iv got an 02 silverado w an 8.1, and its loseing oil pretty bad

i had a navigator that was burning, not leaking, a quart of oil every 1000 miles. i put in a treatment of heartland oil stop leak or whatever it is exactly (available at quick lubes and such) and i didnt burn one drop after. try it out. it might help you out. if not its not like you spent anything to try and fix it.

Hi. How ya doing?.Does it leaves puddles? Do you notice a smell when you drive down the road? Try this. Get a large pice of card board. Make surd its not the waxy kind,but place it on the ground making sure that its big enuff to allow the ole motor to cover it. Give it a few hours and check it. If theres drips,look up above where there are and so that can narrow down a little closer to where the leak my be. Let me know if this helps. Ok
