Performing the first oil change in my beloved 165,000 mile Grand Cherokee the other day. Upon removal of the oil cap and shinning a twisty light down in there, there is some deffinate gumming up that was visible. Nothing terminal, but caused me some concern.
I changed the oil from Quaker State 10w30 dino to Valvoline MaxLife Blend 10w30. Will the Synthetic Blend clean it up a little? I have another jug of Full-Synthetic MaxLife ready for its next oil change. Now I'm reading that MaxLife can cause sludging???
What gives?
Should I run this MaxLife blend through this oil change and change to a different oil (Mobil 1, 0w-30 Castrol, Pennzoil Platinum, etc.)? Is there anything that would "clean it out" a little bit better than this for the Full-Syn MaxLife I was going to use next?
I realize that one oil change is not going to undo 14 years of age and use...just wondering if there's something better that I'm not using or haven't thought of.
And if anybody says "cash for clunkers", so help me....
