Engine Oil: what's best?

Ex-member Ezyboy on here ran magnatec in his supercharged AWD and ended up with spun big-end bearings. He blamed the oil after stripping it down and seeing the damage.

I searched older threads here and quite a few members say good things about the MagnaTec, which makes me feel less terrified, but I won't risk it given MadMagnas advice, above. I'll switch to the Penrite, synthetic over mineral.

I was asking about how to replace the engine oil to get rid of all the MagnaTec. I wouldn't call this engine old given its only got 34ks on it. I don't think I need to flush it with any chemicals though, I'm thinking just a couple of drain and fills should do it, right? The MagNatec has been in there for the past 8000 k's and I don't know what before that.
