I have a 2001 Jeep with 4.0 engine. I have been using PP for the past few oils changes, normally going to 7500, using an Amsoil Ea filter. I have not done o UOA on the PP yet. Does
anyone feel its worth the extra $$ to go to Ultra? The 5 QT jug of PP at Wallymart is $20 & change. Add about $10 for Ultra. I use 6 Qts so its a little more for me.
