Oil Consumption Concern

[imbadatthis]

So, I burned ~2.5 Qts of oil (Motorcraft) during a ~400 mile highway drive and half day track session. Photos attached are also very concerning as this crap is coming from the exhaust.


I am very concerned; but I am a rookie. Should I be concerned?

I'd be VERY concerned.

Are you sure you’re reading it right? I don’t mean to be snide, but are you sure you aren’t looking at it since last oil change or longer? Reading it cold vs hot?

My car doesn’t burn much oil. Over a full weekend of hpde, with drive to and from track, I lose under a quart, maybe from midway between oil dipstick mark to the low hole. I see a little soot, enough for a dirty white car, but nothing substantial. And my favorite track, farther away from me but slower, I lose even less. 400 miles and two four session days and my dipstick barely moves.

If you’re sure of your data you need a trip to the dealer.

I'd be concerned. Make sure you consistently measure oil level after the engine has been shut down for awhile and on level ground.

For comparison my car goes to and from the track 300 miles plus the full track day with no consumption.

Go take her to the doctor

Peace of mind would be to get it checked.

That sounds like a lot of oil for the amount of miles!. What year is your GT350?

Top it off and start keeping track of it and when/if it is indeed oil consumption, then post here.

Not the end of the world if it is consuming oil. It would probably mean some valve work.

Thanks all.

I am measuring consistently and will monitor it more closely over the next few weeks while starting my documentation on this.

It's a 2017 with 10k miles.

Greatly appreciate the feedback!

How long have you owned the car?

So I had my motor replaced this past week after doing an oil consumption test. The results were 1.5 quarts within 420 miles. Compression/leak down test showed a loss of 40% in cylinders 1, 2 and 25% in cylinder 3. Ring failure. My plugs were coated in carbon. My exhaust tips were coated in soot like yours. Take my advice and go to a dealership you trust and do the oil consumption test. Don't do what I did and spend time trying to diagnose to see if you have an oil consumption problem. The replacement engines are for model year 2019. Myself and 3 others had our original long blocks replaced with 555 GT350R long blocks. Just so you know, 555 is GT350R and 557 is GT350 motors.

I've put 650 miles on the new motor and am very pleased. Also, I am not concerned about not having a numbers matching motor/vehicle. I want to enjoy this car and be as worry free as possible about my experience. I've owned the car for 3.5 month and for the first 5,000 miles I was stressing over the oil consumption. Some here on this forum even saying I was being sensational

So again.....don't spend time and wasting your money on self diagnosis. Take it in to the dealership. They'll change the oil. Mark the level then have you drive it for 500 miles. If test shows consumption, the next step is compression and leak down test. If the motor fails, Ford will authorize a replacement. Mine took 2 days of me testing/driving. 1 day of testing by the tech and getting a replacement authorized. 2 days shipping and 2 days for removal and installation. I was very much okay with the tech taking his time to do the swap. My swap was the 2nd the tech did and he knew Ford's process for mine. IM me if I can do anything to help.

Trade that bitch in before you need a replacement motor and goes in the Carfax and other records.

I feel for those that have engines burning oil, I had one once and it just made my stomach churn worrying about it. I must have one of the best motors, after 1000ks I can wipe my finger inside my exhaust tips and have zero soot on my finger. Get it looked at and fixed soon so you can stop worrying and enjoy your nice car.

Well, you are from down under, so unless you track your car, there is no way in hell you can use oil. I mean doing 40 miles an hour tops in the city and 60 miles on the dot on the freeway in 6th gear, you can barely warm up the engine from Sydney to Melbourne. The plethora of cops, speed cameras and horrible drivers will ensure all of the above.
....and yours is a GT, not a GT350, different cattle of fish; mate

Gee, you get pay a shitload for a GT350 and it automatically comes with horrendous oil consumption, money well spent!
Don't assume all Aussies live in Sydney or Melbourne, I recently drove 1500ks at speeds consistently over 160kph in ambient temps of 45ºC, I can do that where I live AND with not a drop of oil consumption. Tracking a car shouldn't make it drink oil like it's going out of fashion.
By the way, it's "kettle of fish"....mate!

Unless there’s an actual issue, running these cars hard doesn’t cause excessive consumption necessarily.

Riding the crackle, low load high rpm etc that shoots it out the tailpipes. And, since the exhaust sounds so amazing on any solid rev matched downshift and when you lift etc..

But yeah drive it > 6/10 or like a Camry all day no problems
