99.6 RON PETROL

[Reidy10_0]

While at the TT i had a nice wee suprise to find that Shell were selling 99.6 Ron petrol.
I am guessing that they imported it for the racers and decided to sell it throught the petrol stations.
Well done Shell!
Does anyone know if you can you get it in the UK?

Which station was that?

The station in Douglas next to Mc Donalds (used to be Esso) had V -ower, but the day I went there, couldn't get to the V-Power pump so had to make do with 95.

Shell V-Power is 99 Octane which is widely available on the mainland.

I filled up at the Shell station next to McD's at quarter bridge.
They made a big deal about it on Manx radio.
They called it something different from V power.
But hey they did rename Ramsey to Yamsey.

Do bikes really need super unleaded?

I've been using normal 95 in my CBR600rr should I start using 98/99? or is it only the 1000 bikes that require it?

I get more miles from a tank of 97+ over 95, but only when ragging it (which is on the IOM or in Europe)

The general consensus is that you don't need it unless your engine was built for it. You get more benefits if you remap your ECU but then it wont run well on 95.

I always thought a any car/bike using carbs won't make much difference but injection then that ay be different

[black-k1]

I think it’s more than just fuel injection as a requirement. The engine will have to be re-mapped to make use of it. As has been said, then if this is done via a ‘static re-map’ then use of any other fuel may cause some issues. Some modern bike engine management systems (like modern cars) can dynamically re-map the engine according to current conditions and it is these engines that will get an improvement from higher octane fuel.

the ONLY bikes I know of that need anything higher than 95RON are some BMW's...not required on any other modern standard bike that i know of.

Ride magazine tested these higher octane fuels on a dyno, back to back with "normal" fuel, no gains or advantages where found.

Again, when I was at RAF woodbridge last year, all of the (non turbo'd)but modded bikes where running flyers on normal pump fuel.

Let they car boys pay for the nose for this if they want, we dont need it.

Some bikes with carbs actually run (a lot) worse on the high octane stuff, not sure why though.
I have heard it said that the density is higher which would put the calibration of a carbs out, but the specs I can find on the internet show little difference in density betweeen 95 and 98.

Maybe the stuff burns at a different rate? Anyone got any facts that they can share on this?

I also have a CBR 600 and i thought it did feel a bit more perky but not a great deal of difference that a normal joe bloggs rider will notice.
A racer may notice the advantage.
