Last Sunday (03/04/12) was “oil change” day. I wanted to get the “factory fill” oil from the engine out. Remember, this engine had only 8 miles!
Changing oil on an Ecotec is a breeze. These engines have a cartridge type filter, inside a housing in the block with a screw-on cap. The “nut” on the cap is right large but you can get a special socket to fit the nut. Since the oil drains back into the block, when you take the cap off there is no oil spill. This is great.
Honest, it takes longer to jack the car up and let it rest on jackstands than it takes to change oil. I have been buying GM filters but they are kinda crappy – I rather buy a premium filter. They are a little more expensive, but IMHO they are worth it. As I do with all my other cars, the only oil used is Mobil1 synthetic. The stuff is not cheap, but this has worked flawlessly for me through the years. This is the way to go.
