Would this oil consumption notice worry you?

If you owned one of these Chrysler/Fiat vehicles?

Oil Consumption
The accepted rate of oil consumption for engines used in the vehicles listed above is 0.946 liter (1 qt.) in 3,200 km (2,000 mi) for the 1st 80,467 km (50,000 mi). For vehicles with more then 80,467 km (50,000 mi) the acceptable oil consumption for engines is 0.946 liter (1 qt.) in 1,207 km (750 mi).

CAUTION: This above rate only applies to personal use vehicles, under warranty,
that are driven in a non-aggressive manner and maintained in
accordance with the appropriate maintenance schedule,

CAUTION: This rate does not apply to vehicles that are driven in an aggressive
manner, at high RPM, high speeds, or in a loaded condition (for trucks).
See ‘Causes for Oil Consumption’ below. Oil consumption for vehicles
driven under these conditions will be higher and may include Fleet and
Commercial customers.

Sounds like you might never need to change the oil at the rate you might be topping off your new car...
 
With a 6K mile OCI, one could theoretically be replacing half the oil between changes on an engine with under 50K miles.

Presumably more than that if you drive "aggressively".
 
I think it's quite high in my experience. I've never owned a vehicle that used oil at anywhere near those rates.
 
The worst I've had is from the motor I installed in my Accord. If I drove it hard it easy burned over a quart every 3k. Driven normally it hardly used any oil.

In short, a quart between changes wouldn't concern me at all.

A quart every 2k for your Honda would mean several quarts between changes...

For the 2012 Chryslers, the normal OCI is 8K. If it burned off the oil at the accepted rate of a quart every 2K, you would replace 4 quarts between changes, or 3 quarts and be low a quart at the change.

After 50K miles, at the accepted rate of a quart every 750 miles, it would be one quart per two tanks of fuel...or a heck of a lot of quarts between oil changes...

And the above does not include driving "aggressively", which presumably increases those consumption figures.
 
A quart every 3k...for a motor that was originally designed in the late 80's early 90's. I kept that one on a stick 3k change schedule.

The WRXs are changed every 5k (both consume about a quart between changes), the CR-Z goes by the maintenance indicator (about 8k) and so too will the Acadia.

Anyway, I think even official Subaru literature states a quart every 750-1k miles is acceptable. I don't like the sound of that AT ALL.
 
Not really. Most car makers have those guideline like that. 90% of those engine will not see that kind of consumption, unless the engine is abused and oil change was rarely done.

Oil level needs to be checked by the operator, once in a while.

Way too much oil use. My car uses a quart every 5000 but that is because there is an oil leak on one of the seals.

Burning a quart every 750 is just crazy.
 
As bad as that is, read up on the oil consumption issues with the nissan VQ and VK engines (g35/350z HO 'high rev' motor and all q45/m45/fx45)

Basically, nissan has officially stated that something outrageous like 1 quart per ~1000 miles is considered acceptable oil consumption. So, between a 5000 mile oil interval you could replace all 5 quarts and it still be 'acceptable'.

Even better they don't all do it... Some of them barely use any oil, yet others have to add it every few weeks.

I hate to say this but for years now across several manufacturers 1qt per 1000 miles seems to be the normal guideline for acceptable limit.

The worst case in our household was an Izusu rodeo with the 3.2. With a new PCV valve consumption was about .999 qts per 1000 miles but once the PCV valve had a few months under its belt consumption increased to 1qt per 500 miles.

Despite the oil consumption, that truck ran great throughout the 130K mile we had it. fortunately for my wife, I developed the habit of checking the oil in all my vehicles at every other tanks fill.

In my opinion, it's reasonable when all of a certain engine consumes a bit of oil.. For example, the late 90's cadillac northstars pretty much all drank 1-2 quarts between every 3,000 mile oil change. To me, that is acceptable.

The issue is when you have only some of the engines doing this yet the manufacturer won't do anything for the affected motors.. It proves that there is some problem or difference with these motors which consume too much oil.

Truly, nissan's stance on this has made me decide to never buy a nissan product.
 
Depends on the engine. My current S2000 AP1 basically drinks oil and it's perfectly normal. I put in about 1 qt every 1000mi. My AP2s never burned a drop.

1 qt every 750 - 1000 miles would be high in my view. Best bet if you decide on a car like that would be to check the oil every 3rd or 4th fill up and top off, if needed. On some cars, it is due to internal use and on others, it may be due to small leaks.
 
Just to be clear, the TSB states that this rate of consumption is with normal driving.

So if you pull a trailer, or carry heavy loads, or drive aggressively, or drive at high speeds most of the time, the consumption can be much higher.

I wonder what all this oil burning does to the cats and sensors and to your emissions test?

If the EPA isn't testing for it now, maybe they will.
 
That's one way to boost mpg - just burn some oil and gas to use less gas! Brilliant.

Everyone it seems has rather high allowances for oil burning IMO, but that's ridiculous. My Trailblazer I know cooks some oil (has a crappy PCV design) but it is like a quart, maybe 1.5 quarts every 12k miles at the most (has an OLM and that's when the change light comes on, I use synthetic, 160k miles and going strong).

Different engines have different design parameters. With these engines, this rate of oil consumption wouldn't concern me.

With a different engine, my answer might be different.

It's alarming to me. I wouldn't buy a vehicle with such a disclaimer. Particularly the after 50K miles part.

If I am putting in a quart of oil every other tank of gas, that's not normal.
 
I know the hemis tend to burn a bit of oil, but not that much (mine is nowhere near low by the time to change the oil). It also doesn't say that the engines will burn that much. It says that they won't bother fixing them unless they are.

I'd say this is more to do with bad service policies than bad engines. Mine isn't covered by this notice either. It's both 1 year older (a 2011) and an SRT.
 
My RX-8 (which burned oil by design) consumed @1 quart every 1500 miles. The numbers in the original post seem high to me.

I think Chrysler/Fiat is trying to cover up poor manufacturing tolerances and/or poor design.
