Oil for summer and Auto-Rx

[coopns]

I have a 02 Grand Caravan and going to start a Auto-Rx treatment. Any oil recommendations 5w or 10w, can't use synthetic right?

Thanks.

I used Chevron Supreme 5W30 for the two bottle treatment in my dad's '98 Dodge van.

Use whatever the owner's manual says. When do you expect the 3,500 mile clean and rinse phases to be completed?

Also what weight synthetic are you presently using?

Not using a synthetic now, but would like to switch when rx is complete. Cleaning phase will be completed approx. Oct.

After you finish the ARX program run Mobil 1 5w30 and a Purolator Pure One filter. Awsome combination for that engine.
