Royal Purple SAE HPS Full Synthetic Oil – Top High Mileage Synthetic Oil
I will start off with, what in my opinion, It is the super good . It comes recommended by several mechanics, and there is a reason for that too. This very popular HPS Full Synthetic Oil product is better than most other brands of fully synthetic oils and of course, conventional ones as well.
Maximum wear protection
Zinc/Phosphorus Anti-wear additive
Exceptional oxidation stability
The first feature I noticed about this oil is its wide range of available viscosities. You get 5W-30, 5W-20, 10W-30, 10W-40 and finally, 20W-50. This simply means that you will probably be able to use it in most sort of climates, whether they are warm or cold.
Next is the additive blend in this oil. It has Royal Purple’s proprietary Synerlec additive technology. This, along with the zinc/phosphorus anti-wear additive blend, pumps up its effects by a significant degree. The additives included further protect the engine against metal to metal contact, even when it is under stress.
The high film strength acts as a coolant. It reduces the wear and heat of the engine. Not just that, it further extends the life of the engine as well.
The seal between the piston ring and cylinder wall is improved. This is what improves on the horsepower and torque. It helps with the fuel economy as well.
The oxidation stability is better in this as well. This means that this oil will last longer before forming any residues. It improves on the mileage, and it cuts down on emissions as well. The advanced full synthetic oil solvency helps with the deposits. This effectively improves fuel economy and the lifespan of the engine
There is only one noticeable con in my opinion. And that is, price of engine oil is higher than the average stuff. But then, considering that this is pure synthetic oil instead of a blend, it is justified as well.
Better High mileage oil
Better engine life
Better for the environment
Pure top rated Synthetic Oil
Better fuel economy
Not so affordable
I would recommend that you buy this oil when your vehicle is out of manufacturer warranty. I noticed considerably high efficiency overall. It worked on all levels as it claims. The rate is a bit of a let-down. But on my part, I am willing to compromise on it for what this oil offers. It is specially meant for protecting the engine and expanding the life span. Honestly, consistently using this high performance engine oil brand for the last two years, I can vouch for this claim. So if you haven’t tried it out by now, I would suggest that you give it a go.
Mobil 1 Extended – Best Synthetic Oil For Diesel Engines
This comes second on my list. I was originally impressed by their full synthetic oil filter before I decided to give this synthetic oil a try as well. As usual, Mobil engine oil did not disappoint. I would still prefer the Royal Purple over this, but that is not due to any deficiency on the part of the latter. Nevertheless, I will move onto the specifications first.
Full Synthetic Oil Formula
Excellent engine oil lubrication
Good Engine Protection
Longer Engine Life
Firstly, it is pure synthetic oil. That is better than any other varieties out there. It lasts longer and offers better advantages on all levels. This advanced full synthetic Oil formula is especially meant to prolong the life of the oil. It refrains from sludge and deposit buildup.
The rest of it comes with this being pure quality synthetic oil. One of the major criteria of good engine oil is the lubrication it offers. This oil does fulfill that as well. It protects the engine parts against too much wear and tear. And that too under a variety of operating conditions.
Its combination of additives helps to protect the engine. And it serves as a barrier to oil breakdown. This protects the metal parts of the engine.
It provides the basics as well. That includes good oxidation stability. This increases the life of the oil. That means that it takes time to build up any deposits. Or as I mentioned, this formula is exceptional in that area. And it also helps it to function well even in warmer temperatures.
Besides, it serves well in cold climates too. It goes well with engine seals and improves the lifespan of the engine.
The major con I can find about this product is that the additives used are not properly stated. This way, I can’t figure out the exact mechanics of the product. It serves its purpose well. But I can’t be specific about it.
Prolonged oil life
Refrains from deposit formation
Controls oil breakdown
Compatible with engine seals
Good oxidation stability
Works well in low temperatures
Unknown additives used
I won’t say that I do not like this oil because that is not true. It works as well as the Royal Purple oil. However, it does not offer anything extra. And the Royal Purple works in versatile temperatures. That said, you can give this one a try too if you want a change. I do use it on an alternate basis. And the lubrication it offers is smooth as well. That is a good perk of this oil.
Pennzoil, as you know, is one of the most well-known brands when it comes to automotive engine oil. This particular oil is, in my opinion, the best synthetic oil that they have launched ever. It is just the thing I need when I am on a long road trip.
Formulated with PurePlus Technology
Drives extra 550 miles
Better viscosity level
Protects in extreme heat
This PurePlus Technology incorporated in this synthetic oil is what makes it unique from the other two. It helps the liquid maintain a low viscosity, especially at colder climates. This is particularly useful because oil with thick viscosity will demand greater stress from the engine while pumping the oil. This helps reduce the load to a great level. This is achieved by combing the synthetic base oils with high-level additives. Even this base synthetic oil is made by compressing the pure natural gas. This is vastly different from the usual crude oils that are used for base synthetic oil. In fact, it is 99.5% more refined.
And the main part is, along with a comfortable consistency at a colder climate, you get the same at warmer ones as well. This has been proved under oxidation tests using base synthetic oils from other groups.
The engine and the synthetic oil are both protected well at low and even high temperatures. Engine protection is a big issue when it comes to any best synthetic engine oil.
While using it, I did notice that the chance of oil evaporating from heated engine surfaces, especially piston rings, is a lot less as well. This is very useful as the oil is used to its full potential.
However, in spite of these precautions, there have been complaints from a couple of my friends regarding its longevity. So if you are not prepared to take the risk of changing the full synthetic oil a bit more frequently, this is probably not for you.
Consistent viscosity level at colder climates
Base oil is made from natural gas
Less wastage of oil
Oil is better protected in the engine
May not last that long.
Other than the longevity issue, I did not experience any such problems regarding this oil. Nevertheless, this is very good at maintaining the proper viscosity, even at extreme temperatures. Its restrained oxidation helps with hot weather. And the PurePlus technology is good for colder ones. The main part was the absolute lack of crude oils. Even most synthetic oils are chemically treated crude oils. I liked the fact that this product deters entirely from them. So yes, I will suggest that if you live in a hill station, this oil is really good to use. So, you can give it a try.
This oil steals the show when it comes to pure performance. You can even use it with sports and commuter vehicles. In fact, that is what I listed this product for. But you can use it for conventional vehicles as well.
15000 miles performance range
Maintains viscosity under pressure
Titanium FST Feature
Its primary and most significant feature has to be its mileage. 15000 miles is a huge distance. On the longer road trips, it is always tiresome to replace the oil every few miles. With this oil, I do not need to face any such issues.
Apart from that, it is built to handle large amounts of pressure overall. This is useful considering the mileage it is capable of packing. It won’t do to have the engine fail in the middle of it. But this is due to the titanium additives blended into the oil.
Thirdly, we have here the muscle to hold the viscosity stability and that too even under tremendous pressure from the engine. The castrol engine oil won’t thicken due to extreme heat, and this would ensure minimum deposits and sludge.
On the downside, I noticed that this oil is a bit thick in structure. So even though the viscosity remains the same, it creates a similar effect. It doubles the pressure due to this texture, and this can cause a bit of problem. It is not that noticeable. But it is there.
Increases engine life span
Can withstand pressure
Thick oil texture
Oil pressure can increase
I wouldn’t have voluntarily tried this oil out had it not been recommended to me by my mechanic. And I don’t regret it. I took a five-day long road trip, and it served me fabulously. However, as good as it is on mileage and all the factors surrounding it, it does lack a couple of points. I am not too sure about the emission level of this castrol oil. It does boost up the lifespan of the engine as well. If you are the owner of a sports vehicle, I would recommend you to give it a try.
Rotella T6 Full Synthetic – Ideal Motor Oil For High Mileage Engines
Last, but not the least, in my collection of the best synthetic engine oils, comes the Shell Rotella oil. As the name suggest, this oil is particularly useful for vehicles powered by diesel, whether they be new or old. However, it is not limited to that, and you can use it for vehicles powered by other types of fuel as well. Let me tell you the specifications first.
Low-ash Additive technology
Excellent low-temperature flow
Exceeds diesel engine application
To start off with, yes this too is completely synthetic oil. Pure synthetic oil produces better results as opposed to a blend. This means that the base oil is a synthetic blend and not a high-carbon petroleum product. This helps it adjust to the situation while you are driving. Further, the product guarantees durability and enhances the engine protection. The car oil is mostly low-ash. This ensures a bit of extra mileage and helps to improve the functionality of the car engine.
Secondly, the additive used is low ash. Apart from that, the level of phosphorus and sulfur is low as well. That means that operating the car becomes smoother than before. Moreover, my favorite feature is that you don’t need to spend as much effort on the maintenance either. This further ensures a low emission level with reduced carbon content. So, if you, like me, look for oils that have reduced emission levels, I would suggest this one, purely on that basis. Besides, the additives ensure a low deposit content and low accumulation of dirt or debris. The heat resistant anti-breakdown feature protects the engine itself.
It has a cold-start viscosity feature as well. You don’t need to worry about warming up your oil, even in the coldest of weathers. This can ensure a smooth engine start even at -30F. Actually, among all the mentioned oils, this is a unique feature. This ties up with the low-temperature flow that ensures that the long lasting engine oil remains runny in all kinds of weather conditions, while in the expensive engine.
If you want the maximum benefit from this oil, I would recommend that you try it out on your diesel vehicle.
As a con, I would advise against using it for gear motors. The consistency is too runny to be used with that kind of motor.
Low carbon level
Low phosphorus and sulfur
Reliable in extremes of temperature
Protects against oil breakdown
Cannot be used in gear motors
Even though I placed it last, this is my second favorite on this list. And that’s purely because of the larger number of unique features it offers. Very few oils work that well in -30F as this one does. I was impressed with the emission level, and the idea of a low additive content appealed to me because of its pro-environment features.
That said, you can try it out if it suits your engine type. If not, I am sure other products would. But honestly, it is one the best synthetic engine oils that you can ever use.
Among all the available options that all claim to be the best full synthetic engine oil, it can be grueling to decide what exactly your vehicle needs. Apart from the different varieties of full synthetic oils themselves, there are specific qualities you should look out for in the oil you choose. I will start with the varieties. You can purchase full synthetic oils or a blend.
Full synthetic oil, of course, as the name suggests, is of the purest kind. It is developed through a chemical processing of the essential crude oil against the distillation process used to mineral oils. These are more consistent in its molecular proportions and have more stable qualities.
Semi-synthetics on the other hand, again, are what they are phrased to be. They are made through blending mineral oil with 30% synthetic oil. These are significantly less expensive and yet serve almost the same purpose as the purer kinds.
Next, we come to the criteria that I think is required while choosing your oil.
The first one is viscosity or the consistency of the oil you choose. This is not that simple, because as I explained earlier, the original consistency may vary according to the climate you drive in. This is marked by XW-XX. ‘W’ stands for winter and the digits after ‘W’ indicates the lowest temperature till which the oil can retain its original flow before it begins to thicken.
Next are additives. More additives mean better resistance to sludge formation, leaks and dirt accumulation in the engine itself. These come in several types. Detergents clean out the rust and debris. Anti-wear additives safeguard the metal surface. Foam inhibitors reduce foam formation and retain the oils lubricating properties. Friction modifiers lessen the friction and enhance the mileage. And finally, viscosity index improves preserves the consistency of the oil in high temperatures.
The oil should further be capable of proper lubrication of the engine components. It should lower the fuel economy as well.
Benefits of Using Good Synthetic Motor Oil
As to why you should prefer to use synthetic engine oil, here it is.
Unlike conventional oils that thicken at a higher temperature, it is easier to pour in. And the reverse is true as well. Conventional oil develops a viscosity at lower temperatures that you won’t find in their full synthetic counterpart. This works not only when you pour in the oil but inside the engine as well.
Temperature fluctuations would not affect the engine oil at any major level. This is because, conventional oils, better termed as mineral oils, have wax in its composition that solidifies at lower temperatures. This element is not present in synthetic oils.
For higher temperatures, on the other hand, the latter is capable of resisting any oxidation and hence the lack of deposits. Not only does the lack of oxidation in synthetic oils make it resistant to extremes of temperature, but it also has a longer life in the engine as well.
It is slightly less prone to forming sludge, definitely beyond what a conventional oil can offer you. Moreover, as a whole, the molecules are less exposed to friction which leads to a cooler working temperature that is better for the health of the car’s engine.
Of course, synthetic oils aren’t the only type, and if it suits you better, you can try out something else as well. However, I found this to be the easiest variety for my car.
A Final Note
As with any product with lots of options, it is very important to know what you are signing up for before you buy. If you were confused, I hope that this review helped you in your quest for the best synthetic motor oil.
With so many options to splurge on, you can go all out and get the right product for your car. As to why you should regularly replace your engine oil, I can list a ton of reasons. The high performance full synthetic oil does the job of life-giving fluid to your vehicle. It cools your engine, lubricates it and keeps it running at all levels. Fresh oil gets rid of the accumulated debris that overused oil turns into gradually. It reduces emissions, fuel consumption and enhances the life of your engine. So I would suggest that you take care and alter your oil and your oil filter on a periodic basis and use only a good engine oil for enhanced performance of your engine.
