Toohey,
In my opinion so long as you change the filter at the same time, plus drain the oil when it's hot you can't do much better. If you use a flushing oil you are only going to contaminate your new oil with a residual amount of flushing oil. Personally I don't like the fushing oils they can disturb deposits that can circulate doing more harm than good. After the first change the old oil will be
well and truly diluted anyway. My opinions a usual.

Don't worry about swapping brands of oil and flushing in between - but I'd swap the filter as a matter of strict habit. You can even swap between dinosaur and synthetic oils without worrying about a flush. What the heck... you can even mix them!

Sorry but this is the kind of advice that cloggs oil galeries and causes cattastrofic resaults , You can NOT mix oils .
Mixing oils is just as bad as not changing oils, All oils are made to spec. I wont bother going into detail , it would take a ten page email to explain it all

Generally I wouldn't do it Eric - agreed.
I should have better explained myself. After draining the engine from one particular brand of oil, or between swapping from mineral to synthetic - a small amount will obviously stay behind - in some lower oil galleries in the main. When you've drained the best you can there will some of the old stuff left behind when you go to fill up with the new oil. At this point you have a slight mixture. This shouldn't be of too much concern.
I certainly wouldn't go mixing 50:50 or anything!!!!
