I can tell you my team believes so much in the Auto-RX product we had the guys in the graphics shop give Frank some "sponsor" room under the hood. We all are absolutely convinced Auto-RX provides us maximum efficiencies and that equates to RWHP.

2004 GTO - 600+ hp Muscle Car
from Nelson Performance

I just wanted to share my teams experience utilizing this product in our muscle/strip car(s)... We run a 04 GTO putting well over 600 RWHP to the ground....We have utilized AutoRX for sometime now...at the suggestion of my tuner... (I was not a fan of additives at all)...however on his insistence we begin with the AutoRX..and followed the AutoRX maintenance program in the race car....we quickly realized an additional 8-10 RWHP and more importantly cooler engine temps....this is directly attributed to the AutoRX cleaning the internals and allowing the oil to lubricate more efficiently IMHO. We now have the new 402 iron block in and are getting ready with the new setup looking for the high 9 second 1/4 mile.....you can bet I'll have AutoRX in that race engine going down the track... I am convinced this product provides a much more efficient environment for our lubes to do a better job on the internals resulting in more HP/Lower Temps and quicker engine spool up...

Our UOA's [Used Oil Analysis] with AutoRX never have reflected any viscosity thinning. In my humble opinion in a high performance engine or any engine for that matter you are running a risk of damaged internals putting anything in that thins the oil. This is one great product and I feel the performance and efficiency enhancements are maybe buried or overlooked.
