Is it OK to mix semi and fully 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.

Fully synthetic oil. Semi and fully synthetic oil. Mineral oil.

Is semi-synthetic oil better than mineral oil?
Semi-synthetics are more stable than mineral oils but less so than synthetics, but they are available and generally perform the functions entrusted to them very well. Which is better? This question is tricky and can’t have a simple answer. Of course, pure synthetic oil is better in terms of technical characteristics.
What is the difference between synthetic blends and semi-synthetic?
Generally speaking, synthetic blends and semi-synthetic refer to the same thing: an oil that uses a combination of conventional and synthetic base oils in its formulation. It’s important to note that, while base oils are a fundamental element of a motor oil’s formulation, they’re only part of the picture.
Can you mix synthetic oil with synthetic oil?
However, the mixed oil won’t harm your engine; rather, the additives in the oils may not be compatible, so it won’t deliver all the benefits of a full synthetic oil. As long as you don’t mix synthetic oils with semi-synthetic oils or synthetic oils with mineral oil, you’ll be OK.
Is it safe to mix engine oil?
Modern engine oils are compatible with each other. They are less likely to harm your engine if mixed together. In the same way, It is also safe to mix full synthetic and synthetic blend oil. However, Mixing synthetic oil with synthetic blend oil can dilute the superior performance of full synthetic oil.

How many km does synthetic oil last?
