If you are looking for the best engine oil we are here to help you out. If you want to keep your engine running smoothly no matter the conditions it’s important to know what oil to use. On-time services and oil changes will make your engine last longer for many years.

Benefits of Engine Oil

Engine Performance

Oil is an essential fluid to keep your engine running at peak performance. Without oil the mechanical components of the engine will not properly function. These components work tightly together to efficiently deliver power to the wheels. Oil helps lubricate the friction between these components. 

Operation In Extreme Temperatures

Using the correct fluid on your car will help in peak operation during extreme weather. Antifreeze is a mixture of water and antifreeze and it will help the car operate no matter the temperature. Same goes for the oil. It never freezes but it will become more thick and that will make it harder for the oil pump to flow oil into the engine components.

Better Fuel Economy

Automakers have been seeking for one thing in the past 70 or more years of mechanical engineering. Efficiency is the word. An engine running efficiently will consume less oil and run better leading to a better fuel economy.


Using the right oil for your engine will prevent the unnecessary oil changes. Truck can go up to 100.000Km with a single oil change. For better understanding read your oil interval change requirement.

Types of Engine Oil 

When it comes to choosing oil you will face different types of oils. Which one is the best for your engine and when to change your oil?

High-Mileage Oil

High mileage oil contains additives and seal enhancers that reduce leaks. High mileage oil is commonly used in heavy-duty vehicles. Trucks are designed to have oil changed every 75.000 miles but your car isn’t. The high mileage oil contains detergents that claim that are designed to remove sludge from engines. This type of oil is best recommended for high mileage cars that have been well maintained. This oil will help mitigate more engine wear. 

Synthetic Blend

Synthetic blend motor oil uses a mixture of synthetic and conventional base oils for added resistance to oxidation. It is recommended that you change this oil every 8 to 9 thousand miles. The synthetic oil blend is better than conventional oil, helps protect the engine from wear and works better in high temperatures compared to conventional oil. The synthetic blend oil gives some of the synthetic oil features at a lower price. 

Full-Synthetic Oil

Full-Synthetic Oil is commonly used in newers cars. This type of oil is best for keeping the engine clean. The fully synthetic oil is the most expensive and commonly used in cars with high RPMs and tons of car mods. A fully synthetic oil is not derived from crude oil, but rather chemical compounds. Fully synthetic oil in simpler terms in thinner. It lasts longer and performs better in both low and high temperatures. 

Engine Oil Specificationsmechanic replacing the best motor oil

Before we mention the best oil you can put on your car you first need to know more about the key features of the oil. We often see different motor oil brands label their oil bottles in 5W-30,10W-140 but what does that really mean?

These numbers are the oil metric. Oils are measured based on how thick or thin they flow. The term for measuring this is called viscosity. Viscosity is a measure of a fluid’s resistance to flow. In winter cold temperatures require the oil to be thin in order to start. The first number you will see before W is how your oil acts in winter.

W stands for winter, your oil will act as a 5 weight oil. The next number after W “30” is your oil weight when operating in normal or high temperatures. However, oil does not transform from thick to thin. In fact, it acts like it to ensure engine performance.

What To Consider When Buying Motor Oil

Choosing the right motor oil is very important for your car engine. It is best recommended for you to stick with the owner’s manual. That is the oil that will work the best with your car’s engine. But as a car starts to get older you want to protect it better. A good tip is to stick with the same brand as recommended on the owner’s manual but as your miles keep rolling you want to choose a thicker oil.

As high miles cars will start to wear you will see greater oil consumption if you use thin oil. Always make sure to check the API rating. API is the authority that checks the quality of oil and if it meets the minimum requirements based on several tests. In Europe, you would see TUV as the badge of quality. Make sure your oil meets the highest standards.

Also, make sure to have a talk with your mechanic based on the current engine state. If the engine is worn and needs to be redone any type of oil will not make any difference. Despite listening to your mechanic will help you prevent engine failure by interval oil changes and usage of the correct oil.

It is also recommended that you change the oil filter together with the new oil. You also get discounts from choosing a pack of oil and filter set. If you are looking for a premium oil filter that will last at most 5000 miles then you should look at a Purolator oil filter.
