage vehicles. This oil should only be used on vehicles exceeding 75,000 miles. This motor oil is formulated for longer drain intervals. It helps in preventing a build-up on drain intervals and preventing rust and corrosion.Oct 26, 2021
What is difference between 5W-30 and 10w30?
10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.Oct 2, 2021
Is it okay to use 10W40 instead of 5W-30?
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.Oct 21, 2017
When should I use 10W40 oil?
While both are low-temperature grade oils, 10W40 is thicker at high temperature; therefore, better to use in warm weather.
Is 10W40 good for high mileage?
Mobil 1 High Mileage 10W-40 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils†), including: Cars.
Does the type of engine oil make a difference?
Some additives contain different formulations to affect certain parts of the engine differently than other additives. MYTH: All brands of motor oil basically are the same. That's false. Base oils, additives, etc., can be different from one brand to the next.
What happens if you use the wrong engine oil?
Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.
Is it OK to top up engine oil with different brand?
You can add any engine oil as long as it has the right specifications — preferably with an official approval of the OEM (Original Equipment Manufacturer). Not the brand, but the specification and viscosity indicated in your car's manual are your reference for using the right oil.
