The word synthetic has brought about a lot of confusion with regard to its actual meaning in the motor oil industry. Ideally, this should define motor oil that is made of purely a non-petroleum base oil but this is not how it works.
However, what you need to know is that synthetic oil has better lubrication properties than conventional oil and a good option in this type is the 5W30.
Basically, the number before W shows the oil viscosity at low engine temperature (on startup), with a lower number signifying lower viscosity or thinner oil. The number after W (30 in this case) shows the viscosity of the oil at the normal operating temperature.
To avoid all these complexities, here is a review of the best 5W30 synthetic oils in the market, from which you can pick the most ideal one for your engine.

On top of this, the oil increases your engine’s fuel efficiency while also providing better protection against wear and tear in the engine, as well as other forms of corrosion inside.
Another benefit is that you get quite a lot of oil in the pack, which is sold in a 5-quart bottle (160 ounces), and this is probably enough for doing a complete oil change in your car.
4. Valvoline VV955-6PK – Large Quantity 5W30 Synthetic Oil
If you have a big gas-powered truck that requires a lot of oil when doing the oil change, then this VV955-6PK from Valvoline should be your go-to option. This is because the product is packed in 1-quart (32-ounce) bottles, but comes as a 6-pack, which means you get a total of 192 ounces.
Though expensive, this is quite a lot of oil and is enough for large engines, and if you have a small gas engine, then you will have plenty remaining for your next oil change.
After this oil change, this 5W30 synthetic oil will maintain your engine’s fuel efficiency, all while meeting the performance requirements for supercharged, turbocharged and naturally aspirated engines in passenger cars running on the North American continent.
The oil also provides high-temperature protection when the engine is under high performance, and also low-temperature protection by improving the oil flow, especially during startup.
Another benefit your engine gets is sludge and varnish protection, which leads to improved engine cleanliness on the inside.
5. Mobil 1 94001 – Official 5W30 Synthetic Oil for Nascar
Mobil 1’s 94001 is an advanced synthetic motor oil that is used as the official motor oil in the Nascar world due to its high-performance characteristics.

This 5W30 synthetic oil is specifically designed for extended performance and is actually guaranteed to give you 20,000 miles between oil changes.
The oil achieves this kind of performance because it is engineered with fluid titanium technology, which offers maximum strength under pressure. This reduces friction on metal-to-metal contact across a wide range of driving speeds, leading to extended performance.
Apart from this, the product is 3 times as viscous as other synthetic oils, which gives an extended performance, while sludge plus varnish formation is reduced so as to improve the engine’s response.
With this kind of capability, the oil is recommended for extreme applications such as high-performance driving, racing, towing and hauling, as well as frequent short trips on extremely cold or hot temperature environments.
On the downside, the 1597B1 is designed only for gas engines, but it comes in a 5-quart bottle (160 ounces), which is quite enough for a complete oil change in most gas engines.
7. Mag 1 61790-pk6 – Friction Modified 5W30 Synthetic Oil
Mag 1’s pk6 stands out from the rest due to its FMX friction modifier formulation, which reduced wear-and-tear in the engine by up to 56% more as compared to standard motor oils.
The oil is also highly viscous, which gives better lubrication for improved engine response and better fuel economy, and is formulated with High Phos Retention 2DP for extended performance against wear and tear.
Other features include engine protection from cold temperature wear during startup, compatibility with gas engines only and a quantity of 1 US quart, which is quite a small amount and more bottles may be required for a complete oil change.
8. PurOl Elite Series 4019-01 – Good 5W30 Synthetic Oil
This 100% pure synthetic motor oil is designed to do a lot of performance boosting in your engine, such as improving the fuel efficiency for increased mileage, as well as increased torque and horsepower for improved throttle response.
Apart from this, the oil contains an exclusive additive package, which makes the product an ultimate anti-wear agent, as well as a thermal and shear stabilizer. Combined, these features make this the top-rated 5W30 synthetic oil in our review.
However, the lubricant is only meant for gas engines and it comes in a small 1-quart container.
This lubricant is specifically designed to give longer drain intervals in 4-stroke engines because it has a high resistance to viscosity and thermal breakdown, which leads to extended performance.
The 5-quart oil achieves this because it has a high-tech synthetic oil base that is supported by high-performance additives.
With this formulation, the product promotes an extended use because of the quick lubrication at startup, as well as consistent performance in lubrication on all other operating conditions.
Apart from this, the oil is compatible with both gas and diesel engines, and in both, it helps the engine start and warm-up smoothly, while also resisting thinning at high temperatures. However, the lubricant does not clean the engine.
10. Shell Rotella 550050318-6PK – 5W30 Synthetic Oil for Hauling and Towing Trucks
Shell Rotella’s 550050318 is the most expensive 5W30 synthetic oil in this review but it comes in a large quantity, with six 1-quart bottles that give you a total of 192 ounces of lube for a complete oil change in your gas engine.
However, what stands out most about this oil is that it is designed for gas-powered trucks and SUVs, providing superb protection to their engines when under high performance from hauling and towing trailers.
The lubricant is designed to outperform conventional motor oil during such driving conditions by preventing thinning at high temperatures, thereby maintaining optimal lubrication at all times.
Aside from this, the product also maintains cleanliness inside the engine by preventing the formation of damaging deposits such as sludge and varnish, and this results in improved throttle response and increased power output.
How to Buy the Best 5W30 Synthetic Oil
1. Full Synthetic or Synthetic Oil Blend
Fully synthetic oil has better lubricating properties than oil blends and even though it may come at a high price, this is the best option, especially if you are running your engine at high performance such as when racing, towing or hauling.
However, if you use your car just normally on the highway at normal performance, then you can opt for the synthetic oil blend, which should be more affordable. However, if you can afford it, go for the fully synthetic oil
Compatibility also plays a crucial role in determining the type of oil that you can buy for your car. The main factor to consider here is the fuel type that your car’s engine consumes, which should either be gasoline or diesel.
A safe bet would be to buy the universally compatible oil such as Liqui Moly’s 2038 or the one from Speedol, but you can still go for the specific ones if you are sure about the type of engine that is mounted in your hood.
Failure to adhere to this might cause a non-improvement in performance or even engine damage in the worst-case scenario.
Viscosity can basically be defined as the state of being thick and for motor oil, the thicker the lubricant, the better because it will provide better lubrication to all the internal moving parts, leading to improved longevity of the engine.
Another important factor to check is whether the oil thins out too much at high temperature, thereby reducing its viscosity. If it does, then it might not be very effective when the engine warms up or under high engine performance.
Ideally, the best 5W30 synthetic motor oil should maintain its viscosity or just lose just a bit so as to maintain proper lubrication and protection in both low and high-temperature conditions.
Each kind of 5W30 synthetic oil has its own set of additives that help in solving a certain problem such as preventing oil leaks or preventing deposit build up.
Ultimately, the best 5W30 engine oil should at least do an engine clean up and provide a solution to a problem in your engine, if any. Therefore, always check the included additives before making the purchase.
Brand also plays a huge role in the selection process because it would make more sense to buy from a well-known brand such as Shell than from an unknown company, even if it is more affordable.
Good performance is key in any car engine and the oil you feed in plays a crucial role in determining how well your engine responds normally or under pressure.
With 5W30 synthetic oil being a commonly used lubricant in modern engines, it can be really difficult to pick the best one for your car if you don’t know what to look for.
However, after going through our 5W30 synthetic oil review above, it should be much easier for you to pick the best 5W30 synthetic oil for your car.
