Depends how much you drive. Try this:

# years to recoup cost = (cost of swap) * (current mileage) / [(price of gas) * (miles driven per year) * (% increase in mileage with OD)].

Eg. I get 10mpg and gas is ~$3/gal here. I probably drive about 2000 miles a year. Assuming a 30% increase in mileage (which some companies claim), and a $1500 swap, it would take me 1500*10/(3*2000*0.3) = 8.3 yrs. Hmmm... that 3.08 rear end is sounding better... assume a 15% mileage increase and a $300 swap: 300*10/(3*2000*0.15) = 3 1/3 years. OK, who's got a spare 3.08 rear?
