Great product, same price as dealer but not enough. I have an 08 Vibe, the same 1.8 liter engine as Matrix and Corolla. Just draining through the plug gave exactly 4 liters, but lowering the pan to clean and/or replace the filter drained another 0.8 or 0.9 liters. Had to go to the dealer, they charged $7.49 a quart. They said around 4.5-5 liters per filter change - depending on how hot it is when you drain it. The hotter, the more comes out.
