Regardless of what truck you pick, If you plan to keep your truck for a long time, IDGAF what your manual says, change the oil every 5k. These 10-15k intervals are rearing their ugly heads after your warranty runs out.
Dirty little secret: extended oil change intervals are a result of manufacturers wanting to avoid carbon footprint/enviromnmental penalties. They’ve done the math, and spec high-quality, low viscosity synthetic oils to exceed CAFE standards and tout the benefits of fewer oil changes over the life of the vehicle. All of this, of course, is fine, when you consider the “life of the vehicle” to be at the end of your powertrain warranty.
