Car #1 - 2005 Nissan Quest , purchased new,with 60K miles. Check engine light and time chain noise. Stealership said it would be covered by warrenty but won't due to severe engine sludge. They are calling it a "maintenance issue". $2700 for repairs and calling it a patch. $4000 for used low miles engine. $7000 for new engine. I took the car home, changed the oil and filter, then poured my first bottle of ARX today. It may still need timing chain or tensioner work but we will see. There is also a company tech report on this same problem. Plan on the sludge application.
Car #2 - 2002 Ford Explorer Sport Trac, purchased 3 months ago, with 64K miles. Just changed the oil and filter in this car yesterday. Poured in a bottle of ARX this afternoon. The current plan is basic application.
I will be changing the PCV valves in both after a trip to auto parts store.
