We went with Mobil 1 synthetic and a Fram oil filter.

Definately don't continue with the Fram because they are known to be bad. AC/Delco filters are the best in the business. The interior of the frame is the problem. The use a paper filter that will deteriote and the interior valve will let particals back into the engine. The AC/Delco has a screen and a OEM valve that does not allow junk to flow back. I have read the tests done on filters and Fram is not good, believe me.

We went to Chevy and bought a new oil filter for it. We took out the Fram and put in a new A/C Delco filter. No oil loss. Tomorrow we will take apart the Fram filter to see whats going on.
What about the air cleaner and the fuel filter? What brands?

I am not sure about the fuel filter but I wouldn't doubt Fram is subpar in this as well.
For air filter the AC/Delco has been known to be among the best in protecting your engine. Test after test it has been proven to trap more dirt than any other. Wix brand are supposed to also be good with oil and air.
I thought I saved it but I can't find a recent lab test showing the AC/Delco air filter superior to all others. Not only is it very good at flowing air but it traps more partical than any other.

When it comes to oil filters or oil all major brands will be fine unless you push the milage between oil changes. I myself change the oil in my car at around 2,500 give or take a 100 miles. I use whatever is on sale, Fram, Pennzoil etc. It only makes a difference if you go above the 3,000 miles intervals. When I had valve cover gaskets replaced on my 94 cavalier the engine looked as good as new with no build-up of junk in it, and probably have used fram filters more than any other brand. The same thing with oil I always use Castrol GTX 5-30. If you change your oil at 3,000 miles or less your wasting money on synthetic oil. Synthetic oil is for people who go 4-5 thousand bettween oil changes. If Fram was so bad they would have been either re-worked or pulled from the market by now.

They are bad compared to the better ones but not bad enough to pull from the market.

You are making a blanket statement about spin-on filters. You can't compare a spin-on to a cartridge. I also like AC/Delco, but people have to reallize the Ecotec engines don't even use spin-on oil filters. I've used AC/Delco, Hengst, Fram, and Purolator on my Ecotoecs. I still like the AC/Delco the best. It seems better made and the pleats don't "shred".

That wasn't a blanket statement it was simple statement relating to can type filters. Actually I forgot the Cobalt has a cartridge filter but even so I would stick with AC/Delco or Wix when replacing any filter. The AC/Delco filters perform tops in evaluations.

Almost ALL spin on auto oil filters use paper as the filter medium. What is unusual about the Fram filters is that Fram uses paper for the end caps. Other brands have metal end caps that the pleated paper is seated in, and plastisol is used to provide a seal. Fram uses a dense, felt-like paper instead of steel to make the end caps, and they use glue to achieve the seal.
