I have recently bought a 2014 maxima sv with the the 3.5l with about 107,xxx miles on it currently. Im absolutely loving the car but it is in need of some love. I need to do spark plugs but have found a few different answers on what it actually takes and was wondering if someone could set it straight for me. I also need to do a oil change in about 3k miles and have heard a lot about royal purple oil and was wondering if it was worth using on this car? And also my poor baby has never had her cvt fluid changed so I need to do that as well and have heard how crucial it is to use only nissan branded cvt fluid so I was wanting to know do I have to take it to nissan to get it done or can I get that fluid and just do the drain and fill myself

 

royal purple shears very quickly. itll be a 5/20 before you know it. personally i use euro spec 5w40 but i also drive very hard.

spark plugs are easy, remove upper intake, remove coils, plugs, reinstall.

 

This is why I just came here to find out what oil would be best to use for the car. I want whatever will keep the motor running the best the longest because I also am known to have a bit of a lead foot myself.
Im not worried about actually changing the spark plugs just curious as to which spark plugs it actually takes. Thank you for the response though

 

OE plug should be NGK DILKAR7B11 but may be denso FXE22HR11

im partial to NGK in my nissans and denso in toyota.
