What's the difference between 5w20 and 5w30 oil?

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.

Is it OK to use 5w30 instead of 5w20?

While both 5W20 and 5W30 motor oils are suitable for high mileage engines, the best viscosity type for your vehicle depends on how the manufacturer designed the engine. Using 5W30 when it is advised that you use 5W20 can result in your vehicle not getting good fuel economy.

Is 5W-20 or 5W-30 better?

5w20 is an engine oil type characterized by its winter rating of 5 and an oil weight of 20 in warmer conditions. It is less viscous compared to 5w30. 5w30 has the same viscosity rating of 5 during winter but an oil weight of 30 during hotter conditions hence it is thicker.

Is 5w20 good for winter?

5W20 motor oil is another low-temperature grade typically recommended for winter use, with a 10W-30 as an alternative for higher temperatures. This oil type is common because it provides the best fuel economy, saves fuel consumption, and has fewer exhaust emissions.

Is 5W 20 good for hot weather?

Is 5w 20 Good For Hot Weather? Oils of this type tend to cover the range of possible temperatures, with a 5W-20 oil more suited to colder climates and a 5W-30 oil more appropriate for warmer climates. It is likely that either of these will work just fine in an engine, regardless of the prevailing temperature.

5w20 or 5w30? Which do I run and why. Is 5w20 a hoax for fuel milage?

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.

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.

What can I use instead of 5w20?

10w30 and 5w20 engine oils have similar SAE ratings, which means that they will perform similarly at operating or high temperatures. The number 30 indicates the viscosity of the oil at high temperatures, as stated before. 10w30 tends to get thicker in cold weather which makes 5w20 better suited for these environments.

Can you mix 5w30 and 5/20 oil?

Yes, you can mix 5W20 and 5W30 oil. However, your engine MUST support it. Both oils should be of the same brand to prevent engine damage and should also be of a similar API service level.

What is 5W-20 oil good for?

What Is 5W-20 Oil Good For? As 5W-20 is a low viscosity oil, it's best suited for cars that drive a lot in low temperatures and colder climates. It's ideally recommended for light-duty petrol and gasoline engines, and can help with engine deposits and wear and tear problems.

Can I use 5w30 instead of 5w20 in my Toyota?

Synthetic oil with a viscosity rating of 0W-20 is specified for your vehicle. 5W-20 is acceptable as well. 5W-30 will not harm your engine. Use of 5W-30 might add some additional cost in terms of reduced fuel economy due to use of the higher viscosity oil.

Why can't you go back to regular oil after synthetic?

Myth: Once you switch to synthetic oil, you can never switch back. This is one of the most persistent myths about synthetic oil—and completely untrue. You can switch back and forth at any time. In fact, synthetic blends are simply a mixture of synthetic and conventional oils.

Should I use thicker oil in a high mileage engine?

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 mix synthetic and regular oil?

So, in the end, conventional and synthetic oils are comprised of the same, compatible components – it's just that the components in synthetics are much higher quality. While you can safely mix synthetic and conventional oils, you're doing nothing more than diluting the performance of the synthetic oil.

Is 5w30 good for summer?

When should I use 5w30 oil? You should always use the oil recommended by your vehicle's manufacturer. However, 5w30 oil can function in temperatures as low as -30ºC and as high as 40ºC, making it an ideal choice if you drive your car in a place with relatively high seasonal temperature variations.

How long does 5W 30 oil last?

Mobil 1™ Extended Performance High Mileage 5W-30

Provides 20,000 miles of protection for vehicles with more than 75,000 miles – guaranteed.

Is 5w30 good for winter?

An example is 5W30—the “W” stands for winter and the oil's cold weather rating. The lower the W number, the better the oil will perform in colder temperatures. Typically, a 5W oil is recommended for winter use, but synthetic oils can be formulated to flow even more easily when cold.

What oil is best for old engines?

Is 5w30 thicker than 5w20?

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.

What oil is best for high mileage cars?

At what mileage should you switch to synthetic oil?

It's recommended that you change synthetic oil every 7,500 – 15,000 miles, depending on the vehicle and the brand of synthetic oil used. To ensure you're changing your oil at the proper intervals, always check your owners manual for more information.

What is the disadvantage of synthetic oil?

Probably the most glaring downside of synthetic oil is the cost. The price of synthetic oil is around two to four times the price of conventional oil. Synthetics may be more prone to additives precipitation during cold storage conditions.

How long is synthetic oil good for?

So, how long does synthetic oil last? On average, synthetic oil lasts about 6 months to 1 year or 7,500-10,000 miles before needing replacement. However, this is only an approximation and is subject to change based on several factors such as oil brand, age of the vehicle, and driving conditions.

Is 5W-30 oil synthetic?

Mobil 1™ 5W-30 is an advanced full synthetic motor oil designed to keep your engine running like new by providing exceptional wear protection, cleaning power and overall performance. Mobil 1 5W-30 meets or exceeds the requirements of the industry's toughest standards and outperforms our conventional oils.

What does 5W-30 mean?

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.
