Should I use 10W40 in summer?

High Operating Temperature Or Warm Weather

10W30 oil and 10W40 perform the same at cold temperature startups. However, 10W-40 engine oil is more viscous in hotter climates and has a better temperature spectrum.

Is 10W40 good for summer?

They are both available in pure conventional form or as high-quality synthetic grades. Either 10W30 or 10W40 for summer use is fine; however, 10W-40 motor oil will better protect your engine.

Is 5W or 10W better for summer?

While some car manufacturers still advocate the use of 10W-30 (or even 10W-40) as an appropriate engine oil option for summer use, it is completely unnecessary. Today's 5W-30 motor oils provide consistent protection at both extremes of the temperature spectrum.

What is 10W-40 Good 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.

What oil is best for summer driving?

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.

The importance of choosing the right engine oil quality and viscosity for your car or truck - VOTD

Can I use 10W-40 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 thicker motor oil better in hot weather?

Thicker oil in the winter would clog the pumps and fail to lubricate them properly. The best motor oil for hot weather is a thicker grade oil to combat the thinning effects of the heat. In the summer, you need a motor oil that will maintain just the right amount of thickness.

When should I use 10W40 oil?

So, if you drive in a warm climate — especially more than 32°C (90°F) — or have an engine that runs hotter than others, 10W-40 oil viscosity is a good option. This higher viscosity oil is designed for hotter temperatures and can handle the added heat stress from the environment.

Is 10W-40 oil OK for petrol engine?

It's guaranteed to be safe to use in both petrol and diesel engines which require 10W-40 fuel, and quality is assured thanks to our superior testing and development process. 10W-40 oil is commonly used in diesel engines, as well for motorcycles and older cars that have a history of oil leaks.

Is 10W40 good for high mileage?

Designed for high mileage vehicles

Mobil 1 High Mileage 10W-40 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils^†), including: Cars. Trucks.

Is 10w40 better than 5w30?

The 5w30 oil will flow better at low temperatures than the 10w40 oil. This means that the 5w30 oil will protect the engine better at low temperatures, usually when the engine is just starting or during weather conditions such as winter.

Can I put 10w40 instead of 10w30?

The short answer is yes. Because both oils are formulated to give the same performance, it will be safe for you to use either oil. Some differences between the two oils include viscosity and base oil.

Should I use different oil in summer?

Even though there's no need to swap oil grades in the summer, you should still invest in regular oil changes. Fresh, clean oil optimizes your vehicle's performance by properly lubricating engine parts and keeping the engine healthy—no matter the season.

Which engine oil is best for heat?

Mobil 1 advanced synthetic motor oil provides outstanding high-temperature performance and is proven to protect at engine temperatures up to 500 degrees Fahrenheit.

Is 10W40 fully synthetic?

Semi-synthetic oils such as 10W40 have long been the standard. Their base is refined crude oil, which is then blended with additives.

Is 5w40 good for summer?

5w30 oil is designed to operate at temperatures as low as -25°C, but is also a great choice for warmer climates that reach up to 25°C. In general, 5w30 is a great multi-grade oil for different temperature specters.

How long does 10w40 oil last?

Simply put, the shelf life of conventional motor or "lube" oil is up to five years. It's not something that goes bad in a couple of months.

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.

What does 10W-40 stand for?

10W-40 10W-40 is the engine oil which offers a 10 weight performance in the cold starting temperature. On the other hand, it provides a 40 weight performance at the normal operating temperature of the engine.

What is 10W 40 engine oil?

10W – 40 is used to describe the oil's thickness. “W” stands for winter. The number before the “W” signifies the viscosity of an oil at low temperatures – for example before you start your engine. The number following the “W” indicates its viscosity at normal operating temperatures when the engine is running.

Is 10W50 better than 10w40?

At 100ºC, the 10W50 has a viscosity of 18.1cS, the 10W40 is at 13.1cS. What this means is, at low temperature, they perform similarly, but at operating temperature, the 10W50 has better protection (higher film strength) than the 10W40.

Is higher viscosity oil better for hot weather?

In general, warm weather calls for thicker oils since they start at a higher viscosity and don't become too thin when the engine heats up further.

Is Thicker oil better for high mileage cars?

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.

Will the wrong oil damage my engine?

Cause damage to engine life

The wrong engine oil can cause engine damage because it does not properly lubricate its components. This will lead to metal-on-metal contact since the moving parts are not being lubricated. Friction quickly follows, causing engine parts to wear.
