Tesco 99RON and MPG

Using Shell Optimax average fuel consumption was 28mpg which I thought was fairly good. Might try same run next time with Tesco's 99RON and see how the figures compare.

The beauty is that, at 2900 RPM you are travelling at about 75MPH

No speeding ticket AND money in the bank due to a saving on petrol ... everyones a winner!!

I think that depending if you your is UK spec or an import is a major factor on how many revs you do at what speed. I heard that some of the Jap imports are limited to 114mph so rev hight for the speed they are doing where as the UK spec cars rev much lower at comparable speeds.

Thats a bit pretentious of you as:-
a) ScoobyNet probably only consists of 20% of the Subaru Community
and
b) Some actually enjoy my style .... you don't, that makes you very odd

My brake pads and discs are still original at 63500miles .... I am actually getting concerned over this as it appears to be well over the 'normal' - I suspect that changing them will be difficult as they haven't been disturbed in 5 1/2 years.
63500 and original brakes?????????
There good for about 5000 miles and even then there like banana's
What on earth is going on??????? Have you got a middle pedal????
Are you one of those people who starts slowing down half a mile before a roundabout?????

But 64,000miles has just been turned and the brakes are the same as they were when they left the shores of Japan!
I do drive with vision, I slow before junctions and roundabouts ..... if you use your brakes you have wasted energy (wasted energy = wasted money!)

Wasted enery is good, more fun!!
Why don't you buy a Dumb, sorry Smart car??
And how on earth could YOU ever experience brake fade???????? apart from having sticking calipers that is .....but then again, not with your 500 miles from a tank
You are new here .........
I guess you still drive like a wally, just because you think you have to??
Nah, eventually you will learn how to drive properly and then you will grace the top table with me

And surely, if that is all you have to get out of the car, surely another more sensible buy would have been the way to go?
I am lost
I just dont get why you would buy any kind of Impreza to drive like that.Please explain yourself you silly tnuc.

I am the one that gives Subaru Imprezas a GOOD name ............. you, driving like a complete dork, are dragging the good name through the mud of CHAV Alley!! STOP NOW!

I reckon I have dropped to 18-22mpg!!!
Now either the Pikeys are nicking it .... or Tesco 99RON is CRAP for your MPG figures!!
NOT HAPPY!!!!!!

OR should I say: Leadfoot Larry!!!
Pete,
Their is a difference between driving like a prat and driving reasonably quickly where conditions allow.
On MPG, while my car used to be a weekend car, it now gets used all the time. MPG between fun and normal driving never seemed to vary too much and was about ~20, swapped to 95ron (STi Type UK) last week and my MPG has gone up !

But, I get cheesed off with CHAVS telling me I shouldn't own one of the best cars in the world, just because I don't drive like they do (like a complete utter ********!)

I have seen them ........ BIG exhaust, Music blasting, Baseball Cap wearing, CockLink watching GIMPS ............ Derrrrr brains!!

Pete
Well, i don't expect good MPG. but i won't be drivng my car like a chav.
I have learnt my lesson about speed. There is a time and a place.
I worry about MPG in my work car, not my weekend toy.

P.s.. i am not sure if i will get one yet...

CockLinks make a difference??
Lets look at the facts shall we??
1. The Impreza has a Knock Sensor already, why duplicate it?
2. The Subaru Knock Sensor is attached to, and talks directly to, the ECU.
3. The CockLink is FULLY adjustable .... adjust it until you only get a green light, WTF??
It is an utterly pointless piece of crap ....... fully deserving of its COCKLINK title!
If it is set up properly, and remember its adjustable!! By the time you have seen a RED light, your brain has registered it (remember that if you have a CockLink your brain is much slower than normal!). you have adjusted your throttle position, you have a blown up engine!!!
So, at its BEST, it tells you with a RED light that your engine has gone BANG!!
Thats GOOD then!!!!

The Subaru Knock Sensor and ECU do a good enough job!
Don't waste your money ............ unless, of course, your brain doesn't work properly

But then you will buy ANYTHING!!

Can I interest you in a Timewarp device I have invented - lots of pretty lights - will increase your sexual prowess too!! £999 to you!

Knock does not destroy an engine straight away. It is cumulative damage (as far as I remember). The knocklink could be used as a diagnostic tool in certain circumstances, warning of knock occuring and allowing the user to do something about it (anyone know if the factory knock sensor can fail without the ECU knowing ?).
The quote 'remember that if you have a CockLink your brain is much slower than normal!' tends to suggest intollerance, come on your better than that.
As to their effectivness of actually detecting knock, I cannot say.
Anyway, as to why your MPG has gone down, does anyone know if the calorific values of 95,98,99 are the same ?
Seems odd that mine has gone up with 95.

From the title I was hoping there would be some useful debate in here regarding the release of 99RON fuel at Tesco, but it just seems to have turned into a stage for Mr Lewis to entertain himself by playing devil's advocate.
Would anyone care to get this thread back on topic as I, and I'm sure a few others, are genuinely interested in the fuel?
Thanks.

Of course pinking doesn't blow your engine up as the ***** say, well - not straight away anyway ............
The objection I have about the CockLink is that you can actually ADJUST it to get a green light if it is showing red ................. thats like bending the fuel gauge pointer upwards if you don't like it saying that you are empty!! ie. it's completely useless!!
Back to fuel ............ I now have Sainburys in and seem to be running up at 28mpg (which is a truly remarkable turnaround from the TESCO stuff)
I've never seen anything like it ....... Tesco 99 RON makes my mpg halve!!

I will risk it again, just to check - but watching the gauge moving had me thinking that I really was losing fuel through a hole or something!
