I still say if you think Ford is wrong you're an idiot for waiting 5k miles for an oil change. You should always change the oil with every tank of gas--more is better! In fact, maybe every day is the right amount. All we know is that the manufacturer is wrong and their numbers are just made up...
Diesel engines always tend to be heavier (to stand up to the really high pressures) and if your payload isn't limited by the engine that extra weight simply cuts into your capacity. I think there's still some place for diesel in the US for a little while longer, but (IMO) in anything less than a...
Nope, it has 1510lb payload vs 1860lb on the ranger. (2x2 in both cases) You'll get more payload with the V-6 on the colorado, but still a couple hundred pounds less than the ranger. You do theoretically get 200lb more trailer tow on the diesel, but I'm skeptical of how realistic that is given...
