Mixing oils - good or bad?
Discussion
Chaps,
Quickie.
I have a half-empty can of oil, and a new can of a different brand of oil. Both semi-synthetic, both of the same grade (10W40), both reach the same specification in terms of manufacturers ratings and so on.
I need to do an oil change on my car (8v Mk2 Golf GTi). Can I mix these two oils when I refill the engine? Is it a really bad idea, or will they work quite happily when together in the sump?
Oli.

Thanks.
I was planning to mix the two, but given that I can get the semi-stuff cheap, I'll carry on using it. It has been running on this for the last 125K miles, and still is as sweet as, and I don't want to risk it.
And anyway, don't be rude about my "Old Motah"! It may be old, but it's still faster than a pedal bike (which is the alternative!)
