Had my 2023 Frontier for one year now, bought used. Have 20k miles on it now. Dealer and mx schedule says due for diff gear oil change?? Not 4x4, probably will never go off road with me. Most trucks go their whole lives without gear oil changes. Why this truck at only 20k miles? Randy
I own a 2019 Frontier and I am meticulous about service. I inquired from a very reputable source about this issue. He said that if I was towing a trailer consistently or off-roading frequently, 20 -25,000 miles is good. Whereas, with normal driving with only occasional tows or off-roads, he did not feel a need to do it more frequently than 50,000 mi. He also said that if off-roading or towing does occur frequently, it is best to get a breather for the rear axle to reduce the pressure thereby reducing wear. Easy bolt on!
