Quick Answer

Quick Answer Can I put 10w30 instead of 5W-30?

The answer is yes. You can use 10w30 instead of 5w30 oil since both meet the SAE standard for viscosity at operating temperature. Generally, the viscosity difference between the two is neglectable.

Is there a big difference between 5W-30 and 10w30?

Both the oils have similar viscosity at 100 degrees Celsius but 5w30 grade oil will thicken less than 10w30 grade oil in cold climate. This means 5w30 grade oil will flow effectively in low temperatures, whereas 10w30 oil will flow effectively in high temperatures because of the smaller temperature window.

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.

Should I use thicker oil in an older engine?

Older engines use more oil, but it gives them a better fuel economy. Older engines with more than 75,000 miles on them require a thicker oil that will lubricate their critical engine parts and prevent oil leaks, sludge, and deposits from forming.

Is 10W40 thicker than 10W30?

10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.

Is 10W30 better for high mileage?

10W-30 motor oil makes for a decent high-mileage oil. It gives a better fuel economy while reducing the oil consumption for older engines. Older engines with more than 75,000 miles on them require a thicker oil that will properly lubricate their critical engine parts and prevent oil leaks, sludge, and deposits.

What is thicker than 10W30?

The quick answer is 10W40 is a thicker engine oil than 10W30 at higher temperatures. Both have almost the same characteristics, and the only difference is the oil viscosity.

Can you put 10W40 in a 10W30 engine?

Mixing 10W30 with 10W40

Some say that mixing them is fine as long as you don’t live in freezing weather. Even if you put together synthetic and conventional blends of these motor oils, they show no harm to your vehicle. However, this is true only if you mix in a quart of the other type to your usual engine oil.

Can I mix 10W30 and 5w30?

Adding 10W30 to your current mix is safe, and will not cause your engine to run any worse. But keep in mind that 10W30 has more density than 5W30. These two motor oils are very similar in viscosity
hence, they might mix perfectly in your engine. Therefore, you can mix 5W30 with 10W30 with no ill effects whatsoever.

Is 5w30 thinner than 10w30?

Both oils have lower viscosity at temperatures which measure the resistance of the oil to flow. However, 5w30 is much thinner compared to 10w30. 5w30 engine oils will, therefore, be able to protect the inner components of the engine faster than the 10w30 due to its low viscosity.

Is 10w30 good for summer?

As a general rule, you’ll get the best protection in the summer when you use a slightly thicker grade of oil, such as a 10W30 instead of a 5W30. Engines need a thicker oil in the summer months because of the summer heat and its effects on thinning the oil out.

Is 30 weight oil the same as 10w30?

The short answer to this is no, 10W-30 oil is not the same as SAE 30. The difference between 10W30 multi – grade and straight grade oil is that it has been formulated to provide a 10W viscosity at very low temperatures to aid in cold-cranking in heavy engines.

Is it safe 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.

Is 10W oil better than 5W?

A quick lesson in motor oil states that a regular engine needs oil that flows under the prevailing weather or running conditions. A 10W or 5W is the index for how easily the oil flows in winter (hence the W). A 10W oil thickens more than a 5W.

What oil is recommended for high mileage vehicles?

High mileage oil is designed for vehicles with more than 75,000 miles. Such oil features additives that help protect seals. This leads to less leakage and oil burn-off, which can be common in older cars. If your vehicle is high-mileage and high performance, it’s suggested that you go with this type of synthetic oil.

What does 10w30 stand for?

The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold, and 30 when the engine is hot. This is different than an oil labelled 5W30, which has a thinner viscosity when the engine is cold at 5W.

Is 10w30 good for winter?

Can I Use 10w30 In Winter? The 10W flow is good in cold weather, so it protects the engine at start up, but it is too thin for use in the summer when the engine is at full power. The recommended oil for summer use is a 30 grade oil that is thick enough to protect against heat.

Is 5w30 thicker than 10w40?

The 5w30 oil is much thinner than the 10w40 oil and on the other hand, the 10w40 oil is much thicker than the 5w30 oil. The viscosity of 5w30 at low temperatures is 5 whereas the viscosity of 10w40 at low temperatures is 10.

When should I use 10w30 oil?

However, the 10W–30 oil will be thicker when it is cold. As per API recommendations (1) for car engines, you can use 10W–30 oil if the maximum expected outside temperature is above -18°C (0°F). If you are living in an area where the outside temperature can go below zero
It is better to use 5W–30.

What cars use 10W 30 oil?

In addition to high-performance turbocharged, supercharged, multi-valve fuel injected engines found in passenger cars, SUVs, light vans, and light trucks, Mobil 1 10W-30 is recommended by ExxonMobil for all types of modern gasoline-powered vehicles.

What temperature is 10w30 oil good for?

Both 5w30 and 10w30 are multi-grade products. This means they are designed to perform at both cold starting temperatures and normal operation temperatures of 210° F without sacrificing performance.

What engine oil is thicker?

SAE50 is higher viscosity (thicker) than SAE40, and so on. Straight-weight oils come in a wide range of viscosities. But your car operates (ostensibly) in a wide range of temperatures. When your engine is running at operating temperature, it does not matter too much if it is summer or winter.

What happens if I mix 10W40 and 10W30?

Mixing 10W30 with 10W40 Some people say mixing them is fine as long as you don’t live in freezing weather. The motor oils in these blends are not harmful to your vehicle, even if they are mixed with synthetic oils.

Which is better 10W30 or 20w40?

20w40 is thicker at high temperatures than 10w30 It is desirable for lubrication at operating temperatures to be high. 20w40 is better than 10w30 at normal operating conditions.

What is 10W 40 oil used for?

This oil weight is commonly used in diesel engines or in a smaller motorcycle engine too. The 10W-40 oil viscosity also often serves as an alternative for older engines with burning or oil leaking issues. Why is that? The 10W-40 engine oil has a thicker viscosity than, say, 10W-30 oil when the car engine is hot.

Is it OK to put 10w30 in a 5w20?

Notwithstanding the recommendations of the car manufacturer, mixing 10w30 and 5w20 will not cause any sort of harm to the engine. However, a few drivers claim that it is safer to combine two multi-grade or straight weight oils, rather than mixing multi-grade with straight weight oils.

Can I use 10w30 instead of 5w30 Reddit?

It will be fine. You will not notice any difference in gas mileage or performance between those 2. This is not true. The viscosity does not change the physical size of oil.
