Subject:Re: Changing oil: Hot, Lukewarm, or Cold

Always have wanted the oil reasonably hot, but not scalding.  Maybe as you
guys say, warm, might be better.  I use nitrile gloves, like real techs do,
to protect myself, though I used to just let it get all over my hand.  And
even though the Waterboxer filter is at an angle, I still make a mess.  But
it is better than my Toyota Prius, with the filter up between other parts
in an area where my hand just barely fits.  It would be ok on a lift, but
the best I can do is to raise the vehicle 1&7/8" with a timber.  Lets me
fit under, but still cumbersome.  The camper is wonderful in that regard,
with the high clearance and easy access!

Related, slightly:  Is it ok to mix synthetic and conventional oils?  I
used to see oils that claimed to be half and half, and wondered if I might
get by with that, but home mixed.
