Auto-Rx^® safely removes sludge, dirt, carbon build-up, and other contaminants from engines, transmissions, ring packs, motorcycles, power steering, and differentials (US Patent #6,544,349).

Comment from Customer Rich G: I cracked open my valve covers to swap cams yesterday. The pics below show the valve cover and front cover removed. [Click each photo for a larger view.]

The guys helping me were amazed at how clean it was inside with 107,000 miles on it. I did one full dose of Auto-Rx^® at 40,000 miles two years ago. Since then, I changed my oil every 3,000 miles with Motorcraft semi-synthetic and added the 3-oz. Auto-Rx^® maintenance dose. A little bit of oil pooled in the heads at about 3,200 miles. I went a little over this OCI [oil change interval] since I knew I'd have to change oil after this job.

Auto-Rx^®:

• Is a specially formulated, all-natural metal cleaner designed to thoroughly clean the internals of your engine.
• Restores the vehicle to maximum efficiency.
• Decreases oil consumption.
• Reduces emissions because the ring pack is cleaned and the valves seal better.
• Rejuvenates seals, resulting in reduced or eliminated leaks.
• Replaces the need for oil additives and solvent flushes.
• Enables the motor oil to lubricate parts more effectively.
• Saves turbo bearings by liquefying high-temperature carbon deposits.
• Provides residual lubricity because the cleaned components allow polar bonding of motor oil to components.
• Uses oil as a carrier and liquefies all contaminants to prevent particulates from blocking the oil screen, oil pump, or piston port.
• Is safe for turbo engines.

Good Mileage & Performance without Burning Oil. Thanks for all the information over the phone about Auto-Rx^® and Group III oil... I have been a fan of your product, as it really does work ... I've been using Auto-Rx^® as a maintenance dose since I purchased it at 59k. It has really improved overall engine performance and miles per gallon, and the engine burns no oil. Read More>>

Value for Fuel Costs and Better Mileage. Larry L. in Southern California put forth some testing data on running Auto-Rx^® in a low-mileage, fairly old Honda Civic ... Points to note are: (1) mileage gains; (2) mileage benefits better than cost of product; (3) more efficient combustion and reduced emissions; (4) nice, even compression in all cylinders, leading to (5) strong motor for years to come.

Great Sludge Solution:... I came across Auto-Rx^® and what sold me was that it would dissolve the sludge, not break it up. I purchased my first Auto-Rx^® in 11/09 ...Nearly a year later and three oil change cycles, I no longer had my oil light coming on, ever! ... Thanks for a great solution to engine sludge. I would say to people who have this issue, be patient and keep using it as directed. Auto-Rx^® really worked for me... Read the full story>>

Better Acceleration & Quick Start...After putting a few thousand city-driven miles on my car, I found a marked difference in acceleration and quicker starting. And quieter! I can hardly hear whether it's running or not! I attribute it to a cleaner engine because it is ... free of that awful sludge .... It's reassuring ... to feel like you have a new engine again when the odometer says 100,000.. Read the full story>>
