Should I Use a Full Synthetic-Blend?

Absolutely you can, in fact if you want to save a bit of money you can go with using a blend that mixes both types. The best oil brands to date are known to have a variety of different mixtures (not just full synthetic).

Typically you’ll find something like this with Castrol, Rotella, Valvoline, and many others where they reduce the price and as a result… reduce the engine life protection. 

However, this is completely fine on cars, trucks, and SUV’s which aren’t necessarily high performance. Whether you’re talking about diesel or petrol, this fact still applies.

What are the benefits of Synthetic Oil?

If the motor oil is so vital to your vehicle, how come no one ever talked about it in length? Well, probably because there’s a preconditioned thinking that all men know everything about car without asking or reading about it. After all, cars are manly thing, right?

Unfortunately, this attitude can leave you in the dark when it comes to knowing synthetic motor oils. There are various brands that offer quality but only a few will get deeper into the topic and explain why do you need full-synthetic . Here you will read a couple of reasons why bother with synthetic motor oils.

#1 Keep The Heart Running for MUCH Longer

Synthetic motor oil is not the only choice you can use for your car but it’s by far the best way to go. Since it’s purified, refined, and distilled, it offers more benefits than conventional motor oil. The engine needs a lubricant to keep it clean and running, so both oils will do good.

However, a synthetic motor oil offers another feature which conventional blends do not. Because of its chemical benefits, a synthetic motor oil will rarely turn into sludge, like a conventional oil does over time. The engine will keep its performance and efficiency at optimal levels when using only full-synthetic, which means your car will work smoothly and the engine will be clean. 

#2 Excellent Protection in LOW temperatures

When your car stays outside over the night, the oil in the engine settles, so it takes more time to start the car in the morning. This is a normal thing for each vehicle; however, the time that takes the engine to start running in the morning is much shorter for vehicles that use synthetic motor oil. Again, the secret is in the chemical composition of synthetic oils, which come with greater velocity, allowing the engine to start working quickly even at the low temperatures.

Why is this important? Because the engine can get damaged if it’s exposed to low temperature for too long. Thus, by using a synthetic motor oil you will prevent any friction that may occur during cold weather and lower temperatures, and you won’t face any difficulties when igniting the engine in the morning or after a period of not driving the car.

#3 HIGH Protection from Excessive Wear

Besides keeping the engine protected from the outer weather conditions, synthetic motor oil also prevents the inside of the engine to get damaged. All the parts that form the engine are extremely engaged when the vehicle is running, so it’s crucial to lubricate them properly to avoid breakdowns at high speeds or some unusual working conditions. 

If we have in mind how fast each of the parts is moving and multiply it by how many hours per day we’re using our vehicles… Well, you probably get the idea that the engine is under a severe stress. Thus, a proper synthetic oil is crucial to create the barrier between the parts in the engine, so they can work at their best performance for a long period of time.

#4 Works in High Temperatures

Low temperatures are not the only weather related problem that might affect the engine performance. The heat is another thing that you should be aware. While running, the engine gets heated, and most conventional motor oils evaporate due to their lack of resistance to high temperatures. However, synthetic motor oils are designed to resist these temperatures and enable the engine to work correctly despite the heat within the car. The vehicle won’t get easily overheated which means it will last longer and perform better.

#5 Works Extremely Well with Turbocharged & Supercharged Automobiles

Most modern types of cars and trucks have smaller engines (compared to before) to offer better fuel efficiency, so the car manufacturers added a turbocharger that boosts the power and keeps the car at certain speed. 

The issue with this type of engine is that turbocharger can significantly increase the temperature inside the vehicle, which can, again, affect the overall performance of the car. With the right synthetic motor oil – and we’ll talk about different oils in a bit – the turbocharger will be lubricated quickly, enabling the engine to work properly even at peak performance.

Now you know why you need to bother with synthetic motor oils. They play a vital role in the overall performance of your car, so it’s essential to pick the right type to get the MOST out of your vehicle. In the next section, we’ll give you the best of the best motor oils for 2018 with all the pros and cons of using them

Need help changing your motor oil?


Now that we’ve covered all the 7 best synthetic motor oils for 2018, it’s time to recap. Firstly, having a reliable synthetic motor oil is crucial for keeping your engine working properly and last long.

Without a lubricant, the engine gear will slowly start to decompose, leaving the engine unprotected and prone to friction. 

On the other hand, a synthetic motor oil is required to level the temperature inside the engine.Keep in mind that most of the synthetic motor oils that we’ve reviewed in the upper part of the article work fine on every type of vehicle but before you use any of them, make sure you check the compatibility for your type of vehicle. If you’re not using a synthetic oil yet, there’s a good reason why you should consider switching to one. After all, you just want the best for your car, don’t you?
