What oil to use with Auto RX? Also ? about seafoam

[Sixxer]

I purchased a bottle of Auto RX and it says that you should use it with DINO oil. I have signature series amsoil 0w-30 in the car right now. My question is should I wait and change the oil back to dino to do the treatment or go ahead and add the treatment to the amsoil and do the rinse with DINO. Also if I run seafoam through my PCV valve on a 4.0 mustang 2008 will it go to all cylinders? Thanks

Follow the directions of Auto RX to word, there is a reason they tell you not to do it with synthetic oil.

Okay well in that case is regular penzoil with a motorcraft filter okay.

Yes Dino with your motocraft should suffice.

I have used without syn oil and with syn oil. Results definitely better without syn.

Any oil with zero ester content and a new filter. And use 2 bottles Rx and run it 3 times the usual distance.

Suck the seafoam thru the brake booster vacuum line. Very slowly.

Probably because it isn't supposed to be used in car engines at all. It's printing press cleaner. Marvel Mystery Oil does the same thing for a lot less money.

All the ARX boosters will be here in a minute!

Per their biggest, directions are just hooey. Use twice as much for 3 times as long and whatever else exceeds any reasonable extrapolation of the printed instructions!

Oh, and good luck. You'll need it...
