They now have a 5qt bottle, and it covers most of their weights. You'll have to check if the 0W40 comes in the 5qt bottle though. I'm not sure.JG - 1/29/2005 10:55 PM
The ring is more than likely the oil drain washer. I do my oil changes with the same oil. On my last change, I installed a fumoto valve so I should never need to change the washer. The price per quart seems way too high, especially since the dealer probably buys by the 55 gallon drum. The cheapest I have purchased is around 4.50 per quart. I wish Mobil 1 would sell in larger containers. The last time I called Mobil, they only sold in quart and 55 gallon drum.
