may be I can try the "Lucas System Treatment" next fill up...
If you have a blow-by issue "fresh" oil won't really do much about it.

Are you talking about the Lucas fuel system cleaner, or the oil additive? Although I seriously doubt there would be an issue after only 14k miles, carbon deposits can cause the compression rings to stick in the piston and cause blow-by. If that is the case the fuel system cleaner could help. I stress could because there is no guarantee it would help even if that is the problem, and I doubt you have that big of a carbon deposit problem after 14k miles. But the fuel system cleaner won't hurt.

As far as the oil additive is concerned I'm not a fan of Lucas oil stabilizer. It is extremely thick and is unnecessary. It also isn't likely to do anything for a blow-by issue.
