All You Need To Know About 1.8t Engine Oils

Everything You Need To Know About 1.8t Engine Oils

Do you own a vehicle with a 1.8t engine? Do you want to know more about 1.8t engines and the oils suitable for them and get familiar with the best 1.8t engine oils? 

You have landed in the right place since I have got you covered with all the necessary information you are looking for!

What Does 1.8t Engine Oil Mean?

In 1.8t, 1.8 stands for the combined volume capacity, while the letter T stands for Turbo. Compared to typical combustion engines, turbo engines use additional compressed air from the turbocharger in the combustion chamber. As a result, they provide better efficiency and power. 

Engine oils with a specific grade and viscosity are meant for specific engines. Similarly, 1.8t engine oils are designed for 1.8L Turbo engines.

Why Do Turbo Engines Need Special Oil?

In turbo engines, the turbocharger pushes extra compressed air, which increases the operating temperatures. The temperature often exceeds 400 Fahrenheit, which is nearly double the optimum working temperature of non-turbo engines. 

Put simply, the engine might seize if you don’t use specialized motor oils. Besides that, there’s a risk of other damages:

  • Decomposition of engine oil
  • Formation of carbon buildups or soot deposits
  • Poor performance
  • Failure of active engine components
  • Decreased engine efficiency

To avoid this, use the special motor oil designed specifically for turbo engines.

Why Synthetic Oils Are a Better Choice for Turbo Engines?

I highly recommend using fully synthetic 1.8t motor oils instead of the conventional ones. The reasons behind the choice of synthetic engine oils over the conventional ones include:

  • They do not often break down or decompose.
  • They offer a better lifespan and go a long way.
  • They do not lose their viscosity quickly.
  • They do not contaminate the engine as much.
  • They offer less wear and tear.

In contrast, conventional oils are much cheaper, but they expose your car to sludge buildup and cause more damage than good in the long run.

Engine Oils Suitable for 1.8t

5w40 engine oil, the most versatile oil, is the best for 1.8t engines. However, you can also use some other engine oils with a viscosity index of 5w30, 0w30, or 0w40 for 1.8t.

I recommend changing the engine oil every 5,000 miles (with proper maintenance and regular car services) for better engine performance.
