Fearing drivers might rush gas stations to fill their tanks before prices jump even higher after 15-cents-a-gallon gas taxes come back at midnight, state and consumer groups officials have the same message - don't top it off unless you really need to.
Because retailers schedule deliveries based on how much gas drivers buy on average, a rush to the pump would only deplete already tight supplies and push prices higher.
Drivers might well be jittery after seeing prices go up by 20 cents over the last few days and as much as 33 cents from a week ago.
Consumers shouldn't get slammed with the returning taxes immediately.
State Revenue Commissioner Bart Graham says many stations shouldn't pass on the tax increase to consumers when the clock strikes midnight because they have bought that gas tax-free.
