Why does my 2002 Chrysler Town & Country consume so much oil?

Why would this vehicle use 14 quarts of oil on only a 1400 mile trip?

My car has 130000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
There are quite a few possibilities when it comes to oil consumption. But with this amount of usage, it should be fairly simple to figure out. It is either leaking it or burning it. There is no other way for oil to be used.

If the oil is leaking out, you should be able to look underneath the car and see a lot of oil. If this is the case, I recommend booking and appointment with one of our technicians to figure out where it is leaking from. Locating oil leaks can be difficult and it requires a significant amount of experience to become good at it. For this reason, I am not going to attempt to direct you on how to do so. I recommend having an oil/fluid leak inspection if you see a lot of oil underneath your car.

The other possibility is the motor is burning oil. There is a caveat to this though. For a motor to burn 14 quarts in 1400 miles, it would clearly have smoke coming out the tail pipe. The causes of this are likely to be rings or valve stem seals. If it is piston rings, or a problem with the piston itself, there will be smoke present at all times while the car is running. If it is the valve stem seals, you will most likely only see smoke when you let off the throttle, or under light load conditions. Either way, these two failures will require a large repair to fix. I recommend an oil level is low inspection to help you figure this out

Good luck!

Excessive oil consumption is the consumption or loss of oil at a rate that is faster than “normal.” What`s normal depends on the specific engine, as each one will have its own recommended change interval and may burn oil at different rates compared to other engines.
Engine Oil

5W-30 (Below 38) – SAE 5W-30 is preferred.

The oil capacity on the Mini-Cooper is only 4.2 quarts. If it burns one quart of oil every 750 miles, you can see that you`re going to run out of oil before your next oil change. Make sure you check your oil level every week. You don`t want to take the chance that it will burn up all the oil and ruin your engine.

Oil consumption is sometimes caused by mechanical problems. Seals and gasket, the bearings, cylinders, ring grooves, connecting rods can be worn or damaged. Cylinders that were not honed properly when the engine was built (or rebuilt), incorrect installation of the piston ring, or other improperly installed parts.
Most car engines are designed to handle 5w20 oil because this type of oil flows well when the engine reaches its operating temperature of 212 degrees. If 5w30 oil is used, the engine will encounter much more resistance at this stage which is not good for it.

Burning oil is often the result of worn-out parts. For example, worn valve seals and/or piston rings could lead to your car burning oil. Both valve seals and piston rings work to keep engine oil out of the combustion chamber.
Oil viscosity is thinner when it`s hot, so it drains more quickly and completely out of the engine than when it`s cold.
In other words, make sure you don`t put a measly 3.6 liters of engine oil in the oil tank when your Town and Country needs at least 5.6 liters to run.

lost all oil pressure, replaced the oil pump, low oil sensor, oil pressure sensor, oil pan gasket,
ANSWER : The fuel pump will not stay on if you loose oil pressure. This is why it is shutting off. The loss of oil pressure may be from bad crankshaft bearings or camshaft bearings. The engine oil pan should be removed and the oil pump needs to be checked to ensure that you put in the pick up tube seal to the pump and connected the pump to the block. Then remove at least one main bearing cap and inspect the bearings for excessive wear and crankshaft damage. If you need some help with this, consider YourMechanic, as a certified technician can help diagnose the issue with your oil pressure firsthand and help you fix it accordingly.

Oil consumption. Burning oil. Oil light turns up on idle.
ANSWER : Hi there, thanks for writing in. The valve stem seals are the most common cause of this on your engine. When they fail, it requires that the cylinder heads be removed and rebuilt to fix it. The piston rings can also cause this but they are not as common. Unfortunately there is not anything, not even heavier oil that will fix this. You will need to have the heads rebuilt.

After changing leaky valve cover gaskets and oil, I’m getting a rattle under cover and oil light and buzzer is now on 2000 Chrysler Town and Country
ANSWER : Hello. If you are getting this light and noise then you have low oil pressure. I would drain the oil and change the filter as it is possible that you got a bad oil filter. If the problem persists then you may have a bad oil pump. This needs to be checked so that you do not have any engine damage.

car burning too much oil and can’t find where it’s going
ANSWER : The engine is sucking it in most likely. The oil control rings are bad or the intake valves are leaking. You should have a mechanic check the intake PCV system to see if there is a problem. After the diagnosis of your leakage, a certified mechanic can make necessary repairs.

How much to replace oil gaskets on a 1998 Dodge Dakota V8 Magnum 4WD
ANSWER : Hello – oil leaks can be simple – valve cover gasket drooling all over the plugs/coils/wires, etc. or sneaky. A leaky front crankshaft seal will slobber oil all over the bottom of the truck. A leaking rear main crankshaft seal, which can also occur with a blocked crankcase ventilation system, will also spray oil underneath, but not show as a drip in your driveway – pretty-much only occurs while driving. I recommend a oil leak inspection to first determine when the oil is leaking from, performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

Oil still leaking after I changed oil filter
ANSWER : Unless there is an imperfection (e.g., serious pitting or irregularities) on the engine mounting base for the filter gasket, the leak is probably not at the filter. There are other adjacent potential leak spots such as the oil pan gasket, oil pressure sending unit and so forth. If the leak is significant at all, merely thoroughly cleaning the suspect area and running the engine while looking for the leak should be sufficient. If you still can’t find the leak origin, a UV visible dye can be added to the engine oil which will then make the leak point visible using a detection light. If you want these steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an oil leak diagnostic and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
