Hello, I am writing you with any advise for using your product on my VW passat that is currenty parked in a garage for fear of killing my engine from loss of oil pressure due to the sludge issue in these cars, I feel i'm ahead of the game just for the fact that my car still starts, it also has a little noise . I did a flush with ATF and then with Kerosene to clean out the oil pan and screen. The pressure seems to be fine below the Turbo but oil is not getting to the engine. Should I put the RX in the top and Run for limited time frames to clean out slowly, beacause I'm really cautious about driving it just for the fact that the STOP low oil pressure sign comes on. HELP!!!! I read one of your testimonials regarding the same issue, just being cautous, I am dying to try your product to save me from having to replace my engine or worse yet ,turn in my car.
Well,xxxx, you're kinda in a pickle, but really have little to lose in the process. You've got a car that you cannot use. It might as well be seized.
I would do a 2 bottle treatment. I would also use a lighter than spec'd oil. This is to assure maximum flow through any available passage. Areas of forced circulation are where Auto-Rx performs best. Heat is another requirement. The more "at temp" states you achieve, the faster the process occurs. I'd use a 5w-20 semi-synthetic. This is well below the typical 5w-40 OEM recommendations, but you're not under anything like OEM conditions. I would buy a few cheaper filters for the process. I would idle the engine for as long as practical to mix the sump. Oil warms quickly in the VW/Audi engines due to the oil:coolant heat exchanger coupled with the aluminum head.
If you can manage to drive it, I would naturally advise an extremely conservative posture. I would change the filter @ 500 miles and top up with a 5w-40. You can sustain this indefinitely as the filter will remove anything substantial in size and the oil's detergent and dispersant package will handle the rest. The sump will be somewhat in free fall. If and when the warning light goes out, then is when a change to the spec'd oil would be in order. By that I mean spec'd weight. Rotella 5w-40 is cheap (available at WallMart) and more then durable enough for your engine under all conditions. It doesn't subscribe to the ACEA Euro method of classification, but is robust enough for the service duty.
Again, this not what I would normally consider as a treatment method. Figuring that the alternative is a fortune at VW/Audi; probably in excess of the value of the car, then it might be something to consider.
Naturally I must give you a laundry list of disclaimers due to the risk that's involved. The engine may be rendered null and void already. Hence the aforementioned process is merely a suggested method, having no assurance of functionality, viability, and/or merchantability. Proceed at own risk.

I would not have advised using ATF or Kerosene... but what is done is done. Why do you feel that oil is not getting up to the engine?
In addition to using ARX to restore oil flow you should service the PCV system. It's a compless mess of valves and hoses but if they are plugged up you will never make progress in removing the sludge that has accumulated in your engine.
