Synthetic oil leak???

[Jim@StreetLethalPerfrmnce]

i have a 2005 6.0....my bed plate and or pan is seeping, just enough to color the dirt on the engine black, it does not run or make it to the ground. i do have a rear main leaking (of course, easier fix than the pan), does not make it to the ground when it sits, (probably would if ran for a half hour in the same spot).....so i want some input from experience here, i am considering going to a synthtic 5w/40 for winter. at 30f degrees the ***** dont wanna run worth a damm till its ran for 10 minutes. i have dino 15w40 with rev-x in it now. im thinking the syn 5w40 with rev x will help a lot....or would i be better off with dino 5w40 with rev x??? i just dont want leaks all over the place!!!

The synthetic isn't going to leak more but the lighter weight oil would.

5w-40 will be better than 15w-40 in all temp situations. rev-x can be used in either oil.

is the synthetic worth the extra bills??
