Shell VPower
Hi All,
Anyone used any of this or know if it would upset a blade engine?

I dont know v power in particilar, but if it is similar to all the other posh fuels on forecourt then your wasting your money.
All they do is have a higher RON rating, which means it will not preignite as easily (KNOCK) which wont be a problem in your blade unless you have
up'd the compression considerabley.
Works on certain bikes that have higher compression ratio, like some of the latest BMW's.

If you remap your engine you might get some small benefit but otherwise you are just burning more £s per mile imo.

I always found the higher ron fuel used to use it twice as quick and to no real gain.
A bottle of octane boost works out cheaper i think.
Wheni felt rich i used to put it on my Fiesta zetec-s. It did 190 miles to tank instead of 300 and i drove it no different.

dunno if its logic or not, but if you put more octane in a liter of petrol then there should be less room for petrol it self??
(the stuff that burns..??)..
sow kind a logic..
Tks

With the older engines such as the Pinto and the Crossflow, when unleaded and LRP came in you had to retard your ignition by 2 to 4 degrees thus
loosing power, higher RON fuel allows you to advance the ignition and regain the lost power.
If you already run unleaded and the engine does not knock then extra RON wont help much.
I do know that some engines with knock sensors can be set up to advance more for the higher RON fuels thus giving you a bit more power.
However the engine should be set up for the fuel used and to get the benefit of the higher RON fuels an increase in compression ratio is needed.

V power makes a noticeable difference on my old pinto, but doesnt seem to make any difference on any of the modern cars I drive.

Nope, don't bother in any stock Japanese BEC (i.e. nothing more than filter and exhaust mods).

" if you put more octane in a liter of petrol then there should be less room for petrol "
that's true of "octane booster", though thay can be (e.g. toluene) fuels in themselves.
I was always under the impression that petrol WAS octane, i.e hydrocarbon CH4 is methane, then C2H6 is ethane, onwards & upward though pentane,
hexane until you get to C8H18 which is octane.
I would not be surprised if I were utterly wrong about this......
PS I was largely right
