The take holds 11 gals of diesel and 44 gals of grease. Stock this engine is 220ish HP, and 440ish torque. With the mods I'd be happy with 300HP and 500-600 TQ. Combine that with the fuel economy and this murders anything reliable that runs on gas that I can put under the hood. My 300 HP small block I had in there only got 10mpg if I feathered the gas. I've been given mpg numbers for this engine ranging from 15 to 23. I'll find out when I start driving it. As far as your euro diesels, they are 10 times the daily driver that this will be. I tried to talk my wife into a TDI, but she wanted a civic. I will always have my gasoline gulping tire frying chevelle.
