2004 jeep grand cherokee, 4.0, change oil without filter change,

I have the 4 litre (UK) version of the Jeep Grand Cherokee.
Your oil filter is 'horizontal'?
It's simply because the oil filter isn't 'upright' and doesn't hold oil - think of a coffee mug: A coffee mug standing upright can hold more coffee than a mug lying on its side.

When you start the engine the oil pump shoves oil into the filter. When switched off, the majority of oil finds its way back to the sump because of gravity. Remember that it's an oil filter which receives oil at pressure. It's not an oil container/reservoir. You have nothing to worry about.

most 2004-2007 Cherokees v6 and v8 models only had a strainer on the fuel pump jeep does make a replacement fuels line assembly with a fuel filter

The oil filter housing and the timing cover can all be worked on with engine in car.
For the rear engine seal (rear main seal), the transfer case and transmission will have to be removed to access the seal.
Most of the time, the oil pan can be removed without raising the engine. Check your clearance under there for anything obstructing removal. (I loaned out my Jeep manual and never got it back!) On some cars, engine needs to be raised about 4 inches for pan to clear the oil pickup tube. Don't know about your Jeep.

right use the cheapest diesel oil you can buy and change every 5000miles or theirabouts ,change oil filter every third oil change and the muck and carbon black deposits will not build up causing unnecessary wear on the engine ,Do not use so called long life oils and be dazzled by the publicity or some sales assistant in the auto factor who is on commision ,get the oil from a local supermarket or buy a box of the cheap stuff from a auto shop for a better price and trust me you will not go far wrong

Hello, I am a Jeep technician with 13 years of experience, I would recommend Mopar oil filters and Mobil 1 fully synthetic 5w-30 oil changed at 5000 mile intervals

Not as far as i know. But if u can't get it from top or bottom the skid plate is an easy removal. Hope this helps.

egr valve or a O2 senser

the cheapest you can buy and change it every 5/6000 miles with oil filter change every third oil change

filter is inside the box at the end of the long 4" diameter black varigated hose that runs from the throttle body on the engine to the front of the car. Usually there either clips or screws around the perimeter to remove the top portion to get at the filter, On some it's easier if you remove the hoses from it first.
