Rising oil prices lead to overnight gas price increase
CHICAGO (CBS)-- Filling up your gas tank is getting more expensive.
Prices at the pump jumped again overnight.
Right now, AAA has the national average at $3.68 a gallon.
That's cheap compared to Cook County - where drivers pay an average of $4.23 a gallon.
It's a little better in Will or DuPage County at $4.12 a gallon.
You can blame the increase on a rise in oil prices. We'll be dealing with it for a while.
Experts believe it will go up even more before finally trickling back down.
