I started using Auto-RX in my personal vehicle from the day I started driving at the age of 16. I am now 20 years old and have used Auto-RX in up to seven different vehicles. Starting with my 1990 Nissan Stanza, 2003 Nissan Sentra SER Spec-V, 1997 Pontiac Bonneville, 1993 SR20DET 240sx, and two different 2004 Subaru WRX STis.
In each vehicle I used auto-rx as either preventative maintenance or to help treat a problem, with each vehicle we received amazing results. The Stanza and Bonneville had transmission issues that were cleared up within the treatment amount following the specific instructions on your web page.
In the 240sx, and two STis we used auto-rx as a preventative maintenance item and witnessed a decrease in spool time from the turbochargers (Most likely to cleaning out any oil coking), quicker revs, stronger pulls, and a overall "improved" butt dyno feel.
The Spec-V was a completely different case that received multiple bottles of Auto-RX as the QR25DE engine is known to be a oil consumption engine due to a defect in the precatayltic converter on certain models, after removal of the stock header and replacement with an aftermarket piece I noticed I was having oil consumption of about 1 1\2 quart every 2500-3000 miles. After using auto-rx with the oil burning\sludge usage instructions the oil usage was completely stopped and the engine regained some of its previous reliability.
The transmission on the Spec-V is known also to be notchy and hard to engage, with the use of Auto-RX and high quality transmission fluid I was able to cure the 2nd gear grinding I was encountering and having to deal with, the car was driven by other Spec-V owners and none could believe the smooth engagements my car had, thanks purely to Auto-RX.
On top of all of this in each instance, and each case I've noticed a 2-6 mpg increase acrost the board. Being younger with the price of gasoline today I keep VERY detailed gas logs, during but mostly immediately after the rinse phase I got results of better miles per gallon.
Leave it to me to say that Auto-RX is incredibly effective, and a great cost solution to save money in a time where gas is at a all time high.
Thank you for the great product, and amazing service, quick shipping and awesome forum. Engmus
