Diesel Tips on Ford PSD

I have used Auto-Rx in my 2 Ford PSD's with excellent results. I used it in my 95 PSD and had an oil analysis done prior to using Auto-Rx. The Oxidation and Nitration were very high. I cleaned the engine with Auto-Rx and the next use of oil was Dino. It was Chevron Delo 400 and the oil analysis on that was lower wear metals and lower Oxidation and Nitration and Soot. When I purchased my 01 PSD I did an Auto-Rx clean on it and then changed oil to Mobil Delvac 1300S, a dino oil. On that analysis the wear and Oxy and Nit were so low the lab had to re-run the analysis.

I have seen results of VW TDI's after using the Auto-Rx with the same results. The real benefit to me is the cleaning of the soot that seems to find places to reside until the next oil change and then it goes back in suspension causing wear.

The Auto-Rx will not damage your engine in any way. It is a natural cleaning agent and will slowly clean your engine. That is why I mentioned the HEUI injectors in my engine, they take up to 3000 PSI to activate, and the Auto-RX has no effect on this. It does not change the viscosity of the oil. The only thing is to follow the cleaning instructions for an engine with leaks. I would start with clean dino oil and filter, but not required. The Auto-Rx should help your leaks if the seals are not damaged. If they are, and the leaks don't stop, you will have a clean running engine.

I have put Auto-Rx in a new PSD, mine, new 03 Mazda with 100 miles on it and my own Mazda. No problems. It works as stated, cleaned the engine and now I just use a Maintenance dose. I will probably never have to clean them again at this rate.
