Convincing the wife both our vehicles need premature oil changes... 15 minutes
A trip to walmart to get enough oil for 2 changes (both cars)..... $130
Swing in the walmart deli for a pretzel.... $3
Trip to the Audi dealer for a OEM "Langzeitfilter" for the car.... $14
Being able to sleep at night knowing Ive reduced the risk of sludge build up....
Priceless.

The 2 mile drive is not good, but the 5 minute warm up is where you get a lot of moisture and unburned fuel past the rings. Start it and drive it normally right away. Auto-RX will help your engine more than most. Maybe that sludge cleaner will clean out the easy stuff, but you'll still have a lot of carbon deposit buildup on your ring groves, then allowing to more blow-by which creates more sludge. ARX will dissolve those deposits allowing your rings to function properly again.
