Super or regular?

Why would you want to do that? Just fill her up till she clicks is surely the easiest and most sensible option?

Well you can get another 60-70mile range - and if you have a Tesco 5p a litre off voucher, you might as well max out your discount.  Anyhooooow, I hate filling em up - rather be driving em!

the tesco 5p off vouchers are a total con.  next time you get one, look at the next petrol station near you, i guarantee tesco's will be 3-4p more expensive, so you're only saving 1p.  every little helps - total con job.

Depends where you live, Shell garage 100 yards from Tesco's exactly same price.

Beter standard of living  Not going to bite with that comment..... At least our drinking water hasn't been through about 4 sets of kidneys

Anyway local petrol price at both Shell and Tesco 100.3p

Round my way, Tesco juice does vary quite a bit in price.  If I go into the city (or its outskirts), Tesco and Shell are generally on par, but any Tescos out in the sticks are usually about 5p a litre more!

BUt anyway, even on the odd occasion when Tescos is more expensive than V-Power, I'll normally always go for the Tesco stuff, because it has been repeatedly proven to be more 'stable' than V-Power.  Oh, and SWMBO likes spending my clubcard vouchers, whereas she turns her nose up at the Shell Drivers Club vouchers!

i've used super all but about ten times in my impreza wrx- tbh i've noticed very little difference in it power/ fuel economy, and the filler cap says 98+.

Yes, but what type of 'super'?  Becauase they aint all the same.  Most supers in the UK are actually only 97 RON - so hardly an increase over the standard 95.  But Shell V-Power and Tesco 99 are both 99 RON - which is really quite a difference over 95 RON.

Secondly, because you 'normally' use 95, then your ECU has probably 'adapted' to run with less advance on the timing as its 'default' settings - and when you do occasionally give it a splash of super, the ECU doesn't have long enough to properly adapt, before you end up slinging poverty-spec juice at it again! 

in fact running a tank of 95 after 98/99 seems to be better if anything- but the scoob doesn't have a range computer- just a rather uneven fuel gauge.

That IS a well known phenomenom in that scenario, across most makes of car.  The in-depth answer is a bit 'tecchy'.

i'll probably give the gti a test and if i see a benefit out of super i'll use it, otherwise i'm planning to go back to regular

If yours is a Mk6, then it would seem you may not actually notice any benefit with super.    With a remap though, that is different!   

I use shell v-power or tesco 99, only buy super from bp/esso/ total if i have to and 95 only if i'm out in the sticks with no alternative- so think you got the wrong end of the stick- very little poverty fuel for me!

i was assumed the ecu still thought it was on the good stuff when i put in the normal, but don't understand why it seemed to be better on fuel then?

maybe i'll alternate on the gti

Forgot to fill up so had to use the Shell on the way to work this morning. 1.11.9

Stuck in 15 quid and will be using the Tesco later this evening, its always MUCH cheaper.
