Is it OK to put 10W40 in a 10W30?

Mixing 10W30 with 10W40 Some say that mixing them is fine as long as you don’t live in freezing weather. Even if you put together synthetic and conventional blends of these motor oils, they show no harm to your vehicle.

Which oil is thicker 5w30 or 10W40?

5w30 is less viscous while 10w40 is more viscous. The 5w30 has a viscosity of 30 at high temperature while a 10w40 has a 40 viscosity at high temperatures. When at high temperatures, the 5w30 oil becomes thinner than the 10w40 oil since 30 is lower as compared to 40.

Should I use thicker oil in a 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.

Which oil is thicker 5w30 or 10W30?

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 oil offers better lubrication of motor and engine parts.

What happens if you 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?

Newer vehicles can utilize thinner oils for faster lubrication of new engine parts. In contrast, older, high-mileage engines benefit from thicker oils to prevent friction and oil loss.

Is synthetic oil better for high mileage cars?

Myth: Full synthetic oil is not good for high mileage cars or older vehicles. The myth is rooted in the idea that synthetic oil is “slipperier”—lower in viscosity, or not as compatible with seals and will therefore leak or leak more in places conventional oil might not. Again, completely untrue.

Is full synthetic oil worth it?

Is synthetic oil better for my engine than conventional oil? Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can’t compete with the overall engine performance and protection provided by synthetics.

What are the disadvantages of synthetic oil?

The main disadvantage of synthetic oil is the price. Manufacturing synthetic oil requires a far more involved process. Because of this, the price of synthetic oil is nearly four times the price of petroleum-based oil. Using a synthetic oil in a car change could cost you $80 versus $20 of a petroleum-based oil.
