here is a fuel tip that i use daily. i check crude oil commodity prices. if crude closes up 2.00 a barrel, then i know that within 48 hours it will hit the pumps at an approx increase of 8 cents per gal. i paid $2.99 a gal for diesel tues 10/30/07 following these tips. the price rose the next day to $3.05 breifly then to $3.09. so at 123 gal at $2.99 vs $ 3.09 is a saving of & 12.30 this can add up over a year into big bucks. also you can do the reverse. if prices fall & you dont need fuel, waiting a day can save you also. when prices spike to 3-4 dollars a barrel my wife & i fill up all the vehicles we own not just the big truck. i have been doing this for over 8 years & use these charts to trade commodities also. just click on the link then oil & energy then crude oil nymex. the close if in red in down if in green then it's an increase. you can do the math on more gallons for more savings. hope this is helpful to someone.
