Mixing oil viscosities? open can of worms

That's kind of like saying you would prefer 50-50 sea salt and regular salt.
It'll make so little difference in anything it wouldn't even be worth the time it takes.

Unless you just want something to do, then...

I say use the 20-50 and be happy also. :-)

Tech857 has a valid question, but then it really doesn't matter does it?
Either it's so low that 20-50 can't save it, or it needs more help than thicker oil.


OH, almost forgot your can of worms. :D
