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

[beetle6986]

Thanks for this.

Just to update you all, a tech/service van came out to my house. We ended up adding 4 quarts of oil to get to between the hash marks on the dip stick. The tech even said if it was consuming that much oil there would be clouds of smoke going everywhere and with no confirmation of large oil spots anywhere it's safe to assume there were only 6 quarts put in and not 10 as the tech confirmed with me on the phone...

So I brought it into the dealership, they notated it, the metallic sound went away (maybe it's not there now but it was there previously). So if anything comes up, it's documented.

Now I did take it for a test drive with a tech, he could hear the wheel bearing ticking, so they ordered replacement wheel bearings for the rears (that was the random ticking sound I heard on initial acceleration and deceleration) I always assumed the wheel bearings hummed...

I think 10 quarts should put you at the full mark on the dip stick. If it took 4 quarts to put it in between the low and full mark that means you probably had around 5.5 quarts. That’s way too low. If the engine was making noises before you topped it off. That leads me the to believe the low oil was having some impact on engine operation.

It wasn't long ago we had mostly 5 qt pans. Lots of racers would only put 4 qts in the engine to help with windage.

The 10 qt pan is for extended oil change and to help cool the engine.

Seriously I'd be more worried if the oil filter was torqued properly.

Well, he said the engine was making noise until they topped it off. That would worry me.

He pulled the stick, found it dry I'd be surprised if he didn't hear every noise these engines make 3 times louder.

6 feet of timing chain, 4 cams, 32 valves fuel injection...... These engines make noises

Did they fire the Tech? I mean c'mon now, only 6qts of oil in a 10qt pan AND the fact that if it was not registering for YOU, then how in the hell would the Tech think that is ok???? Because it surely couldn't have been registering anything for him either.

Holy hell man....

I'd be livid too and requiring a complete sanity check of the engine.... regardless if some on here think it's ok to run a 10Qt system only on 6Qt or not.... Wow.

 

[K4fxd]

I'm not saying it's OK I'm saying the chance of it causing any harm for the short time he drove it is slim and none.

This is from almost 20 years of being a professional mechanic

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...

 

[K4fxd]

If you can have them run a power balance test. Tell them you are really worried about the engine due to it being so low on oil.

That test will tell you what condition your engine is in. If it fails I would fight for a new engine.

Assuming you read this in time--recommend you keep an oil sample for analysis. Blackstone Laboratories is well known, though there are probably others.

The results won't tell you for certain whether you have a long term problem, but they will provide a set of data points that can alert you to a potential issue or, conversely, give you with some peace of mind. They will also confirm whether you have 5/50 in there or something else.

They can do the analysis with as little as 2.5 oz of oil, but I would capture 5-6 to be safe and would insist on doing it myself as the oil drains. You don't have time to get the kit from them (or whoever you use), so recommend just using a clean glass jar to capture the oil and transfer it later.

Good luck!

Another reason I never go in for my free oil changes.

I'm fortunate that I have a very good QuickLane near me. I always bring my own oil and filter, they do a clean job and charge me $20

Good Luck! Thanks for the updates. @Caballus makes a great suggestion

Don’t forgetto have them change the drain plug..

Frankly I think the engine should be replaced. It made unusual noises and to me that means something wasn't getting proper lubrication. Just because it will keep running means nothing at all. And it will probably still last beyond the warranty period, but it's been damaged by running low on oil. Somewhat subtle damage, but it's there. I'm confident in that.

Years ago I owned a 1990 F150 that had a serious oil pan gasket leak. At the time I didn't have time to deal with the leak as soon as I should have and I didn't want to spend the $1,000 the dealership wanted to fix it. My wife was using this vehicle as her daily transportation. I got into the F150 with her and the oil pressure was zero. She hadn't been monitoring the oil level and it was out of oil. I have no idea how long it ran with no oil, but we filled it. It had 150,000 miles on it at the time. We actually ended up spending the money to have the gasket fixed and that vehicle ran another 60,000 miles while I owned it. I used it for towing another vehicle across several states during this time. It still had good power. I ended up selling it because I was ready to own something else - not because it didn't function.

So my point of telling the story is for those that say things like
"an engine will never run without oil". Yes it will. Longer than you think potentially as well. Especially if the engine is marginally low on oil and still getting some slight amount of cooling and lubrication from the oil still in the system.

The OP never said what the oil pressure was doing during this time. I think he wasn't monitoring it. It's possible the pressure was jumping around as the pump alternately sucked the pan dry and then a little oil drained down from the top of the engine again. That's what was happening in my F150. The pressure would be zero and then it would jump up and then back down to zero again.

And to those that say the engine probably is fine - I 100% disagree. Just because an engine will still run means NOTHING. Engines want to run. They can be thrashed to within an inch of their life and they will typically still run. This engine is under warranty and the dealer screwed up. It should be replaced.

Yeah, all due respect to the mechanics on this thread, but if my car has a dry dipstick I am going to be livid. It was 4 quarts low! Not only that, it was unauthorized and they deducted an oil change from his service plan. Big screw ups all around.

Nah, they would be going through that motor with a fine tooth comb to my satisfaction for sure.

I don't know what you would expect them to do. Tear it down for an inspection? I'd be more afraid of then screwing something up looking at it. If it had lost oil pressure there will be a code stored.

I'd have them do a power balance test and when it passes I'd ask for an extended warranty. Maybe some free oil changes.

There is no excuse for 4 qts low, that "tech" should be fired IMO.
