Yes, you can safely mix one brand of oil (e.g. Mobil 1) with a different brand (e.g. AMSOIL) or conventional oil with synthetic oil (in fact, that’s what a synthetic blend is). Most synthetics today are fully compatible with conventional oils and can safely be mixed.
What happens if you mix different brands of motor oil?
MYTH: Switching motor oil brands is harmful to my engine.
Switching brands is not harmful to your engine as long as you choose an oil marked with the API donut of the same level, e.g., API SN. Motor oil manufacturers must meet minimum industry standards for performance and compatibility of the API mark.
Can I top up engine oil with different brand?
You can add any engine oil as long as it has the right specifications — preferably with an official approval of the OEM (Original Equipment Manufacturer). Not the brand, but the specification and viscosity indicated in your car’s manual are your reference for using the right oil.
Can you mix different 5w30 oils?
Can you mix different 5w30 oils? Yes, you will be fine so along as the viscosity grade of the two oils are the same (e.g. 5W-30 and 5W-30). Never mix 5W-30 and say 10-40.
What happens if you put 5w20 instead of 5w30?
If you put in 5W-30 oil instead of 5W-20 when the latter is the grade suggested by your vehicle’s manufacturer, damage to internal engine parts can occur. Additionally, your engine may experience performance issues such as diminished fuel economy and horsepower.
Can I mix synthetic and regular oil?
The short answer is… yes. If you don’t have a choice, adding synthetic oil to regular oil can help you out in a pinch. … Since motor oils are generally made from the same ingredients (base oil and additives), they are typically compatible when mixed.
What happens if you use 10w30 instead of 5w30?
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.
Can I mix 5W-30 and 10w30?
Can you mix 5W30 and 10W30? The simple answer is YES; you can mix the two oils; not just because they have the same weight, but because it is safe to mix two different engine oils.
Is it good to top up engine oil?
Topping up your oil is typically not recommended unless the level is below the minimum mark. … If you do choose to top off your oil, you’ll need to use the viscosity and the quality level of oil recommended in your owner’s manual. To add oil, turn your vehicle off and wait for the engine to cool.
Can you mix 0w20 and 5w30?
Yes, just that. Pennzoil Platinum is a thin 30 or Valvoline Advanced also in 5w-30. Both syn oils. If you are in that part of NorCal where it’s truly -10 or more, consider M1 AFE 0w-30.
Can you put any oil in your car?
While it is not recommended to mix various brands of motor oil (such as Valvoline, Castrol, Total or Mobil 1), it will not cause any damage to your engine. What is far more important is to stick with the same oil viscosity as recommended by the car manufacturer.
