I just stumbled across a thread on BITOG about new Auto RX instructions. The poster said that Frank said, I believe, that the instructions would change by recommending a longer dino rinse phase. Very interesting, could you enlighten us Frank? Here is a link to the thread...
When the "Group 111 Oils' were introduced the application ratios of Auto-Rx were experimented with and we saw that longer cleaning mileage coupeled with longer rinse miles provided a greater benefit. Auto-Rx has to consider a multitude of factors before changing application instructions. Sme of these is the customer who reads nothing and get his Auto-Rx Application from a message board- Others who will modify there oil with the latest oil additive rave.
Of course at the first sign of trouble it is attributed to Auto-Rx when in fact some new solvent or synthetic additive posted by the products salesperson masquerading as one of the boys was bought and used as Auto-Rx is to slow. (I made it slow for initial applications when Auto-Rx was first introduced )
My all time favorite is the poster who did not think his oil was dirty enough so he added a solvent product and guess what his oil turned black, now he is happy.
We are not quite ready to announce the new applications. Nice thing about Auto-Rx is you can adapt it to new applications and not waste your money. The other nice thing is Auto-Rx can remove the "crud' some put in there engine before permant damage is done.
I've always used Mobil 1 5w-30, but switched to Castrol GTX 5w-30 for both the clean and the rinse phases. I'm about 950 miles into the rinse phase, should I extend it?

I believe extending the rinse phase (and probably the cleaning phase also) is a good idea. I've been experimenting with this myself, running clean and rinse phases as long as normal change intervals for cheap mineral oil, that is about 3-4000 miles. Have had no problems with this, but a potential problem would be oil filter clogging; customer must watch their oil lamp carefully. Do not know the real benefits with this application, but it is very convenient Arx-ing with the same intervals as normal oil change, just "fill and forget", no extra costs from oil/filter.
