I would sure appreciate it if you would document and report back exactly how much you use, how long you drive with it in the crankcase, and whether it stops the leaks or has any adverse effects. You've been really great about sharing your experiences of the first few months with your Crossfire since November. It's a '07 with 87K miles on it? It will help everyone if you give a follow-up report.

But...my tendency is to listen to an expert like Needswings, i.e., "100% recommend against it".

Good luck and have a Happy New Year!
