This should never happen with regular oil changing espically with synthetic oil.
What you have to remember here is that there IS
a difference of WHEN
it'* safe & not safe for an engine....It'* SAFE
if down on a regular basis since the car was new. It'* UNSAFE
if done on an engine that has very high miles on it!
I've ran synthetic oils in ALL my cars & do do a "Engine Flush" to them every Spring. With synthetic oil, I change it every 7,000 Kms instead of the "dino" 5,000 kms.
