Re: Oil Consumption

If you really want to see oil consumption,get a JK or a minivan with a 3.8

That would be the bigger problem than the oil consumption!

You are correct. It has been in my experience that with Mopar vehicles that I have owned in the past no matter how many times I would top it off it would always burn down to where it was in the safe zone and stop. However, when I tried topping off one my vehicles off (while in Germany and driving on the autobahn) with synthetic oil the oil didn't burn down…it expanded and caused the valve cover to leak. Once I drained the oil down to where it was in the middle of the crossed hatched area (AKA: Safe Zone) the valve cover stopped leaking and the oil remained at that level until I changed it. If you are in the Safe Zone leave it alone is my motto when it comes to Oil levels.

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.

This is borderline comical. They put this in to cover their ass.

Both my 4.7HO and 4.0 don't leak or burn a drop of oil between 3k OCIs. From what I can surmise, the Hemi isn't an oil burner either so when one has excessive consumption, clearly something is wrong.

I'd tolerate 1/2 qt every oil change. Anything greater than that and I'd give Chryco an earful.

Re: Oil Consumption

I agree with Xmonger...I've got the HO, and have had an XJ with a 4.0 and a TJ with a 4.0. Never burnt oil at all, and the 4.0's were both over 100k.

Re: Oil Consumption

I agree,they should not and usually do not use any oil.My sons 4.0 liter just turned 200,000 miles and it uses nothing between oil changes.And that's @ 5000 miles or so.My other son has 175,000-same story.My 4.7 uses nothing and it has 78,000.Wife's 3.7 uses nothing-its around 36000.They do just put that to cover their asses and/or save warranty$$$

1qt / 1000 miles is considered and industry average and no manufacturer will do anything if the consumption is at or less than that.

It likely will slow down as the engine runs in but it could be caused by the crankcase ventilation system which is the likely culprit if you see a quick loss in the first half of the change cycle then a leveling off in the last half. That uneven consumption indicates it's not being burned off but forced out by improper pressure in the ventilation system and once it reaches a certain level the pressures balance out.

I would mention it and ask them to check the crankcase ventilation hoses / valves for kinks or blockage but if you pull the plugs and they are clean the engine is probably not burning it and I don't think you have anything to worry about.

Re: Oil Consumption

I noticed a similar issue this weekend with my V6 Overland. I had changed the oil right around the 500 mile mark (yeah, yeah, whatever, it made me feel better) and was very careful to get the oil level right in the middle of the "safe" zone. I am confident it was there because this was the first oil change, so I was very careful. (I admit I could practically do an oil change on my old Tahoe blindfolded I'd done it so many times, but since this was the first time with the GC, I double checked EVERYTHING.) Anyway, I've got about 1600 miles on it now and decided to check the oil level and lo and behold it was down a half quart. I figure I'll keep an eye on it and if it's still doing it at the 5000 mile mark, maybe I'll mention it to the service advisor. I doubt they could/would do anything, but I was very surprised.

Re: Oil Consumption

I have checked the oil level in my Hemi and it is higher on the stick after running then after it's sits overnight. When I checked it in the morning it was lower on the stick. I would usually expect the opposite, I checked my wife's and hers is the same way.

Re: Oil Consumption

My new Overland Hemi has 2600 miles on it and I just added the first quart of oil. It got a pretty easy break in, but still consumed a full quart of oil in just 2600 miles. I know sometimes new engines during breakin use a little extra oil, but I have to say I'm a little disappointed. This is my first Chrysler product after 40 years of GM ownership and I never added a quart of oil between 5000 mile oil changes on a GM motor.
