Excessive fuel consumption

[simond64]

The dealer sent a driver to take my car 160 miles for work that was missed pre delivery, this is a new 2.0 TS, it had 400 miles on it, consumption was ok but this journey he used 30l if fuel to do 160 miles, that’s 25mpg, it does 55-60 for me. Any one know how you would drive to make it do that? MyT didn’t record the journey and oddly the Dashcam power lead was unplugged by someone. 
Car was checked by dealer for faults and leaks, nothing wrong and it gave normal mileage when returned by another driver and for me. It’s a mystery

The driver had a heavy right foot

This is exactly the reason why I choose to go and pick up my new Corolla 2.0 TS almost 200 miles from where I live , and not having delivered to me by who knows what sort of driver and driving style . Following also the advice of not abusing acceleration and breaking for the first 500 - 600 miles ,  plus limiting constant motorway driving in one go  🤷‍♂️

To make it do 25mpg I’d guess you would need to drive it very harshly, he switched PDA off too. It is in its running in period so a bad time to abuse it, oh and he also managed 3 paint chips in the bonnet

In contrast the first 110 miles I have done (14 miles on clock at pick up) the fuel average reads 65.5 mpg. That is amazing but I will get a better idea how it drinks the juice when I do a tank to tank calculation. The weather is very warm at the moment and that's bumping up the mpg a bit. Also very light on the loud pedal as running in nice and steady at the moment. The potential is there though it would appear, for some very good mpg with this new 2.0 hybrid system. Mixed drives on town centre and open 60 mph roads so far.

Did they send a driver from Toyota dealer or Toyota gazoo racing team? 🫢😂
Perhaps some miscalculation has happened, I doubt it it’s possible to go any lower than 40sh on these cars, especially on a longer journeys. 
Did you fill up 30ltr of petrol after they returned the car and did the calculations? 

[fred88]

What sort of work was done? Is it possible engine was running for a while in the workshop? (Though possibly the maths doesn't stack up for that theory.) Suspicious that the dash cam was disconnected though.

Gazoo I think!

 No miscalculation, I handed it over knowing how much fuel and that was on app and dashboard plus I knew mileage since full, then I saw app reading and asked salesman to read dashboard and I know how far it went, car was inspected for faults and leaks when I reported it, somehow 15 litres overused or missing

 can the MyT app recording be turned off? Odd it didn’t record anytime they had it but recorded anytime I had it

Is it possible that someone siphoned out fuel??

He would need to be quick and have somewhere to do it, is that even possible, is there a physical barrier to stop that in the pipe?

Someone in the trade always know how to get around any difficulty.

To be honest, if prefer that explanation more than trashing it

[TonyHSD]

Imo the only way to find out how much petrol was used is if the tank was full and mileage noted then after car been returned back to the same garage and refill the tank at same pump full and do the maths. Any other way leave a gap for error. Even a gazoo driver won’t be able to do 25mpg in this car honestly, no  empty roads to keep it trashed all the way. These are only possible speeds in England early mornings between 02:00 and 04:00  all other times motorways are packed.

I am certain 15 litres is unaccounted for

There must be a miss calculation somewhere. I doubt it was driven that fast over that distance. Speed camera's everywhere would pick up such driving anyway these days. 25 mpg is just not possible so I would think it's not been thrashed to be honest.

I think in future I’ll turn down dealer drivers and do it myself

[Steven83]

The car may have been left running while stationary for a few hours while they tested for leaks. Of course the fuel would burn but no miles added hence the mpg would continue to drop.

Could a Toyota dealer more local not have carried out the work or did this have to go back to a specific dealer who supplied the car. Does the car have to go back to this place if any other issues are found in the future.

It had to go back to the supplying dealer, it wasn’t warranty work. Future service will be a local dealer

[Roy124]

Disconnecting the Dashcam is SOP, GDPR and all that.  First service 3 years ago the dash cam was running and they even sent a video post service of the car underside. 

Later servicing the Dash cam has been disconnected and now they have a notice to that effect. 

As for their driving. I have around 65 going the 8 miles to town.  They can get 45.

The method I've seen used on a few cars is to undo a fuel line in the engine bay, stick the end of the pipe into a jerry can, then click on the ignition to make the lift pump in the tank pump fuel through. Often easier and quicker than syphoning by hand direct from the tank.

I'm not suggesting that is necessarily what happened here though.

This would give about a tea cup of fuel as ign on would just prime the system. You would have to bridge out the fuel relay to continuously  run the pump. All far fetched.

Depends on the car, some will run the pump continuously with the ignition on. Probably less common than it used to be I admit.

I was a dealership driver for about a six months period, driving new cars from the compound to the dealership 170 miles. I always drove the cars on the upper edge of the speed limits, but traffic and the possibility of getting points on my driving license prevented me from exceeding the limits by any more than 10% over. As Tony says it’s impossible to drive so hard as to get only 25+mpg in a Toyota. Someone, somehow  had to siphon some fuel from the car.

[2badmice]

Not a chance fuel was siphoned and slim chance the speed was exceeded, as said by Bernard above, the driver would not risk his job. 

I've worked in the motor industry since 2017 and I will tell you, that you had no idea how much fuel you had or the mileage when you let them carry out this work.   

It's staggering how many customers think everyone is out to rip them off.  There are still genuine and honest people around.  Unless you have strict proof before you handed it over to them, then you cannot prove it either way.
