How is that s10 getting 25mpg, that's wonderful as new it only got 22 mpg. The 1992 Jeep Cherokee outisde my place last I tested got 10.8 mpg. 6 cylinder mostly metal no airbags. Now the snapper push lawn mower I have that was bought in the early 80s is a better example of what you want. I mowed a half acre with it today and it started up on the first pull. Spark plug, sharp blade, and a motor and it gets beat by my neighbors $3000 rider but Ill save that dollar anyday. Exercise isnt hurting my fat ass. That thing runs better than the Honda motors i thought outran their time.
No one cares, but it started up first pull this year after sitting all winter uncovered in a backyard with small amounts of snow
