im doing a oil change tomorrow on my jeep.... i never am to skeptical on what oil i use.. is there any really good brands for my 2004 jeep grand cherokee 4.6 h.o.
its 4.7 not 4.6 anyway me and my dad both use. Castrol Syntec full synthetic. it depends on how far you drive or how many miles are on your jeep most likely the any top brand 10w-30 will be fine.
