This is one of my good friends trucks, a 2008 Frontier with the 4.0 V6 that just hit 201k miles. he bought it from his dad around 100k miles, its in decent shape and runs excellent. Hes the type of person that doesnt do any kind of maintenance himself, he stays on top of it though, he rather pay me to do it so I'm not complaining. I've done oil changes on it every 6-8k with anything from M1 5W30, to Euro 0W40, along with some Rotella T5 10W30, and mostly M1 HM 10W30. I just changed the original serpentine belt yesterday, which was in great shape for 200k miles. I plan on doing spark plugs, transmission, and rear end fluid next. He plans on keeping this truck till at least 400k . He isnt interested in UOA's. I was thinking either Rotella Multi Vehicle 5W30(which seems hard to find) Castrol 0W40, or M1 HM 10W30 along with a Fram Ultra filter every 8k and call it a day. I've read that the VQ series motors shear the oil pretty badly. So what would yall recommend? His drive to work is 27 miles one way at speeds of 55-70 mph, no red lights,no short tripping.
