From NPR News, This is ALL THINGS CONSIDERED. I'm Melissa Block.
If you drive a car you already know gas prices are up. The national average for regular gas has risen to nearly 3.75 a gallon. It's typical for prices to jump near the end of winter when refineries turned to different formulas they use during the summer, to reduce smog.
But as NPR's Jeff Brady reports, this year, the rise in prices is happening earlier.
JEFF BRADY, BYLINE: At the Oil Price Information Service, executive editor Denton Cinquegrana has been watching those prices closely.
DENTON CINQUEGRANA: Retail prices have gone up for each of the last 33 or so days, dating back to about January 17th.
BRADY: Cinquegrana says he doesn't see prices going above $4 a gallon like they did in the summer of 2008. He says as refineries switch to summer blends, they shut down units and do maintenance. Traders worry there won't be enough supply so they start bidding up prices; this year that's happening a few weeks earlier than typical.
Cinquegrana says one reason is refiners are catching up on maintenance and repair work they weren't able to do late last year because of Superstorm Sandy.

BRADY: At an Exxon station just outside Philadelphia, regular gas is selling for just under $3.78 a gallon. Billy Boyland is putting $20 worth into his Honda Accord.
BILLY BOYLAND: I've been looking around for the past four stations and this was the cheapest one.
BRADY: So 3.78, that's a bargain?
BOYLAND: Yeah, well.
BRADY: A few pumps over is Nicole Cornwell.
NICOLE CORNWELL: I remember when gas was a dollar-fifty.
BRADY: Cornwell cleans houses and offices for a living, so she drives a lot.
CORNWELL: I got a new car and I got some good gas mileage, so that at least helps.
BRADY: Most analysts believe prices will continue to rise a bit more. Cinquegrana says since the rise started early it may end sooner than typical.
CINQUEGRANA: Gas prices are probably going to be higher at Easter than they are at Memorial Day and Fourth of July.
BRADY: And looking out a few years, the U.S. Department of Energy projects lower gas prices primarily because world crude oil prices are expected to decline. The department predicts regular gas will average $3.55 cents a gallon overall this year. And next year, federal energy forecasters believe the average will fall to $3.39 cents.
