oil consumption

[Timd32]

Pretty high usage for 1k, my 2010 chevy would eat thru oil it was how they designed the thing, at the end was 2-3 qt in 4k, never burned it or leaked, it just consumed it, it had to go. Always ran good oil and 5k changes. Nothing was going to help that thing.

Found this information only deal.

Could be all that Heavy Agressive Towing you do

A friend of mine who is a high end mercedes tech (one of their top techs in the US) said that these cars have loose rings (on purpose) and they leak on start up and when cold. When they reach temp is when they tighten up. That explains the qt per 2000 miles. But, in my case, not a sudden qt in only 1000 miles.

Perform a leakdown test. This will likely show a high leakdown in the center 2 cylinders (just my guess).



I've got several friends with Toyotas that are plagued with the chronic drinking problem!

My buddy's 06 Dodge minivan has a "continuous oil change" going on since new. It sounds funny when low at over 200K on it... He has had some luck with reducing consumption by replacing the PCV valve.

If it had a sudden overnight increase in oil consumption it sounds like something went wrong with the multiair system. The air system uses engine oil to operate and looks like it is a failure point. The oil usage they are trying to pass off as normal with this engine is more likely a design/assembly flaw with the piston/rings/cylinders. I would talk to the dealer and see what they have to say about the air system.

Thats the next class action law suit....

BTW, I am in contact with the lawyers on this class action. I dont know if anything will ever actually come of it. But maybe this "recall" will at least slow down the consumption. I really like this little car except for that. And if I keep feeding it oil, it should still go 200k miles with proper care.

They deny everything. In this case, all of the dealers Ive talked with have lived up to the name liars when questioned about the tigershark. Its really offensive.

Chrysler had a V8 back in 60's or 70's that would always throw out the first quart of oil and then stop. I can not remember if it was the 440 or one of their others. If you left it a quart low it would stay there. Add the quart back in and shortly it was gone again.

Reminds me of the first time my 6.7 Powerstroke blew up. The dealer was telling me “this is the only one we’ve had fail!” And when I walked through the service bay there were a half dozen 6.7 long blocks sitting on the floor with ventilated blocks. No problem here, nothing to see.....keep it moving people!

My brand new 1994 5.2 did exactly that.

Never heard of that one. I owned/worked on and built quite a few 318 through 440's and never saw that.

The thing I got about the "fix" says it is rare. From what I read, most of them (at least the dodges) do it.

Got a notice of "customer satisfaction sw update" for the pcm the other day that is supposed to fix the oil consumption problem in the 2.4 tigershark engines that are in darts and jeeps. Got it done on tuesday. We will see what happens. They say the problem occurs when coasting in city driving and short trips. Something about creating a vacuum (or stopping a vacuum ) condition in the cylinders by reprogramming the valves. Ive only driven a few miles since so I dont know if it really fixed the oil issue. But the trans does feel much tighter and the engine feels more responsive and maybe a little more power. We shall see.

Yes, now i remember it.
They got rid of zero-fueling during coasting or downhill. That was it, engine braking goes bad with the update.
Not a big deal in flat land but crucial in the mountains.

So you are saying I will no longer feel the car downshift when rolling down hill ? The car does feel more responsive and seems to be in any gear I want it to be when rolling slowly down hill, but I dont feel like the torque converter hits as it downshifts. But in this little car, not a big deal. Even in the mountains. So if that fixes the oil consumption, I will be ecstatic. Thanks for the feedback

 

[Ozymandias]

Please keep us updated on this topic, I'd like to hear first hand how it is with the update.

My HEMI does the same (fueling on decelaration) and it drives me nuts to say at least.
Even in Low Range it goes down the hill like an avalanche. Almost no engine braking.

 

[Tractorat]

Remember this is an oil consumption problem and they have told me the fix involves controlling when oil is being squirted (or not squirted) into the cylinders while coasting. This is way above my 1960's knowledge of engines and how they work.

Got the "fix" the other day from dodge. PCM sw update. Had the oil changed yesterday. So now I will see how it works. Ive been following a dodge dart forum and it sounds like the update does the trick.

 

[Tractorat]

Just over 1000 miles after oil change right after I got the "fix" for the oil consumption. No noticeable oil consumption. Keeping my fingers cross.
