    What is the best route to go from converting a 5W/30 conventional oil to a 5W/30 synthetic oil ? I've always heard that synthetic will just start a oil leak if it's been run on conventional motor oil. My 1990 305 V8 has always been fed 5W/30 conventional oil and I'm wondering if a switch to synthetic would be beneficial ? I have 112.096 miles on my truck. :happy:
