I feel your pain, but go ahead with ARX. My wifes
passat was sludged at 60,000 mi. Almost no oil pressure.I did a standard ARX treatment and drove very carefully. At the end of the rinse, changed to
synthetic, took it back to my independent mechanic.
Oil pressure was within factory specs. Mechanic couldn't believe it. Engine replacement on this car
was $9,000. This stuff does work. If it fixed this
engine, it'll fix anything that will hold together long enough to get through the treatment. GOOD LUCK
