Don't think you will save any $$$ that ficht.  What you save in fuel . . . will cost you in Special Oil, Plugs, and Repairs.   The difference in fuel price for a 80 mile trip with gas at $2.50  2.5mpg = $80  3.5mpg = $57  . . . That's a whopping $25 per trip savings ;)  
 
10 Trips = $250 savings 
20 trips = $500 savings 
 
Unless you are commercial . . . it's very very hard to make the new motor fuel cost benefit equation argument (especially when you have a good reliable motor now).
