What is the residue left behind in the oil pan after using RP? I've never noticed this with Redline or Gibbs, at least not much. This "fallout" is thick and takes some doing to remove, kind of like a paste. Any ideas?

What color is the paste tried to call you tonight..

Ed Wright · 10-30-2010, 10:16 PM

Wade, I use it and have never seen that.

I have had that myself with RP, But I always had good luck with it,so I never worried, my bearings always looked good on my stocker w/RP #9.Changed oil every 40 runs.

Are you sure that it's not leftovers from your assembly lube?

Alan Roehrich · 10-31-2010, 09:36 AM

It can also be "fallout" from the racing fuel, and condensation. I found it in one of ours, that had never seen anything but Joe Gibbs. The engine was actually in decent shape, the bearings looked okay, but it had well over 200 passes on it and it was dead tired.

Billy, in this instance, I'm sure it is not. I have had both engines apart after the break in period and a couple of races for inspection. I cleaned out the residue each time. After running both engines again, I found the same thing. At first I thought it may be some of the Comp lifter additive, but it does this without it, too. The bearings do look perfect in both engines. I wonder how early this is occuring and how much protection the oil still has after this seperates and lands in the pan.....

Wade, It may not apply to your situation, but I have seen the black paste in a circle track engine after about 500 miles when using the 10-30 Gibbs. I was told the paste was moly, but I did not verify that. I switched to another oil that made more hp on the pump after freshening that motor up, and have not got it back yet to see if it produced any paste.

An engine shop I used to work for saved some of the used RP, after sitting a while a black film would form at the bottom of the jug, not sure if it is the same black paste you are referring to.

Rick, I have noticed the same thing when I saved some "light weight" RP also. A blackish-gray film formed in the bottom of the clear jug.

Wade, let me give u my 2 cents as i have run a oil company for the last 15 yrs and have
extensive lube tech background, what you have going on is additive precipitation, it
happens after running and especially in drag cars because of the hot cold cycling.
Additives are stable at room temp but when subjectided to our radical temp swings
will fall out of suspention. Break in lube is the worst for this as its heavily fortified with
all the good anti wear extreme pressure additives but they do settle out as they are
only semi-soluble.. Besides that i have a idea or two that will help break-in and all
out performance. P.M. me and we can discuss it...
