Why would I lose coolant while using AC?

When i use my AC ill loose coolant, the oil is black like it should be, no greyish film on the oil fill cap and no bubbles on the dipstick. No smoke in the exhaust and it runs at a consistant temperature (between the O and R in the lettering on the gauge) whether i use AC or not. Three weeks ago i added 3 liters and used my AC the entire trip to and from Wisconsin (about 800 miles total) when i got home I added 1 liter and havent used the AC since and its right where it was after i added it. Theres no spots on the cement where i park and nothing dripping down while the truck is running. I cant for the life of me figure out where it could be going?

Is there a chance that it is just coincidence? I guess the only way to know for sure would be to use the A/C again for a while and see if you lose coolant again.

Do you by chance have the Ranger coolant bypass valve mod on your truck?
