The change oil soon light finally came on in the Envoy after 11,000 miles. I've previously run a 10,000 mile interval with Mobil 1 and LC and had a good report from Blackstone.
I forgot how evil that filter is. It is mounted above the front sway bar and there is no place for leverage. Add in the warm (hot) oil pan and you make for a pain in the butt filter removal. I had to use a big rubber strap wrench to finally budge it enough to spin it off by hand.
When I grow up and run GM (I expect the call any day now), I'm going to make every engineer and designer change the oil on each one of their designs before they hit production.
