just a quick one can you really tell the differance between shell v power and normal unleaded ,and does it improve performance,and mpg
-
Rather than do this topic, again, might be worth doing a search :smiley:
-
Yes, for sure....if you are tuned :smiley:
-
...........& it's getting fcuking expensive :cry:.
-
Tesco 99 :grin:
-
Can't say that it improves MPG, but it feels like you have an extra 1000rpm. But at £1.26 per litre I am on the normal shell unleaded for the moment with no real ill effects.

Me too, can't say I've noticed any difference to mpg but there is something missing from the top end. Since I spend most of the time at the lower end of the rev range I'll live with it and save the goodstuff for when I know I'm going to have some fun ...

Mk5 Golf gti will run on 95/99/102 ron but benefits from 98 ron or higher as recommended on the sticker on the inside of the fuel filler cap. Anything below 98 ron will basically lead to less mpg and less power. How much? I don't know.

^^
As expected I have noticed a difference in power delivery at the top end, maybe not quite as eager as she used to be on 98.
MPG wise I have honestly not noticed any difference at all, if anything a slight improvement but this might have more to do with the weather than anything else as its gotten a lot warmer in the last couple of days.
I think the MPG benefit will depend on the type of journey you do. High octane is said to be better as it allows the engine to stay in lean mode for longer, but the engine will only go into lean mode if its at a steady speed and increase in power is not being demanded - i.e. cruising.
My commute is mostly town traffic and a little blast on a dual carriageway; so I doubt it gets the chance to go into lean mode anyway which is probably why my MPG hasn't really changed. Others doing motorway journeys may not agree ...

MPG will improve the colder the outside air is as the air is more dense, thus more air will be be able to be drawn in with every stroke. This is why we have intercoolers. Otherwise it would be interheaters that would be required. :smiley:
-
Ah but a colder engine needs more fuel injected / takes longer to get it up to temp. It will run rich until up to temp... MPG always gets worse going into the winter and better coming out. :wink:

Fail. As ub7rm says, to maintain the correct Air/Fuel ratio, more air means more fuel needed.

What fuel do r32 owners use? i bought one last week and have filled up with v power but the fuel cap recomends 95 ron? I wont bother with the v power in future
if the normal stuff is ok.
clint
-
I guess if it says 95 on the fuel cap then stick with that, but avoid supermarket fuels..?
Ha Ha having said that I have filled my Ed30 with Tesco 99 Ron tonight instead of the V Power I have been using, as various people have mentioned it on the forum as the "other" choice for GTI's. :wink:
Must admit I assumed the R32 would be the same as the GTI though.. :undecided:
-
R23 lump isn't FSI so won't benefit in the same way the GTI engines will from higher octance.

Hello All
I agree with all that has been said so far, but will stick with V Power or Tesco 99.
When looking to buy my Ed30 I looked at Honest John under "Whats Bad" for the Mk5 Golf and this is what he said about fuel...
FSIs are proving to be petrol sensitive. Best run on 99 Ron Shell V-Power Super. Head problems reported at 4 years old if not run on high octane petrol. May also suffer failed lambda probes (two at £200 each) and failed cat converters as a result.
This was enough to pursuade me that I had best cough up a bit more come filling up time, especially as I would like to keep the car for the foreseeable.. :smiley:

shell in Erith, south east london, 123.9

shell in Erith, south east london, 123.9
Erith you say, that’s my neck of the woods. I live in Belvedere and I always fill up with V Power at the Shell garage on the duel carriage way between Erith and Crayford. The one that’s near the big Ford garage.
To be honest I never really look at the price per litre as I know it’s ridiculous, I just hand over my debit card and my Shell Points card and just hope I have money in the bank to pay for it ha ha!
-
yup that's the one I go to too!

But to be fair i used normal shell unleaded at £1.16 per ltr. I agree with steve wer'e getting shafted at the mo
Really? About a year ago the difference between std unleaded and v power for me was about 10ppl, at the moment it's 6ppl with unleaded at £1.20 & v power at £1.26 (I'll be filling up (with v power) at a shell station in guildford with unleaded listed as £1.18 tonight, will see what the v power cost difference is there.
So actually I think we're getting a very good deal atm.
-
From the shell garage in Erith it's always been 7p per litre premium for vpower. the same goes for a shell garage in wales that I use.
-
Where I live near Dartford the robbing F**kers at my local Shell always price V Power at 10ppl more, where as in town it's 7ppl more and starts at 4ppl lower, but just not worth driving into town to save 7ppl. Currently paying £132.9 a litre for V Power.
Although the GTI is long gone, my M3 will not run smoothly on normal unleaded, and it's as fast as filling 1 tankful of normal unleaded before the car gets juddery low down. Have back to back tested tankfuls and they are that sensitive to it. Some M3's act like this, others seem fine without it, although mine is tuned which probably accounts for some of the issues.
-
£132.9 a litre !!!!!!!!!!!!!. £1.32.9 i think mate ?. :grin: Don't worry i've done the same.
