Arriving in the first place is a product on completely another side of the oil spectrum.

This Synthetic Oil by Pennzoil has been developed using natural gas and not crude oil, unlike all other manufacturers on the face of the earth.

Being a new type of oil and so much successful means having some pretty good offerings.

This natural gas-based oil has been designed using the brand’s very own gas-to-liquid PurePlus patented technology.

Using this technology, the brand brings some pretty big claims for all compatible vehicles. One of the major ones is saving around 550 miles of fuel every year if you use this product.

But, of course, this is when compared to a dirty engine. And all products in front of this one are considered dirty.

Not being a crude oil-based product has its advantages. One of the biggest ones is the wear protection provided by this oil.

This is not a claim but has been proven by the 5W-30 wear test that this Pennzoil oil is the excellent out of all other products in the same category.

There is always bound to be one, and in this case, Pennzoil took the lead.

What this means in real life is that you are looking at better engine protection than ever before, which cannot be matched with any other product on the market.

Deposits are something that disrupts the flow of oil. This, in turn, reduces the engine’s ability to perform efficiently. You may notice that by loss of horsepower in your vehicle.

Well, this one prevents that too. So, you won’t ever have to worry about the engine throttling due to deposit formation.

Some buyers received products that had been on the shelf for quite some time. Some were so old that there was silt collected at the bottom.

The brand needs to look into this because old products have less effectiveness than fresh ones.

  • Gas-to-liquid PurePlus technology
  • Best in class wear protection
  • 550 miles per annum fuel saving
  • Reduced chance of deposit formation
  • Can work in extreme temperatures
  • Old bottles being shipped

Pennzoil should not ship bottles that are more than a year old, maximum. This is because those oils have poor performance.

However, the product itself is excellent, and you can’t get anything better than that.

Taking the second spot with around 13500 ratings is the 1598EF Synthetic Oil by Castrol.

Castrol has almost always taken the first spot on my list, but the second isn’t bad either. After all, all of these products were chosen out of hundreds of different options.

This extended performance motor oil has been designed for people looking to get the most out of one oil change.

Not 5000 or 10000, this product has been designed to run for 20000 miles in one go. This is truly incredible and almost too good to be true.

But when you see the brand name, then it makes sense. One might think that the brand has pulled all the stops to make this one achieve this mileage.

But it still provides excellent performance. This is possible thanks to their very own Fluid Titanium Technology, which is perfect for vehicles used extensively.

The wear protection of this oil is six times better than the industry standard. The company has gone out of its way to make sure buyers get the maximum engine life possible.

Moreover, the oil also has ten times more resistance to high temperatures than the industry requirements.

What this means is that you won’t have to worry about the oil thickening at high temperatures.

In layman’s terms, the viscosity of this one will remain consistent no matter the temperature.

The oil also helps in reducing fuel consumption. The saving in fuel is equal to the required amount for 0W grade oil. That is great!

Buyers complained that this product causes performance issues for their vehicles.

They mentioned reduced performance and sometimes knocking issues as well. This means that some oil batches must be defective.

  • 20000-mile drain interval
  • Fluid Titanium Technology
  • Ten times more temperature resistant
  • Six times better wear protection
  • Performance issues

On the probable occasion that you receive a product that is not defective, you will have an excellent experience with this one.

Castrol has proved to be one of the best brands to satisfy users’ needs and demands.

3. Shell Rotella Gas Truck Full Synthetic Motor Oil

Shell is another highly popular brand. Their products are renowned throughout the world. Shell is regarded worldwide due to its high-quality oil products.

This Shell Rotella Synthetic Motor Oil is no exception. With close to 1500 five-star ratings, this product is famous among users.

Let’s see what makes it good!

This oil has been designed to work with all sorts of supported vehicles, no matter the wear level.

It can work in extreme conditions. Whether the temperature gets hot or cold, this one will not fail on you. That’s a guarantee.

Whether you use your vehicle for towing or long driving, the oil having a breakdown should be the least of your concern.

The brand assures buyers that this product is miles better than all other conventional alternatives out there.

Being synthetic oil already makes it superior, so there is no doubt that it will be better. The wear protection of this product was tested against the industry standard.

And guess what, it easily surpassed those requirements. The test used is the Sequence IVA test. And, of course, this one provides you with excellent sludge and deposit protection.

Sludge can harden over time and transform into deposits. These deposits are present in the pipeline, and they restrict the flow of oil.

So you won’t have to worry about restricted horsepower anymore. Being synthetic oil, it already has some features that come by default.

For example, the base oils allow for better rust protection. You are also getting a product that is not that volatile.

Volatile oils have a short drain interval. This is not the case with the Shell Rotella.

Shell promises a rebate of $10, which they do not fulfill. This is a very poor service which should be corrected as soon as possible.
  • Can work in extreme temperatures
  • Low volatility
  • Excellent sludge and deposit protection
  • Protection from rust
  • Rebate issues

Being a conglomerate in the world of oils, Shell should not do things like rejecting qualifying rebates. If you don’t care about that, then you will be content with the oil’s performance.

4. Valvoline Daily Protection 5W-30 Synthetic Blend Motor Oil

So, you cannot overwork your vehicle but still want a product that provides you with decent protection from everyday engine issues.

This Valvoline 5W-30 Synthetic Blend Motor Oil is best suited for you. Although synthetic oil is superior to blended oil, in this case, a blend will be more than suitable for your needs.

Plus, when you see Valvoline’s name with a product, you are bound to be impressed by it.

The brand has used its high-quality in-house additives, which have been designed to reduce sludge and deposit formation in the engine.

This makes sure that the engine does not get overworked and works with full efficiency.

Combining the same additives with premium base oils, you are getting excellent wear protection.

Worn-out engines not only burn oil quickly but also have a shorter lifespan. This oil solves that issue. It is also capable of working at high temperatures without having a breakdown.

This is a feature not present in most oils, which causes issues for vehicles. The oil also provides you with better fuel efficiency.

Now, it is rare to see something like this just by performing an oil change.

Let me clarify!

This one significantly reduces friction between the engine parts. Friction makes the engine work harder than it is supposed to, which also increases fuel consumption.

Reducing that directly ensures better fuel economy and stable performance. Overall, this product has been designed for people who use their vehicles in normal scenarios.

However, if you don’t, it is recommended to check out some of the other options. The description of the product does not match what is being advertised.

For example, the pictures state that this is a conventional one while the description does not. This confuses buyers.

Some also stated that they received the conventional variant, making this one falsely advertised.
  • Controls sludge and deposit formation
  • It can easily work at high temperatures
  • Better fuel efficiency
  • Reduced friction
  • Wrong product description

Valvoline needs to step up its game and provide the correct descriptions for its products. This breaks the buyer’s trust as they receive a product they did not order.

Regardless, the oil is excellent and is a high-performing one.

Finally, taking the fifth spot on this article is this Synthetic Motor Oil by Mobil 1.

This brand is yet another one that is regarded worldwide for its high-quality products. This one proves that. It is available in five different options.

You can choose from extended performance, extended performance high mileage, full synthetic and high mileage options.

We will be focusing on the full synthetic one. This product has been designed to work for a long interval. It can work for around 10000 miles between oil changes.

It will be able to work at all temperatures and will not break down at extreme ones. If you can overwork your vehicle, this Mobil 1 oil should be on your consideration list.

To clarify, this one can work in temperatures as high as 500-degrees Fahrenheit and can work in cold temperatures, which are as cold as -30-degrees.

Thanks to the low viscosity of the oil, the cold limit is possible, which makes it easier to flow.

This oil also meets the ILSAC-GF6 requirements, which ensure that it will reduce oil burning at LSPI. For those who don’t know, LSPI means low-speed pre-ignition.

Oil is burnt a lot at that stage. Controlling that automatically means extended drain intervals.

And, as expected with high-end oil, this one protects your engine from deposits and sludge build-up.

You can rest assured that you won’t ever have to face the issue of the engine throttling just because of reduced oil pressure.

All of this ensures that your engine will have a better and healthy life with improved performance.

Finally, Mobil 1 has made a product that will satisfy buyers. Buyers had three major issues with the oil.

They either received bottles that were leaking, wrong orders and sometimes complained that the product was overpriced.

The brand was reported with a problem of leaking bottles and some people reported that wrong products were delivered to them upon ordering.
  • 10,000-mile drain interval
  • Meets ILSAC-GF6 requirements
  • Reduced burning at LSPI
  • Protects from deposit build-up
  • Leaking bottles
  • Wrong product delivered

With over 6000 people satisfied with their purchase, some were not. Therefore, the seller should look into these issues and resolved them.

Frequently Asked Questions

Q1. What Oil Does A 3.6 Pentastar Take?

The 3.6 Pentastar needs a 5W-20 oil for proper functioning. The quantity must be six quarts so the engine can work efficiently.

What will happen if I pour a 5W-30 oil in a 5W-20 engine?

It certainly won’t seize your engine, for sure. But you can expect worse performance as you did not go for the recommended specs.

The Valvoline oil on this article is a 5W-30 oil. Although it is not the recommended oil for your vehicle, it still performs outstandingly.

So for the 3.6 Pentastar, it is recommended to go for the 5W-30 only if you buy from Valvoline.

Q2. Is Synthetic Oil Better Than Conventional Oil?

There is no comparison between the two. Base oils used in synthetic oils are of significantly higher quality. They’re also a lot cleaner and last a lot longer.

In addition, synthetic oils are more stable, emit less harmful gases, and protect the engine from rust and corrosion.

All of this contributes to the vehicle’s health. Although it is more expensive than other options, it is worth it.

It is even far superior to blend oils which are a mixture of conventional and synthetic oils. Check out the next question as to why mixing is not preferred.

Q3. Can I Mix Synthetic And Conventional Oil?

This is a question that is frequently asked in forums online. Normally, something like this should be avoided because the chances are that the mixture will cause issues.

However, when you look on the technical side, the base oils are nearly identical, implying that they can be blended.

Therefore, only use this option as a last resort when you are in between an oil change and don’t have the required quantity.

Q4. How Often Is It Recommended To Change The Oil On The Pentastar?

The rule of thumb is that oil needs to be changed every 5000 miles. But that is a thing of the past. Oils produced nowadays go through high-quality refinement processes like never before.

They are cleaner, use higher quality base oils, and with most of them being synthetic, you are getting superior performance gains over conventional oils.

But there is always a limit to when oils need to be changed. Synthetics can work for around 10000 miles, but the recommended interval for change is 7500 miles.

For blend oils, you need to change the oil every 5000 miles. In the case of oils like the Castrol one, you can go up to 15000 miles.

The reason for the real-life intervals being short of the brand’s claims is that the oil starts to lose its effectiveness after some time.

You don’t want to be driving around with oils that are not effective. But, of course, then you might be looking at expensive repairs.
