HI Guys

I have been running fully synthetic Castrol EDGE 5W40 in my 3.5 V6 Gen 3 pajero for about 10k km (or 350 engine hours) and its time for an oil change with filter. Now, do I stick with Castrol EDGE or do I change to delo 400 multigrade? I have heard/read that Castrol sludges up in the motor, or is that only the normal Castrol mineral oils and not the fully synthetics?? :? :?

If I do change, do I flush with some cheaper oil and then put the delo in? Or do I flush with delo, or do I do a straight change? Or is it not worth the hassles down the line.... I have read somewhere that switching from fully synthetic to mineral can cause problems. I have been running with delo 400 Multigrade in my corsa 1.4 club, and have been very impressed with how smooth the engine runs after the change. :)

Any advise would be appreciated!!
