I don't know what kind of oil goes in a 2004 dodge stratus 2.7l engine

Technically, the starter is grounded to the engine block. There may be a ground strap that goes from the block to the body, but usually the battery ground cable goes to the block.

hook up a odb and see if you have any coads

Be certain your cooling fan is coming on when the engine starts to get warm. If it is, then the most likely thing is the thermostat is sticking (either not working or only opening partially). Just follow the big hose from the radiator that goes to the top of the engine. It connects to the thermostat. They are cheap and easy to replace -- so, if it was me, I'd just go ahead and replace it. If it doesn't fix the problem, at least it rules out a big contender and there is value in that.

Well, you didn't mention which engine your Sratus is equipped with, so I can't give you any specifics on your engine.
The best thing you can do is change the oil, and when you are done changing the oil, change it again. When you are done changing it again, start over. :) I cannot count all of the engines that I have seen go to an early grave because the oil was not changed regularly. I have customers that regularly go 1000, 2000, or more miles over on their oil changes, then cry the blues when the engine blows up.

If your engine is equipped with a 2.4L engine, you need to make sure the timing belt and related components are replaced when they should be. The service interval is 90,000 miles.
Don't skimp and replace just the belt. Spend the extra money and do it right! The pullies and the water pump that the belt rides on also have the same mileage as the belt and will fail and cause the belt to fail before it would be due again. I have seen several people pay their hard-earned cash to replace the belt only, just to have the tensioner pulley or the water pump fail 10,000 miles later and destroy the new belt and cause severe engine damage.

If you have the 2.7 engine, this is not an issue because it is a chain-driven engine.

For more information on the maintenance of your vehicle, it would be best to read your Owner's Manual.

You are developing low oil pressure at idle this is a common problem with Dodge stratus. If you fail to have it fix you will definetly loose the timing chain and the whole engine

Your dodge should use a 5w-30sae oil.I prefer to use a semi synthetic oil it mixes with conventional oil and provides better break down resistance.

on the pass. side of the car, it hangs down on the backside of the engine

usually 4 to 4.5 qts. this can be found in the owners manual.
