Just want to get straightened out here. I have Lube Control and Auto-Rx. I plan to do the full ARX treatment after my next OCI in the Xterra using dino. I will probably switch back to RedLine after the ARX is complete so I would like to know which would be best for maintenance. I have heard that ARX and RL's esters don't get along too well and also that RL does not need LC. I feel the need to do alittle cleaning along the way as this engine probably gets dirtier than I realize, even with the RL. Also what is favored for use with Schaeffer's? I plan to run the #703 in my Maxima. Thanks.
