Blowing air through the tank with the hose from the tank to the engine hooked up blows the oil not only out of the tank, it blows it out of the engine, that's where the difference is...

 

ok. its 4 qrts. -1/2 a half qrt.

 

I clear the line from the tank also, and when I do my changes I always end up using exactly 4 quarts and it is right at the full mark of the dipstick.. I was surprised, and every time I change the oil I stop at 3 quarts and go slow just to make sure.

 

i usually only can get about 3 in, then i crank it over some, then the last one goes in smooth.

Good point, I should have said that I stop at 3 quarts, crank till I build enough oil pressure for the light to go out, and then end up adding a full 4th quart.
