And the hits just keep on coming... 2017 GT350 - low/no oil possibly?

[sk47]

That would be correct but the cars also known to normally burn oil. Just keeping it to 10 gives you a nice safety margin before you notice you're getting low. Mentally "Hmm its only at the bottom dot" is more calming than "omg there is no oil on my stick at all"

Hello; I am an oil checker. I check the oil in any machine often. I check in my vehicles often. I like to have the oil above the low mark. My 20 year old car starts to get about a half quart low at around 3500 to 4000 miles. I usually change it well before at 3000 miles. Only let it go longer onetime when I was physically not able.
I do like the ideal an engine can survive when 40% low on oil. I am not comfortable with ever having to deal with that condition. I am some particular about regular care for the mechanical parts of a vehicle. Had a crew done an oil change on one of my vehicles without my knowledge and then sent me on my way 40% low on oil to the point it did not show on the dipstick, I would be furious. Then engine may be OK, but that should not happen.

Except you forget these engines are known to burn oil. So if you have one that burn a lot, get it documented.

I have found instances where people claim to have been 6 qts low on the voodoo while tracking and no apparent damage. Which makes sense to me. There just needs to be enough oil in the pan to keep the pick up covered under running conditions. 4 qts have been fine since the 1930's.

Facts, not emotion.

Riiight, they don't burn 4-6 quarts of oil! Just try and make that argument at the dealer with your blown motor. You would get laughed at.

Equating what was done in the 1930's to a modern Coyote engine is odd. But feel free to run 4 quarts in your engine.

You take everything to the extreme don't you.

I said some have claimed the coyote can run on a track 6 qts low and not have any damage.

I would not knowingly run my coyote with only 4 qts. Just that if I do it probably won't get damaged.

My reference to engines dating back to the 30's is simply to show the pick up won't be uncovered with 4 qts in the sump. They ran 5 qt pans up to what, the 2000's

Now go away, back on ignore.

Not sure if you meant to quote me or not because at no point did I ever say that it was fine or correct, and my post has nothing to do with that.

Just throwing this out there.

If there’s a quart between the high and low marks on the stick AND Ford says anywhere between the marks is OK, shouldn’t we be saying the 5.2 takes 9-10 quarts and not just say 10?

Well, the way Ford explains it in the Owner's Supplement and the Service Manual, the engine's capacity is 10 quarts, and they direct anyone doing an oil change to install 10 quarts. They also indicate that anyone operating one of these vehicles needs to keep the oil level between the holes in the dipstick. They further clarify that an operator can do so by adding a quart when the lower hole becomes exposed and oil-free during a dipstick check of the engine oil level.

So, while the only numerical value that Ford actually publishes is the number "10", a discerning reader could indeed deduce that if they follow the directions provided by Ford, they will be keeping the amount of oil in the engine between 9 and 10 quarts. However, Ford does not provide that information directly, presumably to test the cognitive skills of Ford vehicle owners and operators.

With that explanation, it's clear that @Tank has passed the subtle test posed by Ford with flying colors!

I’d really like to have the guy who was “6” quarts low and running on a track chime in here. I mean running 2 quarts when capacity is 8, who admits to that?
This reminds me of the “pretty sure” TV commercials. When we use words and phrases like shouldn’t or probably won’t, I don’t get all warm and fuzzy thinking I’ll be just fine.

I remembered wrong, he doesn't say on track.

Hello; Back last fall I was about to buy an F-150 with a V8. Ran across a TSB from Ford about excessive oil consumption in the trucks. The fix was in two parts. First was the throttle body plate was programed so it did not close all the way when the gas pedal was lifted and the engine is coasting in gear. My guess was the same as some others that high vacuum was pulling oil past the rings. So with the throttle body plate open a bit air could be sucked in and reduce the vacuum.
The second part of the fix is to replace the dipstick. The new dipstick reads two quarts or more from full to the low mark. There is a video of two guys checking this. It took over two quarts to get their F-150 to the full mark. Not saying this has anything to do with the V8's in Mustangs.

Add me to the list of compulsive dipstick checkers.

My question should in no way condone running this car when the level is below the bottom hole. I’m a firm believer in @Hack hypothesis these engines like to run at a certain level.

Hello; I was in agreement with your post, not being critical. I also do not think it is fine or correct.
I want to have as much oil in an engine as can be run. I know too much can have the crank hitting the oils and mixing air in it which is not good.

I do not race so have no experience with running low on oil to go faster. I do not think I would try that. Weight may be the enemy in racing, but oil is the life blood of an engine.

In real racing (not tracking a passenger car or making a few weekend passes) engine longevity is way down on the list of things they design for. They get torn down, spec'd, and replaced often. They will sacrifice wear and tear for performance as long as it gets them to the end of the race.

This was after they came to my house and put in 4 quarts so I could drive it to the dealership.

So it sounds like the dealership is trying to take care of you. If they have documented the issue, give you an extended warranty, I would just drive and enjoy! I had my oil filter housing changed, new oil pressure sensor put in and had the air conditioning pump pully replaced after it broke on a track day. No questions, no charges. Ford has been good to work with for me.

I switched from motorcraft to Amsoil. I get it by the case and always have a few extra quarts on hand to top off if needed. I track regularly. My oil catch can has a few ounces in it after every session so yes, the engine "uses" oil. Lots of good comments on the thread, I'd add that you always let the engine drop from its start-up idle before to drive, watch the temp and pressure gauges as it warms. I also like to watch my temp monitor screen periodically and get a feel for where it runs during certain uses. Head temp. Oil Temp. inlet air temp. etc. Just helps to set your baselines and see when things start to get sideways! Have fun and good luck.

Do you have a single catch can or one for each side of the engine?

 

[Meateater]

Do you have a single catch can or one for each side of the engine?

Single. Just for the passenger side. When I did my initial research, it seemed as though the driver side bank didn't experience the blow back. It was recommended that I only install the passenger side can. I went with the JLB machined aluminum set up. Been very satisfied.

 

[DaveB]

Yeah they are going to swap the oil tomorrow morning and asked if if like to watch, new filter and all.

So tomorrow at 9am EST I should have some brand new oil 5w50. They are also going to be doing an oil consumption test... it was not consuming oil for sure lol, at least not that much.

Not much else to do but wait, if there are any other tests you think they should run let me know, I'm not the most mechanically inclined but I can do basic maintenance on the car should it need it i.e. brake pads, oil changes etc...

Oil analysis moreso yhan a consumption test
