Oasis is a very large self-serve car wash that is open 24/7. It also conducts emissions inspections during the day. Change machines are available, and vacuum stations are too. In addition to the self-serve spray wash there is a drive-through wash on the large site. Vending machines for cleaning products and various-sized absorbent paper towels are also on the lot. Washes are cash only. Emissions inspections can be paid with cash, check or credit cards.
