I use only Amsoil which is the best on the market. If you order it from Amsoil, then it's like 6.00 a qt. Close to mobile one.

I also change mine every 3,000 miles. I didn't by a hummer to neglect it. Some say change it 3,000, some 4,000 some 10,000.

The Key is you are using a oil filter that is made of paper and it will break down before the oil will.

So if you run it alot more then 3,000 miles, I would recommending at least replacing the filter at 3-4,000 miles.

Oil change with Amsoil and K&N Filter 45.00
