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

What is your question?

What could be the problem & what would be the fix??? DUHHHHHHHH

What makes this problem better or worse?

Nothing

How long has your 2002 Isuzu Rodeo had this problem?

Since purchased 15 qts of oil ago!
