Are 5w20 and 5w30 interchangeable?
So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures. A majority of manufacturers are now producing engines that operate on 5w20 oil, to which it's important to stick to this viscosity and not substitute 5w30. via
Should I use 5w20 or 5w30?
The thicker 5W-30 should see a slight advantage when operating at higher temperatures, while the thinner 5W-20 oil should provide better engine protection at lower temperature levels and has the added benefit of slightly improving fuel efficiency. via
What can I use instead of 5w30?
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. via
What happens if you mix 5w20 with 5w30?
You can't mix between regular/synthetic blend/full synthetic but mixing weights, especially if they're by the same manufacturer, is no problem. via
What happens if you put the wrong oil in your car?
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. via
Is 5w30 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. via
Is 5w20 High mileage?
Protects for up to 20,000 miles between oil changes†
Mobil 1 Extended Performance High Mileage 5W-20 advanced full synthetic motor oil is designed to protect critical engine parts for up to 20,000 miles between oil changes† and help extend the life of vehicles with more than 75,000 miles. via
Why does Ford use 5w20 oil?
The main reason 5W-20 was specified for your engine is to increase the CAFE reported to the Federal Government. For model year 2001, the change to a 5W-20 oil will allow Ford and Honda's overall CAFE to increase by a very small amount, typically in the tenths of a mile per gallon range. via
Will it hurt to put 10w30 in a 5W20 engine?
Modern cars are designed to use lower viscosity oil ranges, so they can properly lubricate ( see attachment) Going from 5w-20 to 10w-30 should cause no harm for one oil change. But if you engine as designed for 5W-20, give it 5W-20. via
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. via
Can I mix synthetic and regular oil?
The short answer is… yes. If you don't have a choice, adding synthetic oil to regular oil can help you out in a pinch. Since motor oils are generally made from the same ingredients (base oil and additives), they are typically compatible when mixed. via
Is Thicker oil better for older engines?
Newer vehicles can utilize thinner oils for faster lubrication of new engine parts. In contrast, older, high-mileage engines benefit from thicker oils to prevent friction and oil loss. via
What happens if you mix different weight oils?
Mixing different oils will not improve the performance or efficiency of the engine in any way. The additives in synthetic oil may have limited or no effect at all when mixed with a regular engine oil. You can use 1 litre of 5W30 mixed with 5W40 and it will not cause any sort of ill effects to the engine. via
Can you mix different oil viscosities?
THE ANSWER IS NO!
Even if two different brands of oil have the same viscosity, you still should not be mixing them together. Technically, using a grade of oil that's recommended by your car manufacturer is correct. However, if you combine two different brands of motor oil, you could be at risk of damage. via
What happens if you put 0w20 instead of 5w30?
Pennzoil's 0W synthetic motor oils offer the same protection as SAE 5W and gives the additional benefits of faster flow at start-up, enables faster engine warm up and delivers better fuel economy. via
What happens if I use 15w40 instead of 5w30?
5w30 provides best cold start properties. Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine's crank. No it won't blow off,you will just wear your engine out quicker because the oil won't flow to the moving parts as quickly ! via
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. via

Is 5W-20 oil synthetic?
Mobil 1 5W-20 advanced full synthetic motor oil is designed to deliver outstanding engine protection, keep your engine running like new and protect critical engine parts for up to 10,000 miles between oil changes. via
Is 5W-20 oil conventional?
5W-20 – There's nothing conventional about it. High-quality petroleum base stocks. Low-temperature pump-ability—for faster start-ups and reduced engine wear in low temperatures. via
What are high mileage oils?
High-mileage oils have ingredients to take care of older engines, like conditioners, seal swells, antioxidants, detergents and wear or friction additives. Typically they use a viscosity modifier that is durable and won't lose viscosity very easily. These oils need to stay thicker longer to protect engine parts. via
What does SAE 5W-20 stand for?
The term 5W20 describes the SAE class according to which the engine oils were specified. They are multigrade oils with very good flow properties at low temperatures. 5W means that the oil is suitable for winter temperatures down to -35 °C. via
What's better 0W20 or 5W20?
0W-20 synthetic oil's range is between -40°C to 20°C while a 5W20 (5W20 synthetic oil) is from -35°C to 20°C. It is better to use 0W20 oil if you live in a place with very cold temperatures, such as Alaska or Maine. You cannot use either 0W20 or 5W20 in areas where temperatures exceed 20°C/68°F like Florida. via
What is the difference between 5W-20 and 5W 40 motor oil?
Whats the difference between 5W-20 and 5W-40 motor oil? - a higher grade (like the one you used = 40), means that the oil has more viscosity, and can lubricate in higher temperature, and is a bit thicker. - a lower grade (like the one on cap = 20), means less viscosity, lubricate in lower temperatures, a bit thinner. via
Will 5W30 hurt my 5W20 engine?
Using 5W30 oil for your vehicle will not blow out the engine. Your vehicle runs best at 5W20 and this is the type of oil that is recommended by the manufacturer; I always advise customers to use the type of oil that the manufacturer recommends. via
Will 10W40 hurt a 5W20 engine?
You can let it cool off enough so you do not burn yourself.. but keep it near hot does the best. And a 10W40 would invalidate your warranty... just so you know. In a 5W20 engine. You could use a 0W20 oil (I use 0W20 oil) in cold weather and it would be Ok by Ford. via
Can I mix 5W20 and 10w30?
It should be fine, considering the temps, and that the suggested oil viscosity is usually 5W-30, so two quarts of 5W-20 and three of 10W-30 probably come pretty close to some viscosity around 5W-30. via
Which oil is thicker 5w30 or 10w40?
A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine's moving parts more than the lower viscosity 5w-30 oil. via
What happens if you put thicker oil in your car?
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. via
What does the 30 mean in 5w30 oil?
How is 5w30 different from other oils? 5w30 motor oil has a winter viscosity grade of five, meaning it's less viscous (less thick) at very low temperatures compared to, say, 10w30. It has a hot viscosity grade of 30, which means it is less viscous at high temperatures than an oil such as 5w50. via
