What kind of car oil do I need?

The carmakers usually specify a 5W-20 or 5W-30 oil, particularly for lower temperatures, with a 10W-30 oil as optional, particularly for higher ambient temperatures. These three ratings cover just about every light-duty vehicle on the road. Even more important, though, is changing the oil and filter regularly.

Herein, how do I know what kind of oil my car needs?

There's no substitute for reading your owner's manual. It will list what type of oil the automaker recommends for your car. It may also recommend different oil depending on whether you live in a hot or cold climate. The most important thing is to use oil that's the right thickness, or viscosity, for your car's engine.

Subsequently, question is, can I use 10w30 instead of 5w30? The 10W30 and 5W30 both have different thicknesses in cold temperatures, and 10W30 is thicker than 5w30. So, it is best for vehicles running in cold climates to use the 5W30 since it is thinner than the 10w30. Low numbers indicate lower viscosity, meaning the oils are thinner.

Subsequently, question is, what type of engine oil should I use?

Types of Motor Oil

• Full synthetic oil is ideal for vehicles that demand peak level performance and high levels of lubrication.
• Synthetic blend oil offers the best of both worlds.
• Conventional oil is the most commonly used type of oil.
• High mileage oil is specifically designed for cars with more than 75,000 miles.

What are types of oil?

Car manufacturers usually specify 5W-20 or 5W-30 oil, though some require 10W-30. These three ratings cover just about every light-duty vehicle on the road, though this is changing as engines become more precise and fussy about specific types oil. Full-synthetic Oil: These oils are made for high-tech engines.

What happens if I put the wrong oil in my car?

Motor oil slip-ups. The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. Use only what the owner's manual specifies. Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so.

Should I use thicker oil in an older 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. The engine does not leak and I've never seen a whiff of blue smoke.

Is high mileage oil worth?

If an engine isn't burning or leaking oil, or if it uses, say, less than a quart over 6,000 miles or so, switching to high-mileage oil may not be worth the extra cost for you. High-mileage motor oil doesn't hurt and it could prevent leaks from starting.

Does my car need synthetic oil?

Check your owner's manual to determine whether you vehicle requires synthetic oil. Most newer cars require synthetic oil but older cars should run just fine with a conventional oil unless your car has over 75,000 miles on it, in which case a high-mileage oil is recommended.

Which oil is better 5w30 or 10w30?

5w30 is less viscous than 10w30. 5w30 is also the thinner engine oil of the two at lower temperatures. 5w30 is used for light-duty engines while 10w30 is used for engines which carry heavier loads. 10w30 provides sealing action in the engine due to the fact that it is thicker than 5w30 engine oil.

Is synthetic oil better for your engine?

Because synthetic oil is better on your engine and has fewer impurities, it can go longer than conventional oils or synthetic blends. Turbo engines and older cars may still require oil changes every 3,000 to 5,000 miles. Synthetic oil change intervals range 10,000-15,000 miles or once a year (whatever comes first).

Can I 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 synthetic oil better for diesel engines?

Western Turbo Diesel & Fuel Injection There are many advantages to using synthetic engine oil in your diesel engine. Synthetics have a much better flow rate in cold weather than conventional engine oils, allowing critical moving parts to be better lubricated on start up.

Is there a difference between motor oil and engine oil?

Motor oil is for your vehicle's engine. A couple of differences are the following: An engine oil is designed to deal with the products of combustion, whereas an automatic transmission fluid (ATF) does not see contaminants from fuel burning.

How long does full synthetic oil last?

Bell says that with synthetic oil and some manufacturers, intervals between oil changes can be much, much longer: "In some cases as much as 15,000 miles or one year." Some mechanics, though, say you should change your oil every 5,000 miles even with synthetic oil.

Can I use 5w30 instead of 5w20?

The key difference between 5W20 and 5W30 motor oil is that the former is thicker or less viscous. The more viscous motor oil is, the better it will be able to resist the heat and not break down. In this case, 5w30 oil will provide better overall engine protection than 5w20.

What does the W mean in oil?

The "w" in motor oil stands for winter. The first number in the oil classification refers to a cold weather viscosity. The lower this number is, the less viscous your oil will be at low temperatures. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil.

Who makes Toyota synthetic oil?

orenji Senior Member. Toyota 0W-20 for USA (and I assume also Canada) is currently manufactured by Mobil to Toyota's recipe, as far as I know. It's not the same as any of the various flavors of Mobil1. You are correct, Toyota Oil is Mobil 1 oil, but it a has different additive package to meet Toyota spec.

Will thicker oil damage my engine?

Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don't transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.

Is it OK to switch from 5w30 to 10w30?

The only difference between these two oils is cold flow ability: a 10w30 oil will move slower than a 5w30 oil during cold startups. At operating temperatures, both oils will have the same viscosity (30) and will flow and protect identically. If it will only be in the engine during the summer, use 10w30.

What happens if you put 10w30 in a 5w30 engine?

Your oil is a little thicker when cold. No damage will happen. The 5W and 10W defines how the oil will flow at 0 degrees. At operating temperature, there will be a completely insignificant difference between the two.
