Isn't it kind of dangerous putting liquid into cylinders? I don't know how much clearance there is between the top of the piston and the cylinder head, but if you have too much incompressible liquid, something has to give.

I have been running non synthetic Rotella in all my vehicles for over 10 years now. Honda Goldwing, Volvo VNL 770 with the Volvo 465 D12, my 1999 VX and my 2013 Yamaha FJR 1300. The VX might use a quart in 3000 miles.
