Can I mix different viscosity oils?

yes you can mix same brand and type oils with different viscosity and it will be fine as long as you don't mix them 50/50. If you mix 200 ml of oil with the rest of oil needed for your engine you will be totally fine.

What happens if you mix oil viscosity?

Oils are also made available with different grade ratings that determine the viscosity and its ability to perform under varying weather conditions. Can oils of different grades be mixed? The good news is that mixing different types of oil it will not harm your engine in any way in the short run.

Can you mix oil of the same viscosity?

THE ANSWER IS NO!

Even if two different brands of oil have the same viscosity, you still should not be mixing them together.

Is it OK to use different viscosity oils?

It's best to use the oil viscosity recommended in the owner's manual, but using a slightly thinner or thicker oil (lighter or heavier viscosity) generally poses no long-term harm.

Can you mix oils of the same weight?

They're all pretty much made by the same companies in the same assembly lines anyways. Don't mix weights or synthetic and non synthetic. You'll be okay.

Will Mixing 10 Motor Oils Damage an Engine? Let's find out!

Can I top up oil with different oil?

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 5w40 with 15w40?

Mixing a dino with a syn, a syn with a dino, a 5W-40 with a 15W-40, and so on is fine. You aren't going to get an additive clash, the different base stock of x brand of oil won't sponteously combust with the other x brand of oil that you are blending it with and make your engine throw a rod.

Can you mix 10W 30 and 10W 40?

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. However, this is true only if you mix in a quart of the other type to your usual engine oil.

What happens if you put 10W40 instead of 5w30?

Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

Can you mix 5w30 and 0w20?

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.

Is mixing oil bad?

Mixing different types can destabilize your motor oil, reducing its efficiency and affecting your engine's performance. The smartest choice is to stick with the oil type and oil change intervals recommended by your car's manufacturer and visit your local car care experts for affordable services.

Can you mix 5w20 and 10w30?

Notwithstanding the recommendations of the car manufacturer, mixing 10w30 and 5w20 will not cause any sort of harm to the engine. However, a few drivers claim that it is safer to combine two multi-grade or straight weight oils, rather than mixing multi-grade with straight weight oils.

Can I mix monograde and multigrade oil?

Due to the different properties of monograde and multigrade oil, we recommend that you do not mix the oils. Although mixing is possible, it makes no sense, as the oils drastically change their initial properties and viscosity, which can cause problems in the engine or transmission.

Can I mix 0w40 with 5w30?

Can I Mix 0W-40 With 5W-30 Engine Oil? Yes, if your car manufacturer approves it. If not, you should only use the approved oil. 0W-40 and 5W-30 oils can be combined because 5W-30 is thicker oil than 0W-40, and the extra, lower viscosity will make the start-up oil flow easy and efficient.

Can you mix 15w40 with 10w30?

you can mix the two without a problem, for Wisconsin, the 15w 40 would be a better oil in the summer and 10w 30 would be a better oil for the winter, if you drive the car in the winter! I have Rotella 15w40 weight oil in my LT-1 now and I just found a place that sells 10w30 which would be a better choice.

Can you mix 5w40 and 10W40?

If you have drained the engine oil and plan on replacing it with the 5W-40, the small remainder of the 10W-40 will mix in with this new oil.

Will thicker oil damage my engine?

Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.

Is it OK to put 10w30 in a 5w30?

Can I Mix 10w30 and 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.

What oil is heavier 10w30 or 10W40?

The quick answer is 10W40 is a thicker engine oil than 10W30 at higher temperatures. Both have almost the same characteristics, and the only difference is the oil viscosity.

Can I use 10W50 instead of 10W40?

In short, you can use 10W50 if your vehicle is specified with a 10W40 grade, at the expense of a little less power and mariginally lower fuel efficiency, but using the 10W40 on a vehicle for which 10W50 is recommended, will cause faster wear.

Is 5w30 thicker than 10w30?

Both the oils have similar viscosity at 100 degrees Celsius but 5w30 grade oil will thicken less than 10w30 grade oil in cold climate. This means 5w30 grade oil will flow effectively in low temperatures, whereas 10w30 oil will flow effectively in high temperatures because of the smaller temperature window.

What happens if you use 15w40 instead of 5W40?

There is a single benefit to 15w-40 oils though, they will maintain their 40 weight operating viscosity longer than an oil that starts at 5w. This is not rocket science, it takes less friction modifiers to get from 15 to 40 than it does from 5.

Is all 15w40 oil the same?

No. Oils carry a certification and must be selected to meet or exceed the recommendations in your engine manual. Oil standards are normally backwards compatible, but the base oils are different.

What is 15W-40 oil used for?
