So my wife's 2009 matrix had a warranty update recently stating that some vehicles have been experiencing excessive oil consumption. This is after i had to put more than a quart of oil in over the 5000 miles between oil changes. So i take it to the dealer to get a test done. They fill it, seal the cap, and we drive it 1100miles and bring it back. I just got a call back from the dealer and it consumed 3/4 a quart over 1100 miles, but Toyota doesn't consider it excessive unless it's more than a quart. Are you kidding me? Not even my 23year old truck with 212k on the clock that leaks oil consumes that much. Kind of frustrated, no modern car should consume anything close to a quart of oil in 1100miles. Fortunately the dealer said we can have it tested again in 6months...hopefully nothing catastrophic happens in the mean time. Jeez...
