i've heard of some people having trouble with synthetics, simply because they're usually thinner viscosity. on an old engine with a lot of wear, the tolerances might be too wide on the gaskets and seals and such to keep the thinner oil where it belongs.

i have no idea what this means.
unless you mean the engine is 'using' oil and smoking now?
if so, i'd just switch to Rotella 15w-40 and not worry about it.
