In my experience, running 50/50 oil and ATF at idle for 20 minutes does
absolutely no harm. Just DON'T DRIVE THE VAN.  I have done this procedure
twice on two different vans. You may check the archives to see if someone
has a better mixture.

The way I look at it, piston speeds, temps, and bearing loads at idle-2,000
rpm (when not pushing the van) are so low, and the viscosity of the oil/ATF
so durable, there is very little to worry about.

Is there any chance that running ATF in the motor might in itself require a
compression check afterwards??  This sounds a bit like a "foxfire" type fix
but I'd like to try it myself if that ATF diluted oil won't do any damage
to
the motor.
