V-power

[Merrsh1]

Fifth gear did a dyno test. VPower came out top

But the test is done on a turboed engine so you'd expect a result. An N/A engine wont show a difference.

What makes you say that? Very few racing engines are forced induction now but racing teams use high octane fuels for a reason...

Thats because the engine can take advantage probably of the higher octane fuel. If an NA engine is built for a particular ron (its in the owners manual for our cars) using a higher ron is unlikely to make any difference.

I used to use vpower, ultimate etc and there is no difference whatsoever. I recently did 1200 miles over 5 day using all types of fuel and there was no discernible improvement or decline in performance.

If im wrong then im wrong but id like to see dyno figures as a.lot of this fuel snobbery seems to be based on the advantage it gives forced induction engines.

I think its all placebo and people believe putting high octane fuel is caring for their p &j more... which is their choice obviously.

The car should run on the spec fuel recommended. The M calls for 95 but I run Momentum or vPower Nitro. The Alpina required 97/98 and ran like a dog on 95.

VPower has additives for keeping the engine cleaner although unless you keep the car a long time you may never see the benefits.

As with everything else, your car your choice.

I wonder if Exdos has run Dyno tests...

Without wanting to sound rude.

The S54 engine in the Z4M is designed for super/98 as stated in the owners supplement; 95 is the minimum.

You're not being rude. I'll see your manual and raise you a filler cap label, which will be what most people see...

As I said, she only gets vPower or Momentum anyway.

taking the "power" side away.... do you think their are better cleaning additives in the higher RON fuel than normal 95?

 

[Stuart Truman]

No idea, but they were marketed as such originally.

 

[the cueball]

I've always used the highest RON I can, not so much for power gains... although I do feel the S8 is smoother with the shell nitro stuff (no marked mpg gains) and of course this could be down to having to justify the expense in my head..... but the other side for me was they cleaned the engines better.... don't if they don't... well.....

the A8 TDi I use for long trips also feels better with super diesel, but of course that is a turbo induction....

you cant compare a race engine in this thread. the engine will have been tuned for the specific grade of fuel it runs to get the max out of it whereas our cars are designed to run on any old shite we stick in. from the finest freshly made v power to the dubious octane rated "petrol" we shove in when we almost run out in rural wales.

for what its worth the westy runs awkwardly on v power. it was tuned using 95ron from chavda. i had the option but with a 25l tank i thought it best to stick with 95 esp as i couldnt get from bala to runcorn at full chat without running out . also while we at it 95 ron is the same from any place. check the BS number its the additives that get put in at the distribution depot that are different.

Also the mpg be benefit of Vpower seems to have dwindled since they started using ethanol in the mix.

Does V-Power have ethanol in it? i'm sure I read in one of the classic car mags that it didn't which is why I started using it in my 1985 500SL. I don't do enough miles in the SL to comment on any improvement in the fuel consumption but I used it in my E36 328 & there was no difference at all.

My friend reports a noticeable improvement using V-Power diesel in his E46 330d.

 

[Woots]

Just stick whatever you fancy in her, if you feel it makes a difference that you can justify stick vpower in, if you don't notice it, then stick 95 unleaded in

It's really not that difficult guys

I have no dramas putting 95 shell/esso/texaco/bp petrol in

So that works for me

Hand on heart I think it's all marketing bollocks. Again I'd like to see two engines ran side to side for 30k on a bench, one on vpower and the other on morrisons premium and then took apart and examined. I think there will be no difference.

I think you would be better every 30000 miles running it through a terraclean machine.

Again I'd love to proved wrong as I'm a cynical bastard and a little humility does me good now and then.

you cold be right... but I thought that terraclean stuff had been shown to be snake oil too???

m'eh... who knows what to believe anymore.....

I think ur referring to redex? :wink:

You're worse than me!

Ed off wheeler dealers says it works, he seems like such a nice bloke...

 

[the cueball]

No,I know Redex is rubbish...

seen a few people get the terra clean and they have been less than impressed with it... promised too much???

again, a total subjective thing maybe.... has anyone on here put their car through it?

 

[Anonymous]

Apparently he was impressed enough to buy a machine for his garage business.

The people who weren't impressed were probably expecting too much. It's not like it's going to bolt on 20bhp like their cone filters do :roll:

It depends on how coked up the car was in the first place. These bio fuels aren't helping.

 

[Stuart Truman]

Isn't he an investor in the business? IIRC this has been discussed before?

 

[the cueball]

^ I believe so...

Since the start of this topic Iv been a bit of a geek & looked into the details. From what I can see Wiki says everything all the other sites say. Here's a link for those interested:

http://en.m.wikipedia.org/wiki/Octane_rating

V-power does contain ethanol but Shell are allowed to legally say it doesn't because it's a slightly different hydrocarbon structure (an isotope) to ethanol which had been synthetically created in a lab & patented by Shell. Technically it's about 5% ethanol but it's structure means it combusts more efficiently creating less knocking & pinking in high performance engines. So it's kinder to the engine so probably helps prolong the life of engine but as far as performance related tests, practically you probably wouldn't notice but lab conditions on paper it probably looks impressive.

Just seen a Terraclean advert on TV. And the car they are using, a new Lexus Hybrid!
