I think If you use good oil and change it about 3000-5000 miles either is fine.
I use conventional Castrol GTX 10w30 in my LQ4 2500HD and change it every 4500 miles.
I use synthetic Redline 10w30 in my LS1 and change it once a year....I drive it less than 3000 miles a year so once a year is fine for synthetic.

so why not put it in them as well.
same reason they rate the corvettes that it has more hp then the trans am & camaro's, so the owners of the corvettes feel like they got more but in reality it's the same. maybe a few more pony because of exhaust but same motor.

one of the main reasons people use synthetic is pretty simple: synthetic contains no fossil fuels/oils, so when/if the oil begins to burn, it wont chemically break down and cause sludge. (resulting in wear, and loss of power) synthetic is known for providing a lot more protection and reducing wear. it's not really a life or death decision, just your preference.
