its responses like this that make me think my next wagon will be maybe a... Volvo..Youre talking about your 87 300E? no not likely going to get 30..but many report the 26-28 range and the math? no we dont do ANY math with a reserve light but wait till we fill up and then factor the MPG based on gallons taken which is always subject to error.

how you know the gallons consumed at the reserve flash is beyond any science other than the crystal ball. What I know is it went from 260 to 290 and counting, still not on. You dissagree fine, its my car, I was there. If you have no insight dont offer it.
