'98 S-10 ZR2 Gas Mileage Statistics 
Starting from the first tank of gas I have calculated my MPG numbers 
            on every tank that I have used. Unfortunately I discovered a 
            discrepancy in my fuel mileage numbers stemming from incorrectly 
            printed credit card receipts that I used to record my mileage. As a 
            result I have removed all previous figures and have started over 
            with a more accurate (if you want something done right, do it 
            yourself) method of recording mileage. My truck is factory original 
            with no performance modifications. It has an automatic transmission. 
            I run only 93 octane fuel.

I have added a column in the table above to indicate the driving 
                conditions encountered during each tank of gas. Although I have 
                not indicated where, many of the miles I drive include towing a 
                lightweight personal watercraft trailer.
                Highlighted in green are the best [18.013] and in red the worst 
                [16.017] MPG figures for the current set of data. See the bottom 
                of the table for averages.
                A subject that has been discussed amoung ZR2 owners and that 
                seems to be somewhat mis-understood is the advertised versus 
                actual fuel capacity of our trucks. When I followed a thread on 
                the ZR2 mailing list in the Summer of '98 about this topic I 
                decided to do a little investigating. I spoke with my cousin who 
                is an ASE Certified mechanic and has worked in several major 
                auto manufacturers service departments. Here is a copy of the 
                message that I submitted to the ZR2 list concerning this topic.
