in the State of Washington the difference in cost for reg vs. Prem. is 10 cents. or $1.40 per 14 gal of gas. The cost of a top end valve repair is about $2,500.
If you purchase 1785 fillups at 14 gal. you can break even in cost.
Mileage
The 2004 V8 is rated by Lincoln as 17 City 23 Highway.
My LS has 17K miles and I see 17 to 19 city and 23 to 25 highway (75 mph)
The least mileage (14 city) was after trying 89 oct fuel. The rattling was not music to my ears either. :slam
