i normally use motor 1 10-30 conventional oil...but my local auto parts dealer were out of them....so i use quarker state 10-30 one....would this effect anything in the car? also do anybody know what grade nissan recommend to put in our cars.....

 

Would be nice if you asked in correct forum. I'll move it for ya. Also try reading either the oil's label or their website.

 

1)No
2)5w-30
