shell's v power petrol

[scoobydevil]

did a search and can't find this as a topic so started a new one sorry if it has been covered.

just wondered who has tried it and what results you had had.

i have tried it in my mx6 which is 2.6 v6 iand have found my fuel economy has fallen greatly however the perfomance is superb.

going back to the fuel economy under hard driving you can watch the fuel gauge drop much more then with normal unleaded.

as a foot note i am having the car serviced at ABP and will report if it makes any differance.

Do a search for Optimax, BP Ultimate or Tesco 99 and expect

similar results.

Not much point in filling your Westy with it unless its been specifically mapped for it or has a knock sensor. If you have a zetec, these don't have knock sensors so good as throwing  money down the drain.

But, my remapped Leon Cupra, which I can adjust the timing  via a gadget to suit the fuel I put in it, really loves the stuff!

shame we get weak v-power here and not the proper stuff the rest of europe get ..........

[scruffythefirst]

I only put v-power, ultimate or tesco 99 in the dax.  bl**** cossie engines, costs a fortune

What about the bike engined cars then?

I run my Megablade on Optimax (well used to )

Had mixed results running a tweaked V8 in my Westie on Shells V-power.

Filled up at a small village garage and paid £1.06 per litre and the car did seem to go like hell, it also ran much smoother through towns.

I have tried it at a number of motorway services with only slight improvements so not sure if all garages are selling the same goods.

I travel about 10,000 miles in my company car through Europe every year and notice that their fuels (especially in Germany) make a big improvement in performance and economy for both Diesel and petrol engines. I’m sure we are using poorer quality fuels in this country.

We also have a V8 Discovery running on Duel fuel (Petrol and Autogas) this runs much better on gas for both performance and fuel economy than the Shell V-power. Autogas is about 102 octane and less than half the price of V power.

We run it in our Blade and it seems to like it, does the engine have to be mapped to run on it  

[ljsanders]

If your car has a knock sensor to retard/adjust the timing to reduce pinking, then it will benefit more by putting higher rated RON fuel in it. If it doesn't and your car hasn't been mapped to use the higher rated RON, about the only benefit you will have is that the additional cleaning additives will help.

In my 1800 Speedsport, I notice virtually no difference whatsoever over regular 95 RON.

However, if I find myself  out of fuel and at a Tesco's, I won't put the 95 RON in it because thats the crappest 95 RON fuel on the market (in terms of cleaning additives for your engine), so I put in the decent 99 RON stuff.

I'd be interested in knowing the non-performance benefits to using a "Premium" fuel.

Is it worth doing every few tanks worth? Or do you need to run it for a while for it to make any difference?

Be carefull when reffering to knock sensors, they only work up to about 3K then background noise makes them redundant so in road cars they are only used for slow speed problems you know pulling away with a caravan in 4th gear dont expect them to protect your motor screaming at 7K if the timing is out

Optimax and BP ultimate both improve economy and drivebility on my 350Z but then the book says thats whats supposed to be in it so I'm only cheating by filling up with regular stuff.

All V Power in this country is 'brewed' at the Shell Stanlow refinery, so should be all the same.  I have noticed that the fumes that come off Optimax / V Power are much stronger than normal unleaded, so I don't suppose it stays 'fresh' for very long.

I have to use SuperUnleaded in my tin-top ('new' shape Golf 1.6FSI) .  V Power seems better than Optimax was (98RON vs 97?) and BP Ultimate is OK, as is the Texaco one.

The fuel economy is worse than my old 1.6 Golf, whatever I use   , but the car seems quicker than the old one .  I think the new emissions gubbins is taking more power from the engine .

I get marginally better fuel economy with SuperUnleaded in the Westy, but not enough to merit the higher cost.  This cooler weather is better for top-end power, though, because my air temperature sensor does not give a reliable reading, so I disabled the temperature correction in the ECU.

It knocked about £5  off of my  0 - 100 time
