Modern cars require many different fluids. Most people are familiar with motor oil. However, many people may not realize that motor oil is coming in different types, classifications and consistencies. In addition to being available in a variety of thicknesses and weights – designed for numerous uses and applications, from engines to complex gear sets – Motor oil is also available in conventional and synthetic varieties. Both types of oils are derived from petroleum and crude oil. However, synthetic oil contains artificial compounds and undergoes various chemical processes to refine it to a greater extent. Synthetic oils contain few impurities and typically provide superior lubrication and heat dissipation than conventional oils.

Today, many car manufacturers recommend that owners fill their car engines with synthetic oil instead of conventional oil. Using synthetic motor oil may allow you to go longer between oil changes, and over time it can provide better protection for your engine’s internal components. However, if your car’s manufacturer recommends the use of synthetic oil and you only have access to a conventional version, you may be wondering if it’s safe to switch between the two. As a former professional mechanic and lifelong car nerd, I am ready to help you.
Yes, you can mix conventional and synthetic oil; This will not harm your engine, but it may eliminate or reduce some of the benefits that come with using pure synthetic oil. The most important thing is that you use an oil of the correct viscosity or thickness as recommended by your car manufacturer. If you don’t know what the right type of oil is for your car, don’t worry; I will discuss that too.

How to choose the right oil for your engine
As mentioned, there are different types of motor oil and brands of motor oil. If you plan to change your oil at home or bring your own oil for a professional oil change service, you may feel overwhelmed by the variety of options. Don’t worry: it’s quite easy to figure out what type of oil your car needs. The best way to do this is by consult your owner’s manual. Depending on your car, you can usually find the owner’s manual in the glove compartment on the passenger side. It will contain a list of maintenance tasks you need to perform regularly to keep your car healthy. In the oil section, the manual gives you some recommended options.

However, if you don’t have the owner’s manual, you can always pop the hood and check the oil filler cap. An oil type, such as 5W-30, should be embossed on the surface of the cap. If none of these options work for you, don’t despair: you can still learn your engine oil type with relative ease. One option is to call your local dealer and ask. Another simple and convenient method is to visit an auto parts store. There you can ask an employee to look up your vehicle in his computer system. The database will give you the type of oil and filter you need to complete your own oil change, and the store will most likely offer you a few suitable options at different price points. If none of these methods work, you’re probably better off visiting a professional shop for your oil change service. The trained technicians know which oil to use when topping up your engine, and the garage may even guarantee their work.
