Best to carry out an oil consumption test.

(ie so many miles per litre of oil)

That is the only way to get an informed answer to your question.

What is the mileage of the car?

The plugs look fine.

It's done 109k. Can I take readings from the dipstick or will I need to drain the oil?

Its 2004 DE its pretty bad have to top up after every longer journey. I dont know how much exactly per mileage but is noticeable.

Hi Guys,

I have an issue with high oil consumption on my 350z. I have done compression test and all 6 cylinders are around 185psi on the 6 stroke during test so it seems compression is fine. I dont have a compressor to do leak down test which would be more accurate. Car drives well but I am worrying it might be problem with rings or valve seals. I took pictures of the spark plugs (do they look like car is burning oil?). I wonder if anyone here had similar issue and is able to give me some advice?
