I have seen guys put a tube into bottom of bottle, sealed at the cap and punch a hole for a blow gun. I can only imagine the mess i would make.
I have a 5 gallon pail and a gear oil pump. I usually buy a gallon at a time.
For as often as I change the gears out, I really should look into something like that. Or maybe it will slow down/stop after the Charger is done. That will likely end up with the quickchange rear diff I have.
