I burn a tank every 3 days. Sorry but I don't have an accurate measuring system. I was putting a quart in once a week, now I'm putting a quart in every other week or a little longer.

Temps may very well have an impact on oil consumption. Mebbe this summer I'll take it back to OEM & record precise consumption rates as I put it back on one step at a time (assuming that I don't use some Rotella or SeaFoam before my next oil change.
