I have a 2002 Sentra GXE with the 1.8L engine. The dipstick handle broke off and I replaced the dipstick with a new one from Nissan (double checked the part number with two dealerships). The replacement dipstick shows the engine to be a quart low after I completed an oil and filter change. The owner's manual and everywhere on the internet states the engine should take just under 3 qts. With 3qts added to the engine, the dipstick shows to be on the "L" mark on the dipstick which is a quart low. A Nissan technician looked up something that said you could add a maximum of 3 1/2 qts to the engine, so I added another 1/2 qt. Now the dipstick shows to be 1/2 way between the "L" and the "H" on the dipstick. I've worked on vehicles for close to 50 years and this is an odd one to me.
