I have to do it sorry. 10000 miles driven in a year. 15 mpg will need 667 gallons of gas I will use the cost I saw today on the way home from work at $3.13/gallon that ='s $2086. 20 mpg same way ='s $1565 I will take my tundra all day, week and year for the extra $10 a week. I waited a long time to buy one and the only regret is that I didn't do it sooner before owning a Ram, F150, and 2500HD Chevy. Good thread by the way
