Using tons of oil! About 5 qts every 2K miles! No smoke from the exhaust & no leaks showing on the ground????

Wel, it IS either consuming the oil OR oil is leaking out onto the hi way as vehicle is being driven .. Should see evidence of *oil spotting* on rear of vehicle... Look closely. (Maybe someone is stealing the oil)

It could be a number of things from engine damage to oil leak you not seeing under car yet .. we would how ever like to take a look at it though please give us a call
