Mark does oil change at home (after about 47,296 more oil changes, the garage will pay for itself lol)
He likes synthetic and is paying 4-5 dollars a qt to get it. His friend likes regular oil but has had trouble finding it to buy, so he got synthetic. Yes, synthetic can go longer between changes.
We are returning today from a short trip and our son has been home. Our power went out on Friday afternoon, in the court of five house, everyone else got restored in a few hours as normal, it seems our house may have never gotten restored and they are working in the court this morning. I think we'll be trashing some food.
We are very surprised at the length of this outage and the fact our house alone is left. So we didn't take any proactive steps like adding ice to the fridge on Friday/Saturday.
