I'm planning on moving on to Castrol Edge 0W40 next change.
Car Bible says:
'If you've been driving around with mineral oil in your engine for years, don't switch to synthetic oil without preparation. Synthetic oils have been known to dislodge the baked-on deposits from mineral oils and leave them floating around your engine - not good. It's wise to use a flushing oil first.'
but then condradicts itself saying that flushing all deposits might cause oil to leak from holes previously protected by the baked on deposits.
So, what to do?
