Depends on the year which you fail to list.
Let me put it another way before you erase my answer. Nissan recommends that you use 5w30 or 10w30 on ALL NISSAN SENTRAS made between 1995 and 2012. Not sure pre 1995 but expect it to be the same.
Medium grade
10W-30
It is important to use the right type of motor oil in a car to keep the car performing well. A 1999 Nissan Sentra GXE uses 5w-30 or 10w-30 engine oil.
The oil capacity of a Nissan Sentra 1.6L is 5 quarts. This includes the oil within the oil pan and the oil filter.
5w30
The 2004 Nissan Sentra 1.8L take 5w - 30
A transmission oil change for a 2007 Nissan Sentra 2.0 costs about $700.
The location is engine specific. Which model Sentra do you have and which engine does it have?
A Nissan Sentra with the 2.5l engine holds 4.5 quarts of oil. When changing oil, keep checking the dipstick to keep from over filling.
5w-30
3.5 qts with oil filter
2 7/8 quarts. just make it and even 3 quarts.
