My fun bike, which rarely goes out in bad weather has white lightning lube on it. Stays clean, works nicely.

My commute/utility bikes get tri-flow in the summer, and 30wt motor oil in the winter (when it is wet). I usually clean and lube the drive train of one of my bikes each week, and I put on an average of 150 miles total per week.

I clean and dry the chain, then put one drop on each link, and I don't end up using that much lube at all I would guess that I end up buying a bottle of lube, either tri-flow or white lightning once every 6 months. How are you lubing your chain that you are using so much, or are you lubing every bike in the fleet every week?
