synthetic valvoline
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 you should use depends on the climate you live in. In more mild climates (such as Southern California) the proper viscosity is either 5W30, or just plain old 30W. As far as brand is concerned, I prefer Valvoline conventional, or Royal Purple full-synthetic.
