[Solved] DIC showed poor economy when new, but has gone down since

Hi Scotty, after viewing countless YouTube videos you made, I finally took the plunge and bought a brand new Toyota Camry 2.5l petrol 2023 last week.

On the day of delivery, I noticed that the car's odometer was displaying 8.9km. At the same time, the average fuel consumption was 150L/100km and the total elapsed time was 2h 8mins.

The salesperson told me that this was normal because the workshop had to run some tests on the vehicle before delivery causing the off-the-charts figures. Somehow, I don't believe him.

To me, it doesn't make any sense that the average fuel consumption was so high when the car had only travelled such a short distance.

Did someone rev and abuse the engine while the car was stationary or is this really normal like what the salesperson told me?

Thank you very much for any help and insight into the problem you can provide.

I don't know what those figures mean in real miles per gallon but it's quite possible the car sat idling for a long time while being checked out and prepared. Of course idling time is zero miles per gallon, and lots of idling can bring the average consumption way down especially if not driven much otherwise.

Are you getting normal fuel consumption on the road?

It is hovering around 7 to 8L/100km. 

You should be happy with 7

However, my main concern is if the engine was abused and permanent damage was caused.

you have no evidence for abuse or damage. Don't be concerned.


I wish there is no need for concern. Other than the off the charts figures, there is indeed no other evidences of damage. However, there is also no evidences that it is not damaged.


there's also no evidence that werewolves do not exist


But there is also no evidence that werewolves exist.


Exactly, just like you have no evidence. You're chasing ghosts.


Can you read? It burned 12L of fuel in 8.9km. You need to get out more, even if it is chasing ghosts.


Don't worry I'm not stupid. I read everything you wrote, and we already explained the reason to you. But the guy who's never owned a car in his life thinks he knows better. I suggest that you mind your tone when asking for help.
Good luck.


Ooh... Somebody is angry.

Btw, I paid for this car in full using money I made.

For somebody who always takes out a loan, you sure talk like you know everything.

I simply used the tone you used on you. If you feel unhappy about, then reflect on yourself.

Don't rely on the car calculator. Fill up your gas tank to full and run your car till it's half empty. Note the volume of your tank and use it to calculate your real MPG.

That is normal for all new cars. Factories test each one to see if everything works. Some dealerships reset odometers to zero.


It seems truth does not suit you.


Are you 100% certain dealers have the practice of resetting their cars' odometer. The last time I checked this is considered fraud.


I read it once somewhere. Mainly because some customers don't like to see these 10 km on a brand new car. I personally would not buy a car from such dealer.

Obviously 150 LHK is an absurd number, and it's completely normal for a brand new car that hasn't been driven.

There's no driving history to provide an accurate number

Well you should, because he's 100% correct. When you idle a car you're burning fuel, while not going anywhere. If you were to calculate the instantaneous economy while idling, it would be infinity. So yes, idling skews the economy big time, especially when the car hasn't been anywhere.

 

Just drive your car and be happy. You need to put more miles on the car before the computers starts showing accurate numbers. I'm sure this is all explained in your manual .


Using the odometer reading of 8.9km and 150L/100km as the basis of calculation, this equates to the car consuming nearly 12L of fuel while being driven over only a very distance. I wish to enjoy this new car moment as much as the next guy but would idling a car burns 12L of fuel. Surely alarm bells would be going off in any intellectual person thinking methodically.


You are easily alarmed . A normal person would hit the reset button and then see what happens.


Sure, if only this is another do-nothing achieve-nothing game where you can hit reset and everything returns to normal. But this is the real world, hitting reset will do nothing to restore the damage in the engine. You play too much games.


what damage? you're playing games with yourself.


If the engine was revved at high rpm while stationary for prolonged periods, cylinder scoring is a possible damage.
Maybe you can share what games you play. I will definitely try them out.


There is no evidence the engine revved for prolonged periods. You made that up in your head. Did you put a boroscope in the engine and find cylinder scoring? I think you need to forget about games and focus on reality.

Using the odometer reading of 8.9km and 150L/100km

(...)

and the total elapsed time was 2h 8mins

I thought about it for a bit and I think I found what probably happened.

 

Your economy / trip probably was reset at some point, it does not show the average over those 9 kms.

Since the reset, it probably idled for an hour or so and only driven a bit - it would cause that reading.

 

If the trips are less than the odometer - it's definitely what happened, otherwise it's the most likely option.

Are the trips less than the full odometer reading?

 

Does this Toyota have an "After Reset (...) Time elapsed", how does it compare with total time elapsed. (I am not particularly familiar with new Toyota trip computers)

However, my main concern is if the engine was abused and permanent damage was caused.

Very unlikely.


Thank you for your reply.

I read through your response very carefully and would like to point out that total elapsed time cannot be reset according to my knowledge.

The trip computer do record a second elapsed time of individual trips which resets automatically every times the engine is shut off.

The overall average fuel consumption is like the total elapsed time.

There are also tank average fuel consumption referring to the average fuel consumption of the current refuel. There is also a trip average fuel consumption. In both cases, the numbers will reset automatically. However, the overall fuel consumption will remain.

The figures I cited were from the overall average fuel consumption and total elapsed time. Thus, they should reflect what happened in the first 8.9km.


No, you can very much reset “total fuel economy”


Dan is right. If someone reset the economy computer and then did a bunch of idling, it will show a very high number. I know because I've been through this with my vehicle.


Yep, or if the battery is disconnected (for whatever reason, for example for fire safety in transport) then the millage before the disconnect is not counted within the economy.

I have driven around 1000km since taking delivery. The fuel consumption so far seems normal for a 2.5L petrol Camry. It is hovering around 7 to 8L/100km. 

However, my main concern is if the engine was abused and permanent damage was caused.


Is this your first new car?


Yes, which is why it is turning me OCD.


Somehow I understand you. What damage do you have in mind? Facfory staff probably have some prescribed control patterns they carry out. They probably have a time limit in which they test each car before they move to the next one. I doubt someone would deliberately destroy engines.


I am worried if the car was deliberately revved at high rpms for prolonged periods leading to cylinder scoring.

I had seen rental car companies' staff did this when they were goofing around.
