Best Oil for Jeep 4.0 Engine – Top Reviewed Jeep Oil of 2020

Engine oil is like food for your engine. So you need to feed your engine with the best quality food (oil). There are different types of oils available in the market based on different needs. For example, engine oils based upon the warm and cold temperatures. The reason why in the earlier times people used to change oils and their types depending upon the weather was due to single-viscosity or thickness of the oils. 

So, one needed a different oil for winter and a different oil for summer. The lower the W number on oil, the better it functions in cold temperatures, and the higher the W number, the better it performs in the hot temperatures. However, now multi-viscosity oils are available, which contain special additives that help the oil thicken in a hot climate and thin up in cold climates.
