If you’re in a hurry and still want to grab the best GDI engine oil, go for the Castrol Edge 5W-30, confidently.

Before heading down to the best products, let’s discuss a little about what a GDI Engine is.

What is Gasoline Direct Injection (GDI) Engine? Gasoline Direct Injection (GDI) engine is a combination system for internal combustion engines that transfer petrol/gasoline directly into the main chambers/manifold to operate.

As compared to your average engine, the GDI engines are known to be more powerful and efficient in performance

Although this type of engine reduces engine emissions while improving the car’s performance, there are certain disadvantages associated with it too.

Best Oil for GDI Engine

Unlike a normal car engine, the GDI engine does not have an internal valve cleaning system which means the more petrol it burns, the more residue will be built and hence, clogging the engine after a while.

This is why, it is important to feed it with the top-rated GDI engine oil that’ll decrease the formation of the residue, promising high performance every time!

GDI Engine Oil Buyer’s Guide:

GDI engines are sensitive yet extremely powerful, thus to ensure their performance isn’t compromised, you need to use a special formula to keep them healthy.

Feeding a GDI engine with average oil can decrease its life and performance; hence, it is crucial to choose the best synthetic oil for it. But of course, for someone with the least knowledge, the decision of which one is the top-notch quality synthetic motor oil can be a hard one!

Let us tell, we’ve put in a lot of time and effort to curate this article that’ll help people in finding the best fit for their car’s engine. Thus, the following are the factors that determine the quality of motor oil, helping you decide whether it is fit for your vehicle or not:

Synthetic or Mineral Motor Oil

synthetic gdi engine oil

For years we’ve been using mineral oil for our cars, and yes, you’d say you never have faced a problem. Although, mineral motor oil is less costly than a synthetic one, but may cause trouble for your engine!

Unlike synthetic oil that is extracted from natural resources, non-synthetic oil is taken from crude oil, which is usually very dense in viscosity.

Moreover, the average motor oil tends to clog the pistons due to the deposition of residue after a few kilometers, and hence, you need to get it changed regularly to ensure the engine’s performance is uncompromised.

But does the GDI engine need synthetic oil? Since we’ve shifted to synthetic engine oil, we’ve seen a visible change in the performance of our car.

We’ve gotten rid of the knocking which was caused by clogged pipes and the engine now runs much smoother.

Synthetic oil as compared to the average crude-oil-based Mobil reduces oxidation which in turn helps keep the engine clean, healthy, and strong. Moreover, it will protect your GDI oil from sludge, corrosion, and wear.


Viscosity refers to the Mobil’s capacity to withstand extreme temperature. The number on the left refers to the low viscosity and the lower the number is, the more efficient the oil will be during lower temperature conditions.

If you look at the right side of the range, it refers to the oil’s capacity to work under higher temperatures. Remember, during extreme temperature rise, the temperature of the engine can go up to 400 degrees Celsius which can affect its performance.

Thus, the thicker the viscosity of a synthetic GDI engine oil, the better it is for your engine!

API, SAE, and ACEA Standards

If you ever had a chance to look at the bottle/containers of synthetic motor oils, you’ll see a mix of numbers and alphabets on them. What are these?

These refer to the standards set by law that help define the quality of a Mobil. Also, these indicate whether the oil is fit for petrol engines or diesel cars.

Likewise, the standards also give you an insight into the oil’s tendency to reduce oxidation and fight wear, sludge, and corrosion.

If you’re for motor oil that’ll protect your engine and prolong its life, make sure the product you choose to abide by the quality rules/standards.


Most car owners know how expensive motor oil is and if you’re planning to switch to the synthetic one, let us be clear, it is even more expensive! But of course, when it comes to the performance of your car, one never wants to compromise on things like these.

Yes, the synthetic engine is very expensive but this does not mean you cannot find many more affordable options that offer the same quality. It is better to do your research, but a glance at the prices and set your budget likewise.

Reduces Oxidation

Are you listening to that noise? Seems like the engine is knocking! Or are you having a tough time starting a cold engine quickly in the morning? We’ve faced similar problems and we are sure, you have to at some point in time.

But why does the engine make knocking sounds? This is because of the clogged pipes and pistons as a result of oxidation.

Oxidation is a process where the engine oil breaks down into different components where the best ones power the engine while the residue deposits inside the pistons when it gets no place to escape.

Good, synthetic motor oil reduces the process of oxidation, hence decreasing the deposition of residue and saving the pistons from clogging, and letting you enjoy a smooth drive every time!

Some Additional Information Right Here

Since we’ve presented you with a long list of GDI engine oils that we find probably the best, choosing amongst these can be confusing for many.

Hence, this is why we thought of shooting a quick comparison your way between the two most popular Mobil brands: Pennzoil Platinum and Castrol edge titanium.

So guys, put on your seat belts because the call to choose the best is surely going to be a tough when.

Pennzoil Platinum vs. Castrol Edge Titanium Engine Oil

Pennzoil vs Castrol Engine Oil

In terms of prolonging your engine’s life, which one is better if you, we’d say both!

Both Pennzoil platinum and Castrol edge titanium engine oil consist of titanium technology that works hard to reduce oxidation which keeps the engine protected against sludge, corrosion, and wear.

Moreover, both the motor oils are fully synthetic, attained from natural resources that decrease the deposition of residue, save crucial engine parts from harmful emissions, and keep the engine clean from clogging.

Also, these are great at managing the engine’s performance at an extreme temperature which is why your GDI engine stays happy and healthy when other engines are unable to perform well.

Nonetheless, if you’re looking for premium quality synthetic oil that is ideal for your GDI engine, both Pennzoil and Castrol’s motor oil are a brilliant choice.

Although, these two are pretty much similar in formulation and act, the only difference that we observed is that as compared to the latter, Pennzoil’s Mobil is 40% more efficient at keeping the engines cleaner and improving the engine’s performance.

While Pennzoil may take a point here, the Castrol motor oil isn’t far behind either. Castrol’s edge titanium motor oil too keeps the engine clean but not to the extent that Pennzoil’s oil does.

Moreover, this one is suitable for oil engines only yet promises to increase the efficiency of your car’s engine, especially on a cold day.

Furthermore, Pennzoil platinum is a little cheaper than Castrol motor oil, thus with barely any difference in the results, which one you choose is completely your own decision to make!

The Best NOACK Oil & Test Values

Do you know what NOACK oil is or what the volatility test is for? We bet you don’t!

The NOACK volatility test was designed to determine how much weight lubricants like engine oil lose during the process of vaporization.

The oil is vaporized at high temperatures, and the more the motor oil vaporizes, the thicker and denser it becomes.

Thus, what does the value indicate? The thicker and denser the motor oil is, the more damage it will cause to your car’s engine. It is likely to clog the pistons and pipe, decrease the efficiency of the engine and lead to heavy damage.

Conventional mineral oil is formulated from impure substances and hence quickly responds to volatilization.

The oil vaporizes at high temperature, leaving behind dense impurities which can clearly be seen deposition on the inside of the engine and suffocating the passage.

On the other hand, synthetic motor oil is extracted from natural resources with the presence of very few impurities which is why; it is more resistant to the process of volatilization.

Thus, when you wish to choose the best Mobil for your GDI engine, make sure you opt for synthetic engine oils, which although are expensive but promise to prolong the life and improve the performance of your engine.
