seems pretty good to me. 28mpg @ 100 mph is good

If that indicated speed was a read out off his speedo then he was only doing around a 'true' 90mph.
Without traction power is nothing!

I thought the police and law enforcement can only prosecute you if they have a video/picture that clearly shows your number plate or some other definitive way to identify your vehicle? It's why I blur all number plates in my pictures that I post (both my car and others) so that's identity is that bit harder from a legal point of view.

But as with everything, not advisable to advertise law breaking so clearly. Better to say "was going a fair speed :wink:" than clearly state your speed, despite the difference in speedometer readout and actually true speed (via GPS tracking) it'll still draw attention from the law.

We all like to put our foot down from time to time, just be careful when and where!

Had my Edition 30 2 weeks and it's averaging 30mpg at the moment.   I've come from an R32 which weighed 140Kg more, had a 1.2 litre bigger engine, made the same power and it averaged 26mpg.

I thought the whole point of FSI was it's economy?  :grin:

The TFSI doesn't do full stratified injection like the n/a petrols.

I'm getting 31ish @ 70 on my 32 mile commute, which pops up to around 38 when @ 60 for the same journey, also don't forget the official combined MPG for a standard car in a lab is 39.4mpg so anything above that you're doing well.

The TFSI doesn't do full stratified injection like the n/a petrols.

I didn't realise there were different levels of stratification?   I thought any FSI motor with the HPFP and direct injectors fully stratified the fuel, otherwise what's the point?  May as well rip it out and go back to port injection.  At least the intake valves would be cleaned!

My GTI is completely standard on 17s with Goodyear Eagle F1 Asymmetric 2 tyres, Castrol edge oil and always run on V-Power. I average 32-38 on short urban runs and 40-42 on longer runs. On a blast down the autobahn averaging 100mph and peaking at 125 it averaged 30.7mpg over about 100 miles. Once I did a 20 mile round trip and managed 46mpg average (there was a lot of pensioners out that day).

I think the economy is really good for what it is, not so good on <5 mile trips but when warm I am quite pleased how good it is.

I'm Stage 2 DSG in my Edition 30 so running about 340bhp with full Milltek TBE and i would average about 18mpg at that speed so would only get around 230 miles to a full tank of around £75ish. :sad1:

40 is fine for the 18's, you can run about 45 PSI with load / passengers.  Less drag better economy.

I've found 36-38 is better for comfort though.

I'm sure they'd take 100PSI++ before popping. :evilgrin:

Checked mine and the tyre shop filled them to 34psi. I stand corrected!

Sat on cruise control at 70 I can get around 450 to a tank, or average of something like 41mpg. I've only got stage1 at the moment

Hi All,

According to the Kwik-Fit tyre pressure search, the below table shows what pressure we should inflate our tyres to - do you agree?

Tyre Size    Front (BAR)  Rear (BAR)   Front (PSI)   Rear (PSI)
225/45R17     2.2 BAR       2.0 BAR           31 PSI   29 PSI
225/40R18     2.0 BAR       2.0 BAR           29 PSI   29 PSI

Thanks
