Everyone knows that you need engine oil for your engine. Without the oil, the engine will just run for a few seconds before it seizes up and dies on you. Synthetic engine oil doesn’t breakdown as quickly as conventional motor oil, and it can help prolong the lifespan of your engine. You also rarely get the sludge buildup that often results in the use of standard motor oil. For high-performance engines and even for locations that have extremely warm summers or extremely cold winters, synthetic engine oil is the best option. Below is the list of best synthetic oil you can consider buying.
The Best Synthetic Oil[table id=40 /]
1. Mobil 1 Synthetic Motor Oil 5W-30
Most engines need 4 to 5 quarts of new synthetic engine oil, so this amount is just right. But it’s not the quantity of the oil that’s really important here. It’s quality. It’s among the most popular and most highly regarded synthetic oils in the industry.
In fact, some cars specify that you should use Mobil 1 as your synthetic engine oil. It’s the official motor oil of Nascar, and of McLaren-Honda in F1 racing. It has also been revealed that it’s the best at maintaining low viscosity even in cold temperatures.
This “made in the US” motor oil offers all the advantages you can expect from high-grade synthetic engine oil. With its low-temperature capacity, it helps with quick starts during winter, it boosts fuel economy, and it can prolong the engine lifespan. It prevents sludge build and deposits. It offers improved frictional properties, overall lubrication, and wear protection.
With this, you don’t have to worry when you’re not too religious in your oil-changing habits. Of course, you need to follow the manual recommendations as to how often you should change your motor oil. It holds up very well, so you don’t have to panic when you’re a month or a thousand miles overdue for an oil change.
This works great for all types of car engines, ranging from 20-year old Mercedes Benzes to modern turbocharged engines. The bottle is nicely designed as well, so it’s easy to pour the oil and you can use an empty one to collect your old oil for your next oil change.
What’s more, the price for this is exceedingly low, especially if you go online and buy from the right seller.

2. Valvoline MaxLife SAE 5W-30 782256 High Mileage Motor Oil
Obviously Valvoline is going to be part of this list too. After all, the brand does have a rather renowned history with motor oil. In the very first official automobile race in the US, the winning car used Valvoline motor oil for its engine. In fact, Valvoline founder Dr. John Ellis is considered as the inventor of the motor oil.
This MaxLife variant of the Valvoline motor oil is quite interesting because it’s specially designed for engines with higher mileage. Once you go past 75,000 miles for your engine, it can become a bit of a challenge to keep your car engine working without a glitch. You can improve your chances of that considerably when you make the shift to Valvoline MaxLife. It’s what it’s designed for.
For this purpose, Valvoline uses synthetic motor oil blended with more conventional engine oil. Then you have seal conditioning agents that keep seals from deteriorating plus extra cleaning agents to keep the sludge at bay. The blend also includes innovative friction modifiers so the engine turns smoothly, along with additives that combat engine wear.
So do you want your older car engine to work flawlessly despite its high mileage? If so, then you better make that switch to Valvoline MaxLife.
