V Power in a 1.8T
« on: 14 January 2010, 15:30 »
I have never bothered what petrol or diesel I have put into any of my cars over the last 20 odd years, its always been a case of pulling up at the nearest petrol station and filling it up with whatever.......I have seen the adverts saying this petrol will do this and this petrol will do that but always thought it was just marketing bullsh!t. After reading through various threads on here I decided to let the tank run down and give Shell V Power a go, just to see for myself.
I have a 2001 {y reg} 1.8T AUM, re-mapped to 220 something bhp {according to the chap I got it off}, from the first test drive, driving it home and running about in it for the last month or so I have not been happy with 2nd and 3rd gear when accelerating.......just seems like there's nothing there until you hit 2500 to 3000 revs, its hard to explain but it just didn't feel right....
So this morning I filled it up was Shell V Power, it feels like the engine fairies have been and put me a new engine in.........Throttle response is definitely smoother, the revs are dropping down quicker when changing gear {before they seemed to hang around the 3000+ rev mark for a split second before dropping}, when you put you foot down the response is now instant and puts a daft grin on your face and i`m pretty sure its quieter, when I say quieter it seems to tick over a lot smoother ........I for one will be using Shell V power from now on and I didn't think that I would notice any difference.........

thats because higher octane fuel allows advance timing and is best-est beer budies with the knock sensor

also you say nothing seems to happen until 2500-3000 rpm, and it will feel like that as thats when you turbo starts kicking in.

also most cars are mapped to run on super unleaded (97ron or higher)

and no power before 2.5k welcome to turbo lag. (or as honda owners know it - the rubbish 3/4s of the rev range  :laugh:)

No, like I said its hard to explain.....I know when the turbo kicks in.......It just felt crap, it wasn't smooth, sort of hesitant between 1500 & 2500 revs, it felt like it stopped for a split second.......Now its feels nice and smooth with no hesitation......

You should uprate that crap 3bar FBR to a 4 or 5 one, the smoothness then is a huge hope, feels like the spool is quicker as well as responsive, specially when you can pick them uup for £25+

Mine didn't like owt but 95 RON (AGU 1.8t), tried vpower, tesco 99 etc.. engine was louder/vibrated more, MPG down, performance about the same.

Turns out it has a 95 ron map on (APR map) and it does indeed run sweeter with 95ron cheapofuel :D

Try giving your throttle body a good clean mate, this will probably help.

And check for boost leaks and a split diverter valve. Common issues with 1.8T
