Oil Buying Guide For 3.6 Pentastar 

The Viscosity

The viscosity is perhaps the single most important detail a vehicle owner has to understand. It decides how your vehicle will perform.

A thicker oil type will be more suitable for vehicles that undergo extreme conditions and rough terrains as it usually takes a heavy toll on the engine.

The thicker motor oils protect the engine by lubricating the engine parts better and creating an oil film layer to prevent any damage.

Thinner oils on the other hand are more suitable for vehicles that are operated under cold temperatures as they are freer flowing and lead to a better ignition. This helps in eliminating the problem of LSPI which is quite common in modern day engines.

The thinner oils however are unable to provide the level of protection that the thicker oils provide to the engine.

The 3.6 Pentastar recommends using either the 5W-20 or the 5W-30 viscosity motor oils which improve the performance of the vehicle by providing a comfortable layer of protection along with a free-flowing oil.

Using any other product in the engine may lead to poorer performances or in some cases may even damage the engine.

The Oil Type

The oil type is the next detail you have to pay attention to. There are 3 major types of motor oils available in the market namely: conventional, synthetic blend and full synthetic motor oils.

First, let us understand the conventional motor oils. As the name states, the conventional motor oil is primitive in nature and has not been treated with base stocks. This may sound nice to a user however this means that they fail to provide enhanced vehicle performance. They are easily outperformed by the synthetic blend and the full synthetic motor oils.

The next motor oil is the synthetic blend type. Just like the name suggests, they have been treated with base stocks to provide your vehicle with a slightly improved performance and may provide some features like corrosion protection or cleaner engine.

However, the full synthetic motor oils easily outmatch the two. They have been chemically treated to help your engine in maximizing its performance. The full synthetic motor oils provide benefits like corrosion protection, cleaner engines, superior wear protection, reduction in engine noise and even provide longer drain intervals and an improved overall performance. 

Naturally, the full synthetic motor oil is the costliest out of the lot. The 3.6 Pentastar recommends using the Full Synthetic motor oils to help achieve best performance and using other products may lead to deteriorated output and can permanently damage the vehicle and shorten its lifespan.

Engine Performance

The engine performance is also relevant to which product you choose next. One should pay close attention to the details of an oil as choosing the wrong one can have catastrophic results. It is ideally recommended to refer to the manufacturer’s guide to find the best motor oil. 

Additional Features

If you still are in two minds about which product would suit your vehicle best, then you should perhaps look for the additional features mentioned on a product.

For instance, if your vehicle has developed a problem of excessive engine noise, then perhaps choosing a product that would combat the problem would be the perfect product for you.

Frequently Asked Questions:

It is recommended to use a full synthetic motor oil in the engine to attain the best results.

It is recommended to use either Pennzoil or Castrol products in a 3.6 Pentastar.

The Pentastar recommends using a motor oil with a viscosity of either 5W-30 or 5W-20.

It holds about 6 quarts of oil.

If you are using the full synthetic motor oil, it is recommended to change oils every 10,000 miles or 16,000 kilometers for ideal performance.

Our Verdict

The 3.6 Pentastar is a high-quality engine that recommends using a full synthetic motor oil with a viscosity of either 5W-20 or 5W-30. The best product for the same would be the Pennzoil Ultra Platinum Full Synthetic 5W-20 Motor Oil. If, you are looking for an economical product, the Castrol Edge Extended Performance 5W-20 Advanced Full Synthetic Motor Oil would also work well. However, the final decision depends upon the user and under what circumstances they operate the vehicle.
