For some time now my 2000 Bonneville SSEi has been using roughly 16 ounces of coolant every 4-5 weeks. There is no leak or dripping anywhere. The only thing I can think of is it's because I make a lot of short trips under 5 miles in length. I try to make sure the car gets warmed up, but this time of year it's tough when work is only .9 miles away. Don't feel much like driving around on my way home.
From my experience 16 ounces is excessive for a 4-5 week period. Everything else is fine with it and the temperature never gets away from where it should be.
Any thoughts?
