When I had my Honda Civic, running (4) 3k OCIs on Royal Purple made my internals look brand new. Granted, this was on a 98 Civic with a D16Y7 that was purchased by my father brand new, oil changed every 3K with Castrol GTX until I switched er off to Royal Purple.
Perhaps a switch to Royal Purple Duralec 15W40 may help?
Diesel guys, again, feel free to correct me if I'm wrong...
Interesting, how bad was the Civic when you started the Royal Purple and how did you observe the improvement?
It's amazing that continual 3K OCI with Castrol GTX made the engine that bad to start with. My 96 Accord has had much longer OCI with different oils and it looks pretty decent.
