I have a Honda Civic with a ZC engine. It is a DOHC engine - 1.6 liters.
I just finished a double treatment of Auto-RX. I looked through the oil cap and noticed that it started to remove some of the varnish. However, there is still alot of varnish left. There are little areas of clean spots.
I don't suspect the car has a lot sludge as regular oil changes have always been done.
Should I do a 3rd treament of Auto-RX to get rid of the varnish? What should I do?
Any help is much appreciated. Thanks!
