Just wanted to drop you a line. I recently did my first treatment of Auto-Rx in my engine (1997 Honda Accord, 110K miles). Never really had any troubles with the engine (in fact, I was always kind of proud how well it ran due to diligent maintenance), so wasn't sure if I'd experience any noticeable benefit from your product. Well, about 200 miles after the initial treatment, I can say that I've noticed a significant increase in overall smoothness. The engine is simply quieter and my drive much smoother (especially noticeable at start-up) than it's been for a long while. I feel like I have a little more power as well but haven't really measured it to be sure.

So thank you, Frank, for a great product. It's great to find something that truly seems to work. I can't wait to put it in my second treatment and also use it in my transmission next.

Thanks again,

Chuck
