Is it normal for a 2006 Buick Lacrosse 3.8 liter engine to use a quart of 10w30 oil every 3200 miles?

Answer 1

A GM TSB (technical service bulletin) back in 2006 said that it was not unreasonable for my 2005 Lacrosse 3.8L V6 to consume one (1) quart of oil every 2,000 miles. Mine actually used 1 Qt every 1,300 miles and after fighting the local GM people at the dealership for eight months, they finally replaced the valve guide rod seals under warranty. I had a beautiful new car that disappeared behind a cloud every time you started it up after it had set for several hours. GM said I should have just kept adding oil and driving it...it would run fine for 100,000 miles under those conditions. GM dealerships are hateful when it comes to doing warranty work. Six months after the repair, another dealership had to replace the cat converter (also under warranty) after it failed (engine wouldn't go above idle)...probably from all of that consumed oil running through the exhaust. VW was the best for doing warranty work promptly and with a smile...GM will push you to the brink of assault.
