I received your Auto RX and have used it in a Mitsubishi Diamante 1996 3.0 Ltr that was given to me by a friend it had severe sludge and oil leaks from the cam and crank seals. I personally replaced these along with the timing kit and fixed these leaks.
The car which had done 230,000 kms also blew smoke on revving, burnt a bit of oil and leaked from the distributor o ring seal.
This car is a bit shabby on presentation but thanks to Auto Rx runs very well, blows no smoke and no longer leaks from the distributor seal after being 2/3 way through the sludge treatment (2 bottles with Dino oil).
The car impressed me so much I have last week bought a 1999 Diamante (Magna Advance) 3.5 ltr which has done 196,000 kms which presents and drives very well, everything works and has no visible sludge issue.
This car is exhibiting exactly the same issue with leaking cam, crank and distributor seals. I have cleaned the engine, cleaned the PCV valve and tube/s and breather tubes. Valve covers have been changed and are no longer leaking.
My question is: would it be best to try Auto RX to fix the seals first this time?
Given that it fixed the distributor seal, this may save me the replacement time and costs.
I use Castrol GTX and would like some advice on whether to use 1 bottle or 2 when using Auto RX for this application as sludge is not visibly present? At what point are the seal leaks likely to subside or stop during such treatments?
Thank you in advance for your assistance and your great product.

Particularly if it was very dirty. Many times heat and combustion gases can cause some wear or even warping. Even some small sctraches can cause the valve to stick or fail to open as readily as optimal. I would just replace it with an OEM part and not an aftermarket replica.
Without the visible load of sludge like on your 1996, I would proceed with a basic engine application. That is running a single bottle in a fresh oil change of GTX. Run it for 2500 to 3000 miles or roughly 2800 to 3400 KM. Many times the leaks will stop during this cleaning phase. Sometimes the leaks stiop during the rinse phase, which is the subsequent oil change with no new ARX added. It is important to stick with Castrol GTX or other conventional motor oil to be successful. If your leaks are severe whereby you have to add make up oil every 500 to 1000 miles, then perhaps the Fast Track would be a better approach. But if not then the single bottle treatment would work best.
