Conventional Oil

Conventional oil was first used to lubricate steam engines back in the 1800s [2]. This engine oil type is extracted from refined crude oil, ideal for vehicles with combustion engines. 

Also, this engine oil is much cheaper than artificial oil and has a higher viscosity level, making it slower to flow and ideal for protecting aging engines.

Full Synthetic Motor Oil

As the name suggests, it has synthetic oil as its base or processed petroleum. If you are on the search for solid labels to go with, you can try Amsoil, Mobil 1, Castrol, or Royal Purple.

This engine oil type and its capacity cost higher than synthetic oil, offering higher working performance and protection. Furthermore, it can help prevent sludge, lower chances of friction, protect against extreme temperatures, and regulate oil breakdown to lower the rate of engine oxidation. 

Synthetic-Blend Oil

The Synthetic-Blend oil is made by combining Conventional Motor oil and Synthetic Motor oil as its base, which is also ideal for Jeep Wrangler. Since this engine oil type and capacity is a mixture of the two, it offers a moderate working performance and is cheaper than synthetic motor oil.

The artificial blend offers almost the same benefits despite the price difference, like preventing the vehicle from engine wear and lasting in extreme conditions. 

High Mileage Motor Oil

Moreover, this type and capacity of Jeep Wrangler oil contain seal enhancers to prevent leaks, resulting in lower oil consumption.

Diesel Oil

One of the most efficient Jeep Wrangler oil types, the Diesel Oil is made from distilled crude oil named petrodiesel or from renewable materials called biodiesel. Nonetheless, the two are ideal for a heavy type vehicle with high capacity like Jeep Wrangler.

It also helps to improve the vehicle operating conditions by maximizing the performance and extending the lifespan of the engine. However, diesel oil can increase the risk of cancer and respiratory-related disease.
