My husband is always trying to figure out new ways to keep our vehicles maintained when they are not in use for an extended period of time. My husband is deployed a lot so at least once a year we have a couple of vehicles that go untouched for a few months at a time. He has found a sure fire way to keep his Harley in prime condition but he is changed the product in his vehicle this time around. He found a product containing ethos that hopefully will make him get better gas mileage but also keep his vehicle in prime condition during its non-operation.
