Hey I have an 88 4.0 Cherokee with 169000 miles and she runs strong but I have noticed that everywhere I go I leave ALOT of oil on the pavement! I was running regular blend ever since i got it at about 167000. I heard that synthetic cleans the engine of unwanted sludge so I decide to add synthetic little by little and now my small leak has gotten massive. Also my oil pressure was schitzo..it went from 70 for a while then to 40 then back and forth between 20 and 40 and now it is on 20. I am 80%sure it is my rear main seal and was wondering if there is anyhthing I can do to at least slow it down. I want to kno if running it with a leak like this is bad beacuse I have to drive from Charlotte NC to Baltimore MD. Any response would help greatly thanks!
