Bosch D+ D3410 off my 2002 F150, 3,414 miles/13 month interval. Lots of short trips with a rare highway trip thrown in here and there. Put on a Mobil 1 M1-210A filter this time and added 1 qt QSUD 0w-20 and 5 qts PP 0w-20. With the short tripping this truck does, I plan on a ~3,000 mile interval again. I keep debated never doing another oil change on the truck since I use a qt of oil every 1,200-1,500 miles. I have a Fram Ultra on my shelf, maybe next year I will put that one on and just do a 4 year run without changing the oil or filter, just keep adding oil.
