My husband took our vehicle in for an oil change. On the way home from this oil change, the vehicle died while he was driving it. The mechanic determined that something went wrong during the oil change, and the filter came off, emptying all the oil out. It completely blew the engine. The place that performed the oil change is blaming the filter manufacturer, and not taking any of the blame. They are willing to work with us minimally, but are saying we're lucky they are doing so. We want the cost of the engine replacement, plus a few weeks worth of car rental to be covered by them. They are giving us such a hard time about this, and are not claiming any responsibility for whatever went wrong. Do we talk to a lawyer about this? My husband could have been seriously injured when the car died. I don't know whether to take the little bit the oil change place is offering, or to contact a lawyer ourselves.
