The difference between synthetic and mineral oil is greater than you might think. Both types have a different origin, composition and operation. Choosing the right type of oil depends on your car, its use and maintenance schedule. In this blog, you'll discover exactly what they are, and when it's best to use which one.
Mineral oil is refined directly from petroleum and is relatively easily produced. It contains impurities that, while largely removed, still cause less stable performance at high or low temperatures. This oil is mainly used in older cars or engines with simple technology.
Synthetic oil is chemically processed to create a pure, stable structure. As a result, it is more resistant to temperature changes, ages less quickly and offers much better protection against wear and tear. Modern engines almost always require fully synthetic oil.
Synthetic oil offers better cold-start, better oxidation resistance, less sludge formation and longer drain intervals. Combined with the right additives, this ensures maximum engine protection. Our Premium Performance 5W30 is an excellent example of a high-quality synthetic oil.
The price is often a bit higher than mineral oil. But this investment pays off in less wear, better performance and longer life of your engine. For older engines, synthetic is sometimes too thin - in which case mineral oil remains an appropriate choice.
Semi-synthetic oil is a blend of mineral and synthetic base oil. It offers better performance than pure mineral, at a lower price than full synthetic. It is an intermediate solution for those who want more protection but do not have the highest budget.
If you switch from mineral to synthetic oil, preferably do so with a complete oil change including a new filter. That way you avoid mixing different compositions. In doubt about your engine? Use our online oil consultant or view the information page.
The right oil depends on engine type, year of manufacture and manufacturer's requirements. For modern vehicles, fully synthetic oil is almost always the right choice. For old engines or vintage cars, mineral oil may still be appropriate. Always be guided by specifications as well as common sense. Our location in Weert helps you get started with targeted advice.
1. What is the main difference between synthetic and mineral oil?
Synthetic oil is chemically processed and more stable, while mineral oil comes directly from petroleum and is less pure.
2. Is synthetic oil always better?
For modern engines it does. It protects better, lasts longer and remains more stable at high and low temperatures.
3. When do you still use mineral oil?
In older engines that are not suitable for thin synthetic oil or where manufacturers recommend it.
4. Can I switch from mineral to synthetic?
Yes, but do this at a full oil change with new filter to avoid mixing.
5. Is synthetic oil more expensive?
Yes, but your engine stays cleaner, lasts longer and you don't have to change it as often.
6. What is semi-synthetic oil?
A blend of mineral and synthetic oil, as an intermediate solution in price and performance.
7. How do I recognize good synthetic oil?
Look for specifications such as ACEA C3 or API SN, and choose oil from a reliable supplier such as Solution Oil.
8. Can synthetic oil cause damage in old engines?
Only if the engine is not built for it. When in doubt: consult the manufacturer or choose semi-synthetic.
