Auto-RX

[Drew99GT]

I used the product about 3,000 miles ago, I'm currently on a rinse run with 10w-30 pennz. Before I used the stuff, there was a fairly heavy accumulation of varnish on my dipstick. It is now completely gone, so hopefully other accumulated crud was disolved. It removed the varnish with ease; it just wiped away like regular oil, like it really was liquified. Thought I'd share with ya'll.

Drew - your dipstick is steel. I have come to find that Autorx cleans all metals, but does better at removing varnish color from the cast iron and steel parts than it does from the aluminum. It must have something to do with the porosity of aluminum, and the ease with which aluminum varnishes. Because your dipstick is ferrous metal, like your block, crank and rods, it REALLY cleans up well with autorx. steve
