Is 10w30 better for high mileage?

Both high mileage 5w30 and 10w30 engine oils have the same additives, the only difference is the viscosity at cold startups. Since both oils have the same operating temperature viscosity (30) and additives, they will perform exactly the same. However, 5w30 flows much better than 10w30 during cold starts.

What happens if I put 10w40 instead of 5w30?

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.

Is Thicker oil better for older engines?

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

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

Both can be used in all temperatures but the 5W30 performs better during cold temperatures and the 5W-40 works better in warm temperatures. Most enthusiasts will agree that 5W30 is the better due to it versatile application and better performance.

Can I switch from 5w40 to 5w30?

In most cases, if they recommend SAE 5W-40, then SAE 5W-30 may cause problems with wear or even engine damage. SAE 5W-40 will always be “Thin” enough at any temperature, but SAE 5W-30 may be too “Thin” at high temperatures.

Whats thicker 5w40 or 10w30?

Applications of 10W-40 Motor Oil Drivers commonly use 10W-40 motor oil in vehicles with higher mileage because the oil is thicker while the engine is hot; this helps lubricate older moving parts. This oil is meant to start up vehicles in winter climates that experience temperatures of 10 degrees Celsius.

What oil is thicker 5w30 or 10w30?

10w30 is thicker then 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.

Do high mileage cars need thicker oil?

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.

Is it OK to mix oil brands?

Even if two different brands of oil have the same viscosity, you still should not be mixing them together. … Technically, using a grade of oil that’s recommended by your car manufacturer is correct. However, if you combine two different brands of motor oil, you could be at risk of damage.

What does 5w40 mean?

5w40 engine oil has a winter viscosity grade of five, meaning it’s less viscous at very low temperatures, compared to, say, 10w40. It has a hot viscosity grade of 40, which means it is just as viscous as 10w40 at high temperatures but less viscous than oils such as 15w50. Why does the viscosity of engine oil matter?

Can I use 10w 40 instead of 5w40?

Aslong as its fully synthetic it will be fine. 5w – 40 will be better for colder conditions, 10w is thicker to start with thus doesnt get to places around the engine as quickly as 5w-40, but it all depends on temperature.
