Mr.X brought oil bottle several days ago and i want to ask him "Did you remember" or "Do you remember" when you bring the oil bottle. Can someone tell me which one is correct in this case?
Did Mr. X bring with him a bottle of oil or just the container, i.e. an oil bottle? Or did he purchase, or buy, the bottle?
"Do you remember when you brought the oil bottle?" means that he carried the bottle with him some place. The sentence as it stands is a bit awkward, and probably needs clarification: "Do you remember when you brought the bottle of oil to my house last week? What brand was it?"
"Do you remember when you bought the oil bottle?" is asking Mr. X if he remembers when he purchased the bottle. You are asking him how long ago it was, or on what day.
