Gonna change the oil in my f350 dump truck, should i use the 5w40 recommended for heavy duty use? tow a bobcat a few times a month as well as a dump trailer, and obviously use it as a dump truck often, but i still think the truck has an easy life as far as dump trucks go. i don't work it too hard but if i should use the heavy oil then i will.
Actually, 5/40 would be the better weight year round.
But a little more expensive and for little gain during the summer time. The big issue is cold starting during the winter, and that's where having a thinner synthetic oil would really pay off. Lots of talk about thicker oils for high ambient temperatures, but I agave yet to see a bad UOA with factory specified oil.
The beauty of that 5w/40 synthetic. It is especially valuable to all you northerners in my opinion. It's like super slick water at 70° and up. Your cold weather performance is only a big deal when you first start it, right?
I think the T6 would be a great choice and it's cheaper than the Motorcraft.
Unless there's been a change, I remember the Motorcraft being almost $10 more/gal than the shell.
