What is 5w 50 oil used for?

A 5W-50 motor oil is suited for a broad range of applications including motorsport, classic/collector cars and extreme driving conditions like towing and high operating temperatures.

What happens if I use the wrong weight oil?

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.

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

In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to temperatures of 50°C, as opposed to 30°C.

The short answer:The numbers represent the viscosity of the oil and the W stands for WINTER. … In a 5W-30 for example, the number before the W describes the viscosity of the oil at low temperatures. The lower the number, the thinner the oil and the better the oil’s cold temperature/ cold start performance.

Can I mix 10w40 with 5w30?

As posted above, mixing 5w30 with 10w40 will give you an oil that performs somewhat better in the cold than 10w40, but less good cold than 5w30, and that has a viscosity a bit higher than 5w30 but a bit lower than 10w40.

Can I top off oil with different brand?

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.

Can the wrong oil cause smoke?

“Regardless of the vehicle manufacturer, we have noticed white smoke being emitted immediately after an engine oil change. … If the oil is not the correct type or viscosity, it could also bypass the rings on the piston or valve seals and end up in the combustion chamber.

Does it matter what 5w30 oil I use?

If your car takes 5w30 oil and you put 5w30 oil in it, it’ll be fine. Totally wrong, these days the spec compliance of an oil is often more important than the viscosity. Don’t put any 5w30 in, put the correct 5w30 in.
