Can I put 5w40 instead of 10W40?

No, you can use 5w-40 anywhere a 10w-40 is recommended. At operating temperatures, both oils are 40wt and are equivalent. What matters most is the operating temp viscosity (the 2nd number). The first number (with a “w”) only applies to colder oil viscosity.

Can I use 5W-40 instead of 5W-30?

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 ambient temperatures of 50°C, as opposed to 30°C.

What happens to an engine if I use 10W-40 instead of 5W-30 manufacturer recommended )?

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. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

Can you mix 5w40 and 10W40?

Hello Derek, If you have drained the engine oil and plan on replacing it with the 5W-40, the small remainder of the 10W-40 will mix in with this new oil.

Is 5w 40 oil thicker than 5w30?

5w30 is engine oil that has lower viscosity 5 and higher viscosity 30. 5w40 oil is not thicker has it has a higher viscosity. Temperature. 5w30 has lower viscosity hence it is suitable to use in hot or lower temperatures.

Should I use 5w or 10W oil?

There is a small benefit of using a 10W instead of a 5W oil in that the 10W will normally have less viscosity improvers in it. Viscosity improvers help the oil behave “thicker” at higher temperatures, but they do not actually provide lubrication.

What is 10w-40 oil used 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 is the difference between 10W-40 and 5W 40 engine oil?

The main difference between the two oil types is that one is thinner than the other. The 5W40 is thinner than the 10W40 at lower temperatures. On the other hand, the 10W40 motor oils are thicker than the 5W40 oils for good reasons. This oil type works pretty well in lubricating engine parts during startup.

What is the difference between 10W-40 and 5W-30?

A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.
