It is also done in Nm for torque not ltlbs.

Ok guys,doesnt matter anymore,seems like it was all a waste of time.
Like i said,this is a friends car not mine,i never got to look at it and he never mentioned that something could be wrong with it.Today he cecked the oil and looks like it burned almost all of it in 600km so that explains everything except for the fact that he couldnt figure out till now that he had engine problems lol.

Nm is like .76 of a ft/lb so that could explain the difference

Yeah, that is way excessive...
Maybe for an automatic AWD car... 1.32 would be ok, but still.
