Survey Says: Get the Royal Purple out of Your Diff

[kayger12]

Got my Blackstone report back on my 16k mile differential sample using Royal Purple Max Gear.

All I can say is, I'm glad that Derek mentioned his sister's diff failure after switching to RP and also posted up some links pointing to suspect performance of RP in the diff.

As you can see from the report below, my metal numbers were through the roof. And while Blackstone wasn't alarmist over the numbers, I think there is major reason for concern with those kind of numbers.

Fortunately, the RP Synchromax in my Getrag performed much better. I'll post that info up in a separate thread.

Yeah, glad I had that plan of changing out at 15k. Also thankful for Derek's timing that kicked me in the ass to do it.

At least we have solid data now.

My pleasure... or displeasure, lol.

Interesting statement made in reference to these results posted by a member over at BITOG:

Not much knowledge on gear oil from me, but my conclusion is that you did right by switching to Red Line.

RP could have washed out wear metals that were left behind by the original fill. Synthetic oil can do that in an engine, and it might do it in a rear end.

My trans report with the Synchromax was actually good.
