That is low. You should call Nissan and complain about the dealership reusing the drained oil. If this was recent, I would change it out quick. Their containers are typically filthy. Also, find another dealership.....Had an engine oil leak on my 17 Titan SV that turned out to be the oil pan gasket, and yes they are silicone and i would like to know why. Dealership said is was a common issue... Worse part is that they put the old oil (7,000 miles on the oil) back into the truck because warranty will not cover the oil change. Anybody else experience this?
