Can I use 10w30 instead of 5w30?

Performance. Both 5w30 and 10w30 engine oils have a similar SAE rating, meaning that they will perform the same at high or operating temperatures. The digits 30 indicates the viscosity of the oils when in high temperatures. 10w30, however, will thicken more when in a cold climate.

Is there a big difference between 5w30 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.

Which oil is better 5w30 or 10w30?

5W-30 multi grade oil is ideal for private vehicles and light-duty petrol and diesel engines. It also provides a better cold temperature start than 10W-30 oil. On the other hand, the slightly thicker oil,10W-30, provides better lubrication for commercial vehicles and heavy-load engine cars.

Can I use 10w30 instead of 5w30 Reddit?

It will be fine.

Can you put 10w30 in a 5w20 engine?

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.

What does 10w30 mean? 'Engine Oil Explained'

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's the difference between 10W 30 and 5W 20?

Main Differences Between 5w20 and 10w30

5w20 is thinner at lower temperatures, whereas 10w30 is thicker at lower temperatures. 5w20 is better for cold-weather starting, whereas 10w30 is better for sealing action. Light duty petrol and diesel engines use 5w20, whereas large weight carrying engines need 10w30.

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 10w30 good for winter?

10W30 vs 10W40 Oil FAQs

10W-30 motor oil is recommended for ambient temperatures not exceeding -30°C/-22°F in the winter or 35°C/95°F in the summer. This is a great motor oil to use if you live in Canada or cooler U.S. states. Colder regions would require 5W-20, while hotter regions may call for 10W-40.

What happens if I put the wrong oil in my 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.

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.

Will 10w40 hurt a 5w30 engine?

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.

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 use 10w30 instead of 5w30 in snowblower?

The main difference between 10w30 and 5w30 oil is their viscosity. The heavier the oil, the more challenging it becomes for the snowblower to use it. The 5w30 oil is lighter and best suited for use in winter or areas where frigid weather is constant. Still, 10w30 can be used in a snowblower instead of the 5w30 oil.

What does the W in 10w30 oil stand for?

The “W” that you see on oil labels stands for the word "Winter" because this portion of the label shows the viscosity level of oil when an engine is cold. Motor oil that is thinner can flow more easily and faster. This is important because when you start a cold engine, the oil needs to lubricate the equipment quickly.

Is it OK to mix different engine oils?

WHAT ABOUT MIXING ENGINE OIL BRANDS? Yes. It won't harm your engine to mix, for example, Quaker State^® motor oil with Pennzoil, as long as the oil you use is the weight (or viscosity) recommended in your vehicle owner's manual.

Is it OK to mix oil weights?

The truth is simple: don't mix two different oils that have different weights (viscosities). Viscosity Grades might sound pretty scientific, but the simple fact is that this is what keeps your engine running smoothly.

Is it OK to mix engine oil weights?

Can oils of different grades be mixed? The good news is that mixing different types of oil it will not harm your engine in any way in the short run. Most synthetic and semi-synthetic engine oils are based on regular oil and are compatible.

Will thicker oil damage my engine?

Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.

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 I put 10w40 instead of 5w20?

Lose a little gas. mileage and lubrication is not as good plus it puts more strain on the oil pump. Never go thicker than a 5w30 and that would be more for an older higher mileage engine in warmer climates. So go change it back to 5w20.

What oil is best for old engines?

Why does engine oil turn black quickly?

What Causes Motor Oil To Turn Black? Thick, black, or very dark motor oil usually indicates that your oil has been exposed to dirt or dust contaminants that lead to a soot build-up. Direct injection gasoline engines produce soot over time that causes standard motor oil to turn black and thick.

What is best oil for high mileage cars?

Does engine oil get thicker or thinner with age?

Does Oil Get Thicker Or Thinner Over Time? The oil becomes thinner as it heats up, so it is less dense. If it cools down, it could become thicker. If your engine runs at operating temperature, you need 30 pounds of oil.
