Can you mix different weights of synthetic oil?

The good news is that mixing different types of oil it will not harm your engine in any way in the short run. Most synthetic and semi-synthetic engine oils are based on regular oil and are compatible.

Can you mix synthetic oils of same weight?

Viscosity is formulated into the synthetic, but there's no problem mixing. You can mix Synthetic and Mineral oils too, if you want.

Can you mix different grades of synthetic oil?

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.

Is it OK to mix motor oil weights?

Given that standards are in place, does that mean you can mix and match oil weights? The truth is simple: don't mix two different oils that have different weights (viscosities). Viscosity Grades might sound pretty scientific, but the simple fact is that this is what keeps your engine running smoothly.

Can you mix synthetic oil viscosities?

Yes. It won't harm your engine to mix, for example, Quaker State^® motor oil with Pennzoil, as long as the oil you use is the weight (or viscosity) recommended in your vehicle owner's manual.

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

Can I mix 2 different viscosity oils?

THE ANSWER IS NO! Even if two different brands of oil have the same viscosity, you still should not be mixing them together. (Why anyone would even consider doing this in the first place is something we cannot comprehend.

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.

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 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.

Can you mix synthetic oil with synthetic blend?

In the end, conventional and synthetic oils are completely compatible. However while you can safely mix synthetic and conventional oils, you're diluting the performance of the synthetic oil. In fact many companies premix them, calling them synthetic blends, and sell them as a mid-grade performance product.

Can you mix full synthetic with semi-synthetic oil?

However, nothing detrimental will occur if you mix synthetic oil with either semi-synthetic or mineral oil. If this was your only option, mixing oils would be better than running out of oil and potentially causing damage to your engine.

Can you go back to regular oil after synthetic?

Myth: Once you switch to synthetic oil, you can never switch back. This is one of the most persistent myths about synthetic oil—and completely untrue. You can switch back and forth at any time. In fact, synthetic blends are simply a mixture of synthetic and conventional oils.

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 two synthetic oils?

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's the difference between 5w30 and 5w20?

5w20 is an engine oil type characterized by its winter rating of 5 and an oil weight of 20 in warmer conditions. It is less viscous compared to 5w30. 5w30 has the same viscosity rating of 5 during winter but an oil weight of 30 during hotter conditions hence it is thicker.

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.

What happens if I 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.

Is 10W40 fully synthetic?

Semi-synthetic oils such as 10W40 have long been the standard. Their base is refined crude oil, which is then blended with additives.

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.

Is it OK to use 0W-40 instead of 5w40?

Substituting engine oils is an issue many people have a concern about, considering that some industry pundits advise against it. In the case of 5w40 and 0w40, you can use them interchangeably as they have almost similar characteristics.

What cars use 0W-40?

0W-40 motor oil. 0W-40 oils are recommended by automakers for many types of European vehicles, including Mercedes-Benz, Porsche and Volkswagen. The viscosity is gaining popularity with American automakers for high performance engines in both cars and pickup trucks.

Is 5w30 thicker than 0W-40?

Now let's compare them when cold. As you can see above, 0W40 at 79.9 cSt when cold, is definitely thicker than 5W30 at 62.4 cSt when cold. In fact, 0W40 is a substantial 28% thicker when cold, even though it is rated as a “0”wt when cold, which most people would expect to be thinner than a cold rated 5W.

What happens if I put 5W20 instead of 0W20?

0W20 vs 5W20 Fuel Economy

Both 0W20 and 5W20 are low viscosity and high-quality synthetic grades that can massively optimize fuel economy. Their properties are the same when used in fair-weather temperatures. Likewise, there is little to no difference between the two versions when used in cold conditions.

Which oil is thicker 0W20 or 5W30?

The 0W20 is thicker than the 5W30 oil when the ambient temperature is cold and hot, and also when the engine reaches its optimal running temperature. The oW20, 5w30, and any other combination of numbers represent oil's viscosity grades.

What happens when you mix oils in a car?

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.
