Can You Mix Full Synthetic Oil With Synthetic Blend?

Proper engine lubrication requires the selection of the correct engine oil. Three types of engine oil are available: fully synthetic oil, synthetic blend oil, or conventional oil. A synthetic blend is a mixture between fully synthetic oil and conventional oil.

It is possible to mix synthetic oil and blended oil. The short answer is yes. There are a few things you need to remember when combining the oils. This is how it works.

What happens when you mix synthetic oil and synthetic blend oil?

Synthetic oil is a mixture of synthetic and conventional oil. Different types of lubricants share the same base so they can blend well without any adverse effects. Synthetic blends typically contain 70% conventional oil and 30% fully synthetic oil. 

As you add more synthetic oil to the blend, your synthetic oil concentration will rise. This will result in better lubrication because synthetic oil has a higher quality. However, fully synthetic oil has less benefits than conventional oil because it contains conventional oil.

Can you mix full synthetic oil with blended oil?

You can mix synthetic oil and a synthetic mixture. This will not affect engine oil lubrication. Because synthetic blend oil is cheaper than synthetic oil, but retains almost the same quality and add-ons, synthetic oil is on the rise.

Combining synthetic oil and synthetic blend oil is a normal practice that will not impact lubrication. It can increase engine oil’s life and performance at high temperatures.

Consider these factors when adding synthetic oil to a synthesized blend:

1) Viscosity: Make sure to check the viscosity level of any synthetic oil that you use. Engine lubrication may be affected if the viscosity level of the synthetic oil you use is different. A synthetic blend oil that contains a 5W-30 and a 10W-40 synthetic oil can reduce its viscosity.

This will result in a combination that is thicker than 5W-30 and thinner than 10W-40. This will not have any significant impact on your driving experience, but it can cause problems when you drive at extreme temperatures.

If there is no emergency, or the oil is very low, it is best to top-up the oil with oil of the same viscosity. The recommended viscosity to use for your engine is listed in the owner’s guide.

2) Brand: It is recommended to use the same oil brand when topping up. Because each manufacturer uses different methods for adding additives, it is important to use the same brand of oil when topping up. 

Some old oil can remain in the pan after the oil has been changed and will mix with the new oil. If the old oil is between 15-20% and 20%, it will not be a problem to add oil from another brand.

It can be quite alarming to find that the concentrations of lubricants in different brands are split 50-50. Additives react when two brands of engine oil mix. reduce the age of the engine oil. It is always a good idea to use synthetic oil from the same manufacturer to your synthetic oil blend.

Which oil is better: Full Synthetic or Synthetic Blend?

Prices

The price of synthetic blend is much lower than that of synthetic oil. It is mostly blended with conventional oil which is cheaper than full synthetic oil. Different brands use different proportions of synthetic oil. A synthetic blend is more expensive if it contains more synthetic oil.

Qualitative

Full synthetic oil is the clear winner in terms of performance and quality. They can withstand extreme temperatures better than synthetic blends and provide the best lubrication. While synthetic blends can only go 5,000–7,500 miles, fully synthetic oil can last for about 10,000–15,000 miles.

Conclusion

It is possible to mix synthetic oils with fully synthetic oils. It is easy to mix oil and it won’t affect engine lubrication. Full synthetic oil has some drawbacks. However, synthetic oil is more beneficial than conventional oil. However, engine oils will perform better if the synthetic oil content is higher. 

You should ensure that the oil you use is the same brand and viscosity. Overuse of synthetic oil can damage gaskets or seals in older cars. Make sure you add synthetic oil according to your requirements.
