When Should I Use 10w40 Oil?

Is 10w40 good for summer?

However, if you live in warmer or hotter regions, you’d definitely want to grab the 10W40 engine oil.

This is especially important during hot summer days when the scorching heat of the sun can really amplify the heat generated by your engine..

What happens if you put thicker oil in your car?

The higher the number, the thicker the oil. Thicker oil protects engine parts better than thinner oil under tough conditions. For instance, if you’re driving in Arizona in the middle of summer, a 20W-50 motor oil would protect your engine better than a 5w-20 viscosity.

What happens if you put wrong oil in car?

You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.

Does thicker oil protect?

Within reason, thicker oil maintains a better lubricant film between moving parts. Some have even used thicker oil in a leaky engine to prevent oil from seeping out. But really, thicker oil is not good for your engine. Not when “thicker” means higher viscosity than the manufacturer recommends.

Is it OK to use 10w40 instead of 5w30?

One must use the oil specified by the manufacturer. … If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

When should I use 10w 30 oil?

At operating temperatures, both oils will have the same viscosity (30) and will flow and protect identically. If the oil will be in the engine during winter and you live in a place where it gets cold during these months, use 5w30 oil. If it will only be in the engine during the summer, use 10w30.

What oil is best for high mileage?

Valvoline High Mileage with MaxLife Technology. … Castrol Edge High Mileage. … Mobil 1 High Mileage. … AmazonBasics High Mileage Motor Oil. … Pennzoil High Mileage Motor Oil. … Lucas Oil High Mileage Oil Stabilizer. … Royal Purple HMX High Mileage Synthetic Motor Oil.

Which oil is thicker 5w40 or 10w40?

The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity). … On the other hand, the 10W40 motor oils are thicker than the 5W40 oils for good reasons.

Do you use thicker oil in winter?

Thin oils that are less prone to thickening in low temperatures will help you start your engine more quickly in winter while thick oils that are less prone to thinning in hot temperatures will help your engine perform better in summer.

What does 10w 30 oil 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 labeled 5W30, which has a thinner viscosity when the engine is cold at 5W.

What is 20w 50 oil used for?

SAE 20w-50 Oil – Conventional & High Mileage A SAE 20W-50 motor oil is typically used in older vehicles or in particularly warm climates. Castrol GTX 20W-50 has been specially formulated to help extend the life of your engine by keeping it free from sludge, even when operating in extremely high temperatures.

Will 10w40 hurt a 5w20 engine?

In a 5W20 engine. You could use a 0W20 oil (I use 0W20 oil) in cold weather and it would be Ok by Ford. (they will not say it is good, but they will still honor the warranty..) But 10W40 is way off, and I bet they would be not so happy over any engine problems if they found 10W40 in a failed engine.

What happens if I put 10w40 instead of 5w40?

10w40 is thicker than 5w40, ONLY when cold. At operating temperature it is exactly the same. … Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures. There is no need to use a 5w-40 if the vehicle only requires 10w-40.

What oil is thicker than 10w40?

The difference between 10w30 and 10w40 is the thickness of the oil at operating/high temperatures, at which 10w40 is thicker than 10w30.

What is 10w 40 oil used for?

The synthetic 10W-40 flows easily and still maintains enough viscosity to protect piston skirts and bearings when it gets hot. The improved temperature stability of synthetics makes them a better choice for race engines and serious high-performance engines.

Is 10w40 good for high mileage?

The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well. As long as you’re not hearing knocking or serious mechanical noises from the engine, the heavier oil should buy you many more miles of service from your vehicle.

Is 10w40 good for winter?

Yes, although they are both technically 10w oils, a 10w-40 is much thicker in cold conditions compared to a 10w-30.

Is 20w50 good for high mileage?

Considerations. The viscosity level of engine oil 20W50 is geared toward racing engines, as opposed to high-mileage engines, that run extremely hot and need heavy load operation. … Since its viscosity is so great, it can drag down the functioning of the crankshaft, resulting in less horsepower.
