What happens if I mix oil weights in my car?
It is always advisable to not mix motor oil brands, however, different viscosity grades of the same brand motor oil are compatible. Be aware that mixing viscosity grades will turn out a product that is different in viscosity than either what was originally in the engine or what was added.”
What happens if I use 10w30 instead of 5W-30?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.
What happens if you put 10w40 instead of 5W-30?
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 5W30 and 5w40 oil?
Because generally, the answer is yes. Several viscosity grades are compatible and possible to mix, especially when you are low in oil. It won’t cause any adverse effect on your engine. However, you should make sure that they are under one motor oil brand.
Can you put 10W oil in a 5W car?
If they originally recommended 10W-30, they you can use 5W-30 or a mixture. If they originally recommended 5W-30, your mixture will not pump as well at very cold temperatures.
Should I use heavier weight oil high mileage car?
For an older, high-mileage passenger car, it is recommended to switch to a thicker viscosity oil, such as 10W-30, when approaching and passing 100,000 miles, to lubricate the engine well for preservation.
Is it OK to mix 5w and 10W oil?
I often get asked if you can mix 5W-30 with 10W-30. Your engine would prefer that they be of the same formula, but it will not hurt even they are different brands. There is nothing wrong with mixing oils of two different viscosities, but it is not the optimum condition.
