I just got a bottle of auto-rx and I'm trying it for the first time. I'm not driving much this month and I'm just wondering how well does this stuff clean if the car is just sitting in the driveway?
Aurto-Rx requires the engine to be running. Since you state you drive so infrequently suggest you add the driving miles until you reach suggested mileage for cleaning phase to be over. Auto-Rx is fine sitting still just like your engine oil.
