The federal government says proper tire inflation can improve fuel efficiency by 3%, or up to $0.12 per gallon (third item, “Keep Tires Properly Inflated”).
Since July 14, when President Bush lifted the executive ban on offshore drilling, oil prices have fallen from $145 per barrel to $120 – a decline of 17% – and gas prices have fallen from $4.05 to $3.83 per gallon nationwide, a 5.5% decline. (Gas was down to $3.56 where I filled up today.)
There were other factors in the lower oil and gas prices, but the fall in prices should deflate some of the naysaying from Diane Feinstein and others who claim drilling will not effect prices for ten years.
