Yeah, they are PHUCKED I took mine in for an oil consumption test, they change it and you come in every 1000 miles for a check up, well mine was down to the add mark and tbey said well that is 1 quart low, I said bullshit it takes 2 quarts to fill it from there and then the argument got heated so they said we will pull it over into the shop and add a quart and check it.
So they did and said ohhh yeah it only took one quart.
So I said bulshit we all know it takes 2 to fill it from there. Blah blah I could see the scam unfolding, why not fill it right there in front of me?
Going to take oit to a local Buick dealer an try again before it is off warranty.
Will never buy another GM pickup with THIS engine, we had a ZR-1 that never used any oil andI ran that baby, so I may get the Escalade V with the handbuilt ZR=1 engine. but will wait a few months to see what the maket does with real leadership in charge.
