Title: DTUK motorway mpg
Post by: ffrank on 15 January 2015, 23:49
Hey all, question for you dtukers. I'm starting a new job and moving from being home based with occasional travel to commuting 450 motorway miles a week.

I've flirted with getting a dtuk for a long time and I'm thinking of getting one shortly. I know the dtuk can give comparable mpg maybe even improve it in some cases, but what about motorway miles?

At say a 75mph cruise, are we going to be more or less efficient??

I'm going from a 45p a mile job to paying for 20,000 commuting miles out of my own pocket - so it bears thinking about!  :smiley:

It'll be about the same, although the MFD reading will be more optimistic with one one. It might be a smidge better. If your MFD (at stock) is currently reading around 3% optimistic, it'll become about 9% optimistic with the DTUK box on. If you were actually doing 45.0 mpg for a trip, the car would be reporting 46.4 (stock) or 49.0 (DTUK). The car is always using a little more fuel than it thinks it is, and so when you're using a "normal" amount of fuel, the car thinks it is being extremely frugal.

In the Summer I did a round trip from Newcastle to Leeds (105 miles each way), and got an actual 54mpg down and 58mpg on the way back (59 and 63mpg indicated) – maintaining 80mph, except for a 10 mile stretch on the way back through average speed camera zone – explaining the extra 4mpg I got going home.

I had far fewer active/forced regens with the DTUK box than I’m getting now (some of that may be due to winter driving, and the warming up inefficiencies that come with), my Dad now has mine on his DSG GTD and loving it. I gave mine up thinking that in winter on Bridgestones I really didn’t need the extra power (but miss it), and I’ll appreciate the R more (if it ever gets here) coming up 116ps instead of 60ps.

I do a fair few miles that are mostly dual carriageways/motorways. My MPG is always consistently above 45MPG unless I'm absolutely booting it. With the DTUK box on (and taking into account the 9% increase in readings) I think the MPG has improved, inspite of the cold weather threatening to make my MPG worse.

Frank,

is your car manual or DSG?. And were still offering the CRDT+ for £365.95 inc vat and next day delivery  :grin:

Cheers guys - it sounds like as I expected (hoped), can probably expect similar MPG or slightly improved even. Appreciate the info.

Cheers Andrew, it's a manual :)  What do you think about the motorway MPG? Also, how is Trevor these days - any further tweaks since your last update?

Right, decision made - going to add a Trevor but going to be sensible and wait until the start of March.

This will allow me to have the 10,000 service out of the way (it's so close now I may as well wait), and also let me renew my insurance which ends in Feb.

I'm with Admiral multicar currently which will handle the DTUK fine (£15 extra), but I need to make sure they don't try and screw me at renewal and if they do, that I can find another cheap quote who don't mind the box. For example, Swift who I have used previously and are by far the cheapest for me (£225) - don't allow ANY engine modification.

Is that all Admiral charge for the box? That's good to know.

It was indeed! I think that's basically an admin fee, although I was half way through the year so I suppose it might have been closer to 30 quid from the start of the year. Thinking of getting one too mate? (I totally missed that if you already did!)

The only thing with Admiral was they were right dicks about my factory options and actually refused to cover DCC! I did get the feeling if I spoke to another operator on another day it wouldn't have been a problem. A manager was supposed to call but never did and I didn't get round to chasing them (I had already spent 2 hours on the phone at my cost.)

Ugh, you won't believe the agro I had declaring the Sport and Sound pack with Admiral. They're the only company I know that get so retentive over factory fit items and the need to declare so meticulously.

I spoke with a few people and all of them repeatedly failed to grasp the factory fit aspect of the exhaust - they kept insisting it was after market!

Got there in the end but crikey it was tough. I feel your pain  :sad:

Yeah I've got one. I got the new Trevor before they even had time to put the stickers on and then MonkeyHanger got the new one also so we could compare  :smiley:

I've only been using it on my private land  :whistle: but now my insurance is due next week I'd like to use it on the public highway so wasn't looking forward going round all the insurance companies so that is helped cheers.

Maybe Andrew has a list of reasonable insurance companies for this mod?

Argh, so annoying! I had the exact same conversation. If by some miracle they do offer me a good renewal I will no doubt have fun again. I don't even remember what happened with the Sport & Sound, I think I just told them the calipers were painted as I was losing the will to live and he moved back on to the DCC "So, you have modified the suspension sir?"

Ah awesome, I missed/forgot about that. Going well for you? (On your private bit of land!) Any comments with the S&S and Trevor, I presume it sounds the same?

Yeah, any info from Andrew would be handy, but admiral should work well for you - if you have another car to add now or later in the year you can get 10% discount on both cars or something like that, with the multicar.

Yeah the Trevor is going well.
The S&S package sounds the same I think. Although my boy who hasn't long started to drive was commenting on it the other day on how the growl sounds deeper now!!

I'll give Admiral a try. We have 5 cars in the household. 3 kids me and the Mrs and I've just got us all with Direct Line as nobody could beat them on the multi car.
£180 for my GTD, £600 for my 18yr old boy on his own insurance. So it would be a wrench moving them away as I don't think Admiral were that great for younger drivers but you never know.

Cheers

Why are people declaring things that are factory fit? Insurance companies ask what the market value is so when you tell them you shouldn't need to declare any factory fit items. I haven't told my company I have nav pro, winter pack, DCC, camera etc.

Sounds good p3asa. I have wondered if the cold weather has helped the exhaust too, sounds particularly savage on occasion!

I'll have to try direct line too, let us know how you get on with quotes too mate.

Hi mcmaddy, its just admiral. They ask you for any non-standard options. It doesn't matter that they are factory options, they still ask you about them all and then spend an hour trying to figure what the f*** they are! It was the first time I've ever had this, so maybe it's a new policy at admiral - or hopefully a blip in their training! I'll be finding out in about a month...

If it's just admiral then the best thing is to avoid them. They sound like a set of clowns!

I had a discussion with an insurance broker on another forum and he was adamant that any extras had to be declared when insuring your vehicle. Not only on new vehicles but second hand ones.
How crazy is that? Some dealers don't even know what should come standard in a car due to mid year tweaks never mind your average punter.

Post by: mcmaddy on 22 January 2015, 19:21
It's just another thing for insurance companies to fleece you for. How are you supposed to know when buying a 2nd hand car what was standard or an option. Ridiculous situation!
Title: Re: DTUK motorway mpg
Post by: p3asa on 22 January 2015, 19:34
Yeah that was what I was trying to say above, as cars change their spec usually once a year, then you have the run out models that usually get a bit more on them.

I doubt even a dealer would know what was standard on your 2nd hand car at the time so how would the punter know.
