MPG from a EXEO ST TSi 2.0 (208BHP)

Hello everyone,

I've used the search function, and have seen plenty of threads about diesel fuel economy but not much about petrol models. I've had my EXEO ST TSi 2.0 (the 208 BHP Version) for about 14 months now, and it's pretty thirsty on fuel, even on long smooth runs on motorways, though my commute is only 7 miles on country roads - so that doesn't help the average look good.

Clearly one doesn't buy a performance petrol car and expect it to do 60 to the gallon, and I know manufacturer's figures are only achievable with perfect conditions.. (what a con that is!!)

I measure 23mpg from the onboard computer, but also use Fuelio app and that gets 28.5mpg since last November... perhaps this is the going rate?? I'm hoping other TSi 2.0 drivers might share with me what mpg you return and on what type of journey

I thought I ask on the forum if there are any recognised common problems with this type of engine, leaking injectors or dodgy sensors or similar, that cause over fueling. There is a black residue on the exhausts, which you might expect if it were Diesel. I don't know if the car has been chipped/software tuned, it wasn't sold as such.

I see the likes of Revo and Bluefin do software tuning, I wonder if they do maps for economy or just all-out power at max revs? (Great for pub points, not much more). I know the default maps are there to get cars through type testing and emissions tests, and are very often not as "optimal" as they can be.

Hi Folks,

Thanks for your input to this thread, it's taken me a while to get back as I've been busy at work and then laid up in bed with a fever, rubbish!!

I'm tempted to get an "economy" map done, knowing/hoping it doesn't actually knock the performance much. I suspect the factory map has been tuned to run a little rich in places to help the emissions figures to pass the type test.. Subsequently it uses more gas but pumps out less CO2 so it falls into a lower tax bracket. Case in point is that my previous Audi A3 1.6 Petrol was £230 per year (176-185 g/km), but this is £185 (151-165 g/km). This car has way more power, is way heavier but cost less to tax.... RIIIIIIGHT!

Over to the point of why get this petrol when I could have picked a diesel.. well, I recon the government are going to backlash on Diesels and the tax regime will change to include particulate emissions. Plus I only have a short commute and a heavy diesel engine wont get up to temperature most of the time, and emissions gear DPF and EGR and the like have a habit of going wrong under these conditions.

The Honest Johns site pointed out looks to have quite a range and I fall quite near the bottom, which may be down to my driving style or the type of roads of commute on. I've put 98RON in but it didn't give me any measurable improvement.

What type/engine code is in my 2.0 TSi? I was talking to a fella at work about the amount of oil I keep having to top up, he remarked he thought the engine was likely the same as the one in a Golf GTi he used to own - and that also drank oil.

A question for those who've had their car software tuned...

Did you get what you hoped you would?
Where did you get it done?
Was it a generic map or done on a rolling road?

Do you have any suggestions who fits in the "well known" tuning company frame? I don't buy the mags to see the big glossy adverts or the smaller ones in the back pages - all I see is well written websites and hand picked testimonials but not a huge amount of substance :-S Personal recommendations can mean a lot.

Thanks for adding this danjwilko.

it looks like Corten Millers don;t do the Rveo gear any more, and do focus on Diesels and DPF removal stuff. I've put a post in the Revo section.

I can confrim after 18 months of 9 miles commutes on country roads that the Fuelio App (Great!!) reports average fuel consumption of 28 mpg... which is considerably better than the on board computer bothers to report back! (So that's nice). I did get in touch with Revo ref tuning for economy.... not even a "dear John"!
