    Where to buy TR55's and Rpyal Purple

    I have a 2000 WS6 with 37,xxx I have a TR cam, the car has been tuned. I am still usung the stock plugs, car sits I rarely drive it. I pulled 2 plugs and they both have alot of carbon on the threads, and the middle are very white (hot) my car has been really rich since the tune. I am wanting to change the plugs and im thinking of going with the NGK TR55's , and Royal Purple. I am currently using Mobile 1, where can i buy this......Thanks

    Mobile is a town in Alabama.
    Mobil1 is far superior to Royal Purple if we are talking engine oil. Why the downgrade? Are you pissed off at your motor?

    TR-55's work well in our cars. I think you can buy them at most parts stores. Stay away from the Barney piss. Like Sarge said, there are several other oils that you should consider: http://www.ls1.com/forums/showpost.p...4&postcount=68

    TR55's are decent.

    AutoLite AR103's seem to be a touch more in the proper heat range for the LS1 though.
