Using full synthetic oil in a fresh engine or turbocharger rebuild is a good way to cause premature oil burning and/or turbo leakage. What happens? Full synthetic oil is "to slippery" for new piston rings to handle and the molecules in full synthetic oil are to small filling every void. During the break in process the piston rings need to "seat " by a combination of crankcase pressure pushing the piston rings to the cylinder wall, as they are pushing against the cylinder wall the piston rings need to lightly scuff the crosshatching on the cylinder wall. If full synthetic oil is used during this critical process of ring seating chances are that in the future you will have an engine that consumes oil and or a turbo that leaks oil out of the compressor or exhaust turbine. As a rule of thumb, always use conventional oil with low detergents for the 1st 500 miles of engine/turbo break in.
Don't use full synthetic oil. content media
