v6tas Posted September 12, 2006 Report Share Posted September 12, 2006 As posted earlier my weekend RR gave me poor figures. I was down between 10-15 bhp from stock (224bhp). AMD suggested the MAF might need changing as there were no ECU error codes showing up. Spoke to the stealers today and they are taking a look tomorrow but are insistant that this kind of drop in power is totaly down to the fact i dont run the car on Optimax? I find this claim to be way off the mark. I except using normal 95ron will not get the best out of my car but to lose that much power? I would think a couple of horses might be lost but not this many? Can anyone on here veriry this or are they talking out of their rear end as i suspect Link to comment Share on other sites More sharing options...
pomme Posted September 12, 2006 Report Share Posted September 12, 2006 They could be right, as mine does seem very sluggish when i cant fill up with optimax and have to use the 95ron stuff. But i bet they dont even know how to test the MAF properly as mine certainly didnt. Have a search on here on how to do it properly and take that to the dealers when you take the car in. hth andrew Link to comment Share on other sites More sharing options...

[/ QUOTE ] This is more than possible, though 5-10hp may be more realistic figures. Did you mention to AMD that you were running 95ron? Can't understand why you would buy a performance mota and run it on 95ron if it's performance your after (yes I know some folk buy a car for the pose factor). VPower/Optimax works out @ around £50 per year extra not taking into account the increased mpg benefits! You'd be daft not to Link to comment Share on other sites More sharing options...
dogbucket Posted September 12, 2006 Report Share Posted September 12, 2006 IMO the knock sensor can still be too sensitive sometimes even with 6463, so maybe on a RR on 95 ron it pulled the timing back and effected the power? Link to comment Share on other sites More sharing options...
vindaloo Posted September 12, 2006 Report Share Posted September 12, 2006 If you don't feel like paying the extra for Optimax/Vpower give Tesco Super Unleaded 99RON a go, it's only approx 93.9p in most places (up North anyway) & I find the .:R if anything runs better on it Link to comment Share on other sites More sharing options...
R32North Posted September 12, 2006 Report Share Posted September 12, 2006 I'd agree, if the car is designed to run on 98RON and you run it on 95RON, I think that you should expect poorer performance and if its too low for your liking then pop some 98RON in and check the RR again. Only then, if the figures are way low could you truly say that there is something wrong. Link to comment Share on other sites More sharing options...

Dan32 Posted September 12, 2006 Report Share Posted September 12, 2006 Sure I read somewhere that new 99ron V Power boosted power in a test car by 4bhp. Still, if the manufacturer recomends 98ron minimum, I would only use 95ron in an emergency. Would think that running 95 for prolonged period could give bad power readings.

scillyisles Posted September 12, 2006 Report Share Posted September 12, 2006 Funnily enough I've run my Mk V R32 on Optimax (now V Power) since new and obviously the car runs fine. However I did try a tankful of Tesco 99RON over the weekend and noticed a difference. There seems to be more top end "go" and I noticed that the exhaust tips seemed cleaner i.e. less soot than when using VPower Link to comment Share on other sites More sharing options...

Roughnec Posted September 12, 2006 Report Share Posted September 12, 2006 I dont care what you say Optimax has been upgraded to v-power, which means higher octane at the same'ish price. Bp Ultimate if ur rich Super unleaded if ur not Link to comment Share on other sites More sharing options...

Ok so thats a damning condemnation of my fuel choice then !. Not complaining, i only ask such questions to get what i consider to be constructive and usually top quality advice from you all so i will now give the 98 stuff a run and see what all the fuss is about. The reason for my 95 choice is only financial as i hate being ripped off for fuel at the best of times but i take all your advice on board and will be 98 roning it from now on Link to comment Share on other sites More sharing options...
skifly Posted September 13, 2006 Report Share Posted September 13, 2006 i put some stuff in from a total the other day - was the premium and the car drove like sh!t. It kept stalling and felt lumpy at idle and really unresponsive... needless to say it got a tasty load of optimax (or whatever it is now) and it was back to normal again? I felt guilty for being mean to it with cr@ppy total fuel from a quiet petrol station. Guess it had been sat in tanks for months! Link to comment Share on other sites More sharing options...

pomme Posted September 13, 2006 Report Share Posted September 13, 2006 tspar i would if i was you try and use shell stuff as i have heard bad things about the tescos 99 stuff. Also that the 3.2 litre doesnt like the bp stuff, as mine certainly didnt and my friends audi tt didnt, as well as others i have heard about. ps i am in no way connected to shell, and do not benefit in anyway from you buying at shell, just trying to give advice.

I had convinced myself to go for V-power but now i dont know. 8.1bhp just for using the Tesco stuff sounds like the way to go, and its less expensive than optimax (V-power) Link to comment Share on other sites More sharing options...
khutula Posted September 13, 2006 Report Share Posted September 13, 2006 Is the 99 RON stuff only available at certain Tesco's? I went there today to fill up and the Super Unleaded was 97 RON! Is there another fuel? Link to comment Share on other sites More sharing options...
SamD Posted September 13, 2006 Report Share Posted September 13, 2006 Yup it is only avaliable at a relatively small number of tesco stations I believe. Link to comment Share on other sites More sharing options...
