BinB: I thought you said your 514 was already broken in...wasn't it run for 20 minutes??
Ernie: Mixing oils is not necessarily a bad thing as long as you stay within the same API Service Classification. Basically, within the same API Service Classification, most oils have passed the same Sequence tests to get that Classification. It's not something I recommend, but it won't cause any harm either. You are right on though about being an old wives tale...there seems to be a lot of those around where lubrication is concerned.
Now Mr. Fixit, Bob made that statement in the context of lubrication, not in reference to anyone's mechanical ability. Relax, I couldn't bore a cylinder or mill a head, which I am sure you could very easily. We all have different talents and expertise that's all.
