Hi, in the U.K. Shell V Power in 99 octane, whereas B.P. is only 98. I'd use the best available !

 

I am not even sure BP Ultimate is 98. May actually be 97.
But as above. Go for as high as possible.

 

Tesco 99.

Looks like he is from Greece

 

Υes ,I am from Greece

The question is if I can use 98ron fuel for the cp 420 and if it can damage the engine.

 

You could always add an octane booster to the best RON you can obtain.

Can you not contact Collins Performance direct and discuss what your engine is, and needs ?

:facepalm:

 

@Emilio

As above, seeing as you're outside of the UK and your fuel quality "may" be different to ours, why not ask Collins directly?

They are one of our club sponsors and have a good reputation for customer support.

Emigrate to Germany they sell 107 octane in the BP petrol stations.

 

It's definitely BP100 in Greece so I'd go with that. But 420s run fine enough on 98/99 fuel. OP, our BP fuel in uk is 95 or 97 (there used to be a 102 on offer in some place but it was V E R Y expensive).

They sell some expensive one which is around 105RON I think at BP near Silverstone.

 

Greener petrol at UK pumps to target emissions https://www.bbc.co.uk/news/uk-51731757

There is a company able to make fuel from carbon that the capture from the air, as petrol it has a higher octane rating, burns more efficiently and cleaner, they can also make it into a diesel replacement fuel and also aircraft fuel.

These guys right?

That's them, I keep seeing videos posted on facebook. They reckon cost at the pump would be no more expensive and they would need less of their plants around the world than there are power stations.

It's interesting - the article is a few years ago where the cost of a barrel was more than the regular oil but I guess scalability is the key to driving that down

 

BP actually sold Ultimate 102 in the UK for a short period of time. It was ****** expensive (£2.40/litre around 2010) and was sold in a few locations only.

A mate of mine got a tank full for a Vmax event.

The videos I keep seeing on facebook give the impression of being more recent or even upto date.
As to whether it would gain interest remains to be seen.

Sites close to Circuits had it iirc?

 

As a matter of interest would the ECU adapt if you filled up with 102RON or higher after using say 99RON or would it need to be live mapped to make the best use of a higher octane fuel? Will E10 fuel increase octane rating? I checked and would be ok for our cars.

 

Remapping will always get more from a higher octane fuel, but the engine should still run better regardless.

Alot of race circuits sell their own race fuel, likely to be higher than 102 RON though. You can always buy a small drum of race fuel from Demon Tweaks.

 

It seems to be all through Europe France, Belgium, Germany to name 3 all have V-Power@100 and BP Ultimate@102

E10 is going to be available as 95 octane fuel - E5 (which we have now) will remain as the high octane fuel 97 and beyond

the ECU has mapping that caters for differing octane ratings, normally quite a wide range as fuels in 3rd world and eastern bloc countries is of a lower octane rating.

as for higher octane fuels, one needs to run 3-5 tankful through before the ECU will have learnt enough to be of any power difference.

as for ethanol in fuel, it's well known that adding ethanol actually reduces performance, this is due to the fact that ethanol has a lower power ratio than petrol, whilst not a lot given the 5-10% additive aspect, it certainly won't make the RS perform better, if anything, slightly worse I would expect.

The only reason Ethanol is being added is it's the oil industry's way of contributing to the CO2 reduction targets set by global and local politicians to meet global warming targets.

there is a really well written article on this forum written by telegraphroad that gives much more info.

I don't see the ECU in a car being any different to the ECU's we are using on the Dynos at Dunton and all we do is change fuel at the cluster at the back of the cell, drain off 4-5 litres at a tap in the cell to clear the fuel lines of the previous fuel upto that point, then run the engine for about 1/2 an hour at 3000rpm and half open throttle to clear the rest of the lines upto the engine, after that, it's good to go, and the ECU is reacting to the new fuel.
