the only majoer difference between the way conventionals and synthetics work (i think) is that synthetic just don't leave as much gunk behind. there shouldn't be a problem using a conventional oil, but it will run smoother with a synthetic for longer. about the always having to run synthetics thing, nope, i've had to go back to conventionals a couple times due to the cost of synthetics, no problems with leaky seals or anything like that. the only thing that i've heard that synthetics do to seals is that they "conditions" the seals, but i have no idea what that means. the only place i will not use a synthetic is in the rear diff and that is because Jeff at Eaton told me that the LSD wouldn't operate as well with a synthetic oil.
