[AT] STP

[John Hall]

You may want to consider adding some Lucas oil/additive. I run it in my 
F-150 to keep the lifters from clicking on start up. I also added it once to 
a F-12 that needed the crank replaced--wouldn't maintain oil pressure when 
hot at idle and had already had bearings changed. Obviously it will only buy 
some time in a working machine and the severe cold up your way could be a 
problem on start up.
