Jason,
If I could to real math.... Never mind. Math was not my subject. I have not had a math class since 10th grade geometry in 1975. I never had Algebra II, or Trig, or Calc, but...
I think what you are talking about can be figured by taking miles for a given tank, divided by total miles, to get a percentage that tank represents of the total miles. Multiply that number by the mpg for that tank, and you get X. Do the equation again for another tank and you get X1, and again for another tank and you get X2, and again for another tank and you get X3.... Add X, X1, X2, X3, etc together, and you get an mpg for the total number of miles entered.
Am I making any sense? It frightens me to think I might be. Don't ask me how I came up with this. I don't know.

Known: Lifetime MPG, Lifetime Miles, Starting MPG, Starting Miles, Tank Miles
Need: Tank MPG
This may be really easy, but at 1:45 after all I've been doing on this thing... can't think! Thanks.
