FAQ What type of oil is Jeep Liberty 3.7l

What engine oil do you use in your KJ?

The Avenger / Sebring engines are different from the 3.7 in the KJ. The KJ likes a thinner oil.I believe it only utilizes 5 PSI at idle or something similar.

What kind of oil did you use in 2006?

Our ’06 is due for its first oil change since we bought it. The oil filler cap says 5w-30, and the owner’s manual says to use 5w-30 for all climates. My ’03 on the other hand has NO recommendations on the oil filler cap and the owner’s manual has a chart as to what weight oil to use.

What is the difference between 5W30 and 10W30 oil?

The main difference between 5w-30 and 10w-30 is that the 5w-30 will start to lubricate critical engine parts sooner than 10w-30 will at any ambient temp, both have the exact same “hot” viscosity of 30w oil. Stick with 5w-30 all year round and you should not have any problems, no need for 10w-30.
