Quick Answer: How Do You Know What Kind Of Oil Your 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.

What kind of oil is best for your car?

The Best Synthetic Oil

  • Mobil 1 120764 Synthetic Motor Oil 5W-30.
  • Valvoline 0W-20 SynPower Full Synthetic Motor Oil-5qt (813460)
  • Pennzoil 550046122 Platinum 5W-20 Full Synthetic Motor Oil.
  • Shell ROTELLA Full Synthetic Diesel Engine Oil.
  • Royal Purple High Performance Synthetic Motor Oil.

Does my car need synthetic oil?

Typically, high-performance vehicles will be more likely to require synthetic oil, as will vehicles that have a turbocharged or supercharged engine. However, if the automaker for your vehicle does not require synthetic oil for your engine, the oil choice is trickier — and there is no clear answer.

Is it better to use 5w30 or 10w30?

When to Use 10w30 vs 5w30

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.

Which oil is better 5w30 or 10w30?

A higher viscosity oil, such as 10w30, will flow slower at low temperatures compared to a lower viscosity oil like 5w30. A higher viscosity or thicker oil will seal better than a low viscosity oil. A thicker oil will also provide better lubrication of critical engine parts.

What is the best oil to use in the 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.

Is full synthetic oil worth it?

Why Synthetic Oil Is Worth the Extra Cost. Synthetic oil is more expensive than conventional oil but offers superior protection for your car’s engine. So if you can afford the extra cost, you should choose synthetic oil — and if your car requires it, you must use it.

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.

Can use 5w30 instead 5w20?

The key difference between 5W20 and 5W30 motor oil is that the former is thicker or less viscous. On the other hand, 5w30 motor oil is a suitable choice for hotter climates where thinner oils tend to break down under high temperatures.

Can I mix synthetic and regular oil?

The simple answer: Yes. There is no danger mixing synthetic and conventional motor oil; however, conventional oil will detract from the superior performance of synthetic oil and reduce its benefits. So, yes, you can safely mix synthetic and conventional oil.

Can you put synthetic oil in an older car?

Synthetic oil technology has improved over the years, and most cars on the road today should be able to use either synthetic or regular oil, so long as the proper weight is used. In fact, some new cars require synthetic oil. The seals in those engines may not be able to handle the additives in synthetic oil.

What are the disadvantages of synthetic oil?

Disadvantages of Synthetic Motor Oil

  1. Many of the synthetic oil blends reduce friction better than conventional motor oil.
  2. Synthetic oil does not hold lead in the suspension of the oil.
  3. Problems with racecar type engines using roller lifters.
  4. Synthetic oil has different disposal methods.
