hi Scotty, I have a 2003 dodge ram 1500 with the 5.7 HEMI. I took it down Saturday to have the oil changed, they asked me if I would like an oil flush. I asked what that entailed; they fill it full of kerosene. I said not at this time. First can that really be done and second is that a good idea?

I would only use a name brand oil flush product, and even then, only if I knew the engine has been neglected and is full of sludge.
