Oil Consumption

What is within normal ranges for a hemi consuming oil?

Sequence of events:

Noticed around 1,500 miles it was a half a quart low. I thought they didn't fill the oil all the way at the factory.

Oil change at 1,500 miles after I got home it was a half a quart low. Topped it off and a 1,000 miles later it is down another half a quart. So basically it is burning a quart of oil every 2,000 miles. This is crazy I have never owned a car that has burned this amount of oil. In fact I have never owned a car that the oil level has ever dropped on the dipstick before.

Is it still breaking in or is it going to continue like this?

Re: Oil Consumption

My Hemi, 45,000 miles, not once has it needed a top-off between services.

Have you noticed it burning any on startup?

Re: Oil Consumption

Exactly I have never had a car burn a drop either. No I haven't noticed any smoke or oil smell. But it is definitely going some where.

Re: Oil Consumption

7 quarts of oil in my 5.7L ends up in the middle of the two marks on the dip stick. The 20 year tech at my dealer said that's normal and don't fill to the top line. He said the excess oil covers more of the crankshaft and will reduce gas mileage and horsepower. I'll go along with him.

Re: Oil Consumption

I have had vehicles burn oil. My old 1992 Saturn SL2 would routinely use a quart every 3000 miles; this was normal for that engine and as long as you kept it topped up, it would run forever. My 2002 Nissan Sentra SE-R used about a quart every 2000 miles (the early QR25s had an issue with a catalytic converter breaking up and having the catalyst getting sucked back into the chambers), and that's one of the reasons why I ended up trading it off. It just always felt like something was about to go wrong (and at 80K, stuff started to). My '05 Accord, my '08 Patriot- never used a drop.

Some engines just use more than others. Mechanics and dealers generally won't bother trying to find the source unless it gets to being more than a quart every 1000 miles or the oil smoke becomes a real problem (even at 1qt/1k miles, it usually isn't smoking much); the cost of the time to track down and fix the problem is way more than the cost of the oil.

Re: Oil Consumption

My 06 eats up a quart every 4k. I change my mobil 1 every 6k. So I keep a spare quart around.

Re: Oil Consumption

Well I am going to mention it to the dealer next time I am in for service. I do not want to worry about checking oil every 1,000K and filling it between changes. I do not see myself keeping this jeep very long if it continues. This is just not something a modern, brand new engine should be doing. I would understand if had 100K on it.

Re: Oil Consumption

I'd do exactly that.

Burning that amount isn't normal for this particular engine, I don't care what anyone says.

You shouldn't be checking the oil every 1k on a 100k beater let along a brand new WK2. Complain and get it documented asap.

Exactly my point. I did post on another users under the general section who noticed their was consuming the same amount of oil. It appears mine is slowing down now, but I will keep my eye on it.

If you look at an owners manual,you might see this-
At Each Stop for Fuel
  • Check the engine oil level about 5 minutes after a fully warmed engine is shut off. Checking the oil level while the vehicle is on level ground will improve the accuracy of the oil level reading. Add oil only when the level is at or below the ADD or MIN mark.
  • Check the windshield washer solvent and add if required.
Also complaining to Chrysler will get you nowhere.Their official stance is this- Case Number999926737 Vehicle IssueSuspected excessive engine oil consumption, burns oil, uses oil, with no leaks found.;Applies to most Chrysler Corporation models unless otherwise specified. Excessive engine oil usage or consumption suspected.System or ComponentAbnormal Behavior / Function,Consumption / Oil Level Low But No Leak;Customer Concern (No DTCs);Engine OilRecommendationNORMAL OIL CONSUMPTION: Below are industry standards for normal engine oil consumption: Mileage below 50,000: Normal oil consumption is one quart for each 1,000 miles driven. Mileage above 50,000: Normal oil consumption is one quart for each 750 miles driven. TEST TO DETERMINE ENGINE OIL CONSUMPTION: Operate engine to normal operating temperature. Fill engine oil precisely to FULL mark on dip stick gauge. Use paint pen to mark the engine oil drain plug to prevent tampering. Check engine oil level after 1.000 miles driven. Refer to normal engine oil consumption listed above. POSSIBLE CAUSES FOR EXCESSIVE ENGINE OIL CONSUMPTION: PCV OR CCV SYSTEM: Check the crankcase ventilation system for proper operation. Oil may accumulate in the throttle body or intake manifold. Also, rocker arm lubrication oil flow returns to oil pan through drainback holes in top of cylinder head. Plugged or restricted oil drainback holes may contribute to excessive oil in crankcase ventilation system. SPARK PLUGS: Examine all spark plugs to identify the affected cylinder(s). Spark plug on the affected cylinder(s) will usually be fouled or wet with engine oil. VALVE GUIDES AND VALVE STEM SEALS: Inspect valve guides on the affected cylinder(s). Replace valve stem seals on the affected cylinder(s). PISTON RINGS: Check piston rings on the affected cylinder(s). Piston rings may be too tight / worn / broken / carbon build up in the oil control ring. CYLINDER WALL: Examine the cylinder wall on the affected cylinder(s). Cylinder wall may be severely scuffed. Perform hone procedure on the cylinder wall or replace cylinder block / short engine assembly as required.
