The basics

Synthetic oil is produced artificially from molecules of chemical compounds with scrupulous care. Synthetic oils have properties that almost resemble attributes of natural oil, thereby enabling them to keep the engines of contemporary vehicles well-oiled. On the other hand, regular or conventional oils are distilled from unrefined petroleum or crude oil, and therefore not as pure as synthetic oils.

Hence the high-quality synthetic oils imply that they’ll be able to protect your engine and keep it running smoothly better than conventional oils.  


Synthetic oils are less susceptible to breaking down in comparison to conventional oils. To be specific, if you use conventional oils, you may have to go for an oil change every 3,500-5,000 miles. By contrast, when you use synthetic oil, you’ll have to change after every 7,000 to 7,500 miles. The best synthetic oil brands for Jeep 4.0 will be useful to apply for a whopping 10,000-15,000 miles.  

Which oil is more suitable in extreme temperatures?

Engines tend to become heated as and when they run regularly. So when you drive in scorching environments, the engine oil tends to disintegrate faster. Synthetic oils break down at a slower rate as they happen to deal with high temperatures more effectively than conventional oils.

Conversely, synthetic oils are designed to flow efficiently in cold temperatures, thus keeping the engine well lubricated. 

Protection from everyday wear and tear

Synthetic oils offer better protection from wear and damage compared to regular oils owing to the former’s superior quality. Additionally, synthetic oils hardly contain any impurities, and therefore check sludge formation, eventually keeping your engine cleaner.

Manufacturer’s specifications

If you own a top-quality vehicle like Jeep 4.0, Mercedes, or Audi, the manufacturer usually recommends you to use synthetic oils.
