Just because they don’t wanna or because they don’t feel like it or what? Is it not “preventative” anymore on batteries that can be checked? My truck has only been serviced at dealer, yet when I checked mine the other day, it was 2 cups low. Seems like an easy check that could possibly ward off much bigger issues.That went the way of gas station attendants checking your oil, washing your windows and asking if you wanted them to pump ethyl or regular.
