Hi guys! So am a new frontier owner and so far i like! I changed the engine oil and had a transmission flush, truck is a 2018 v6 crewcab sv, first question is how do i know what diff i have? I believe its a c200 but no sure, second question is what diff oil do you guys recommend? Nissan doesn't sell their diff oil individually, according to them they only have as bulk so what brand u guys recommend? I might tow my mustang 2-3 times a year but thats it. Thanks guys!!
