I was just wondering what other people are doing to maintain their 8's internals, keeping it running smooth. I am talking about other stuff that is really not stated in the manual. (other than oil changes, transmission oil, air filters, tire rotation...)

For example there is a thread on Protec R and how you dump 4 oz into your gas tank on fill up to help protect apex seals.

Another is just fuel injector cleaner as BG 44K or some other system.

So my question is do you do any thing else that is a little above the ordinary to show your 8 you love her?
