Please excuse my earlier message about your EPA, I didn't notice that your 4Runner was 4WD.

the new epa rating on a 1998 4runner is city 16 highway 19 and combined 17. You have it listed as 15 18 16.

I am impressed with your 24mpg, I have only been able to get 22 with my 4runner.

I just ordered my ScanGauge, so I am excited to up my mpg.
