Find out what grade of oil the dealer used. these cars are very sensitive to oil grades. too thin an oil will cause low pressure. When you say low how low? What is the gauge reading?

The dealer used oil 10-40 and then now they changed 20-50. The gauge reads nearly zero. And When the engine is warm the engine will make some noise like clap clap clap. Can you help me ?

is there still oil in it? maybe they didnt top it up enough?

Maybe its the old sensor problem - the Nissan electric sensor is very unreliable after only 3 or 4 years. It reads correctly when oil is cold but drops like a stone when warm. The sensor wears out in the range its mostly sitting in. You can check it with a mechanical guage - think you will find that is all thats wrong.

Maybe yeah i'll try to check it out But the machine also make funny sound. so i really dun have a clue about it

If by funny sound you mean Knock knock knock then you have trouble

Ya it makes that knock knock knock sound like no oil going to the engine so can anyone help me thank you

it sounds like the engine has run one or more big end bearings. That is very serious and expensive and if it is Nissan locally who rebuilt the engine I think you need to give the problem back to them.

Ok thank you I'll try to ask them about that
