Quick Answer: What Engine Oil?

How do I know what engine oil my car needs?

You will generally find the recommended car engine oil grade/viscosity & specification within your vehicle’s handbook, or you can use our engine oil lookup to make sure you’re getting the right oil.

Should I use 5w30 or 5w40?

The most significant difference between the two engine oils is the viscosity of these oils in hot temperatures. While 5w30 is much suitable to use in cold temperatures, the 5w40 is better for hot temperatures.

Which oil is best for car engine?

  • Shell Fully Synthetic Engine Oil for Cars. Purchase this car’s engine oil from Shell that comes in the 3.5 L quantity.
  • Castrol Full Synthetic Engine Oil.
  • Servo MGO 20W-40 Engine Oil.
  • Mobil Fully Synthetic Engine Oil.
  • Motul Engine Oil for Cars.

What type of oil is engine oil?

Most motor oils are made from a heavier, thicker petroleum hydrocarbon base stock derived from crude oil, with additives to improve certain properties. The bulk of a typical motor oil consists of hydrocarbons with between 18 and 34 carbon atoms per molecule.

Can I put 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.

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

Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so. Contrary to what some believe, adding synthetic oil to regular oil won’t harm the engine, but there’s also no benefit in doing so.

What happens if I use 5w40 instead of 5w30?

What would happen if I use 5w30 oil instead of 5w40 in my car engine? So long as the oil pump can produce enough pressure to get the oil flowing into all the important areas properly, there should be no problem. If the oil pressure light does not go on at idle you are likely not causing any damage.

Can I mix 5w30 and 5w40 oil?

You can use 1 litre of 5W30 mixed with 5W40 and it will not cause any sort of ill effects to the engine. In the long run, though, stick to using one type of oil to get the best performance out of your engine.

Is 5w30 thinner than 5w40?

The working viscosity of 5w30 is basically from 9.3 to 12.5mm2/s whereas the operating viscosity of 5w40 is 12.5 to 16.3mm2/s. That means 5w40 has larger viscosity than 5w30.

What does oil do in a car engine?

Motor oil provides lubrication to the many moving parts of an engine, which helps to avoid damage and keep your engine running smoothly. Each time your engine runs, by-products from combustion are collected in your engine oil.

Should I use thicker oil in a high mileage engine?

A: Yes. This is a practical method to improve oil pressure in an older, highmileage engine. The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well.

What do you need to change oil in a car?

In addition to oil, you‘ll need an oil filter, an oil-filter removal wrench, a wrench to remove the drain plug, a funnel, a drain pan and some gloves. You may also need to raise the car to gain access, in which case you‘ll need a floor jack and safety stands, or a pair of purpose-made steel ramps.

What is the thickest oil?

60 is the thickest oil in general use, but there are racing grades that go to 70. The SAE grades go from the extremely thin Winter 0W through to 70, (for different flows at 100°C for the non-W range). 60 is the thickest oil in general use, but there are racing grades that go to 70.

What is SAE 30 oil?

SAE 30 oil is a single-viscosity petroleum-based motor oil having an SAE standard kinematic viscosity of 30. It is recommended for use in temperate climate conditions with above freezing temperatures.

Can I use 5w30 instead of 5w20?

5W-30 and 5W-20 motor oil both feature the same winter rating. This means that both grades exhibit the same viscosity under cold conditions. You also risk engine damage when using 5W-30 instead of 5W-20, as the internal engine components are specifically designed to be used with 5W-20 motor oil.
