Can 5w30 be used instead of 10W40?

The difference is in the viscosity of each at different temperatures. The 5w30 oil will flow better at low temperatures than the 10w40 oil. This means that the 5w30 oil will protect the engine better at low temperatures, usually when the engine is just starting or during weather conditions such as winter.

Is 10W-40 better than 5w-40?

The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity). However, the main difference between these two engine types is that the 5W40 can work better than 10W40 in very cold places.

Is it better to use thicker oil in high-mileage engine?

High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. Some mechanics recommend switching to a thicker (higher viscosity) oil — such as 10W-30 full synthetic oil instead of 5W-20 full synthetic — or using oil additives to stop leaks.

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

10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.

When should I use 10W40 oil?

While both are low-temperature grade oils, 10W40 is thicker at high temperature; therefore, better to use in warm weather.

Is 5w30 thicker than 10W40?

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.

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.

Is 5w30 good for high mileage?

5W-30 motor oil is the top viscosity recommendation by automakers over the past four decades for use in many vehicle types. Furthermore, high-mileage 5W-30 motor oil is specially formulated for late model vehicles or newer vehicles with over 75,000 miles/120,000 kilometers.

Which oil is better 10W30 or 10W40?

10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.
