We’re going to give it to you straight: Yes, you can safely switch to synthetic oil. But it would probably help to know the details about what we’re talking about — precisely why this question would even come up in the first place. And it does — a lot.

First off, let’s talk about what synthetic oil is. First, there’s a base oil that does most of the work of lubricating engine parts. It’s lab-created, as opposed to being a product of the refining process of mineral oils pumped out of the ground. There are also performance additives (in powder form) in many synthetic oils and a carrier oil to suspend these additives in the mix.

The most often cited myth concerning synthetic oil is that it will wear down the seals in your engine and cause leaks. That isn’t true. Well, for the most part, anyway.

Like many myths, this one is based on fact. Early synthetics were made of esters, which were harder on seals, especially those made of neoprene. However, synthetic oils have come a long way since the early 1970s, and they’re much more superior to delicate seals. But while synthetic oil won’t create a leak, it will find one. Its streamlined molecular structure has no mercy for cracked or otherwise marginal seals. The oil and its additives may even clean deposits from the engine, which is good unless those deposits act like spackles on questionable seals.

Now, let’s talk about the weight of the oil.

One way to protect your engine from damage is by using the right type of engine oil. Choosing the wrong kind of motor oil can affect the performance of your car engine. There are different types of motor oils in the market, and they differ in thickness, viscosity, and ability to withstand high temperatures. Most vehicles have a specific type of oil recommended for them. However, what harm would it cause the use of motor oil in your car?

Can I use 10w30 instead of 5w30? If that question has ever run through your mind, then you are on the right platform to get answers. The first number, 5 or 10, is the measurement of how easily the oil will pour under low temperatures. The second number, which is 30, indicates the oil thickness under high/operating temperatures.

So, for the easy answer – no, you won’t ruin your engine by putting synthetic or a 10w30 when your car says that you should put 5w30 weight in your engine. But if you have any follow-up questions – please give us a call at The German Auto Doctor.
