Three pumps seems to do the job for me on most of the GM models we service to reset it. One other note concerning the oil service life indicator and other lights on your GM vehicle when equipt with onstar. If you have Onstar it monitors your vehicle and will send you a email when you need a oil change as well as other servicing needed lights or check engine lights. The bad part of this is GM knows exactly how long any light has been on via onstar and some bad dealers are trying to use this as yet another way to deny warranty claims. One of my good customers is fighting GM over this right now because his DPF (Diesel Particulate Filter) has gone bad and while he did change his oil as recomended he did not always reset his engine oil service message, so they are blaming it on not changing the oil properly and trying to deny the claim and so far it is working for them.
