Has anyone here installed "Auto-RX" in a noisy engine? - PeachParts Mercedes-Benz Forum

Thanks Jim. Well, I have ordered "auto-rx" and it came the other day.... I finally got around to put it in the engine this evening when I got home from work. As recommended, I installed a new MB oil filter to catch all of the debris that it is supposed to displace.... I will drive the 1000-1500 miles and see what happens. As mentioned, my 269K Mercedes, surprisingly has NO leaks, NO oil burning and NO smoking and I hope use of this does not start any of that. I do however have a "noisy" and "clacky" engine. The lifters (especially on the passenger side), will clack and chatter and I have what sounds like a knock, but only between 1500-1900 rpms on acceleration.

If it smooths out my engine, I guess I will move onto why my car is occasionally missing.... perhaps a vacuum leak, bad fuel relay, plug wires, etc.

I will not start driving the car until Monday... so the "work/cleaning" should begin then.

Since my car holds 8.5 quarts of oil, I had to pour in a entire bottle and part of another. It said 16 oz. for 8 quarts of oil and each bottle is 12 oz., so I poured only about 1/3 of the 2nd bottle in it. The rest will go into the tranny of my truck, which probably needs the tranny cleaned, since it has 103K.

One of the problems to my car was an intermittant 'tick-tick' from one lifter on the right side of the engine. Unfortunately it wasn't due to a broken oil tube (Menu#19).

Started using Auto-RX (ARX) and have been using it since. It cleaned all of the 100K+ miles worth of sludge and most of the varnish from the engine although it's not marketed to clean varnish. ARX does remove sludge amazingly and I continue to use it now in the maintenance mode. My engine has never run better and is quiet.

Here's a link showing what ARX did to a '93 Nissan 240SX. The results were amazing especially the increase in compression for all cylinders.
