Hello all,
in EU and probably also in rest of the world we have "bioecowarming" madness transferred to adding some chemical staff to the petrol. Sometimes 5%, sometimes 10%. Sometimes alcohol, sometimes something else. But only a sick head could have thought it up. In the fact, the real results are:
1) Higher fuel consumption. The engine needs for example 1l of petrol to run. If instead it receives 1l of a mixture that realistically contains only 0.9l of petrol + 0,1l of ****, it will realistically consume 1.11l of fuel mixture for the same let's say distance or working hour.
2) Ruined tropical forests and agriculture. This "bio" has caused natural forests to be burned and palm trees to be planted in sub-tropical and tropical countries as part of this ****ed-up ecology. The oil from them is then transported in ships halfway around the world.
3) Damage of the engines. Mistakenly I forget some old petrol**** in the tank of my old motorcycle for a year. It took out the engine, which was theoretically built for it, but this crap clogged the injectors so that the engine is unable to idle revolutions.
The result in summary: higher consumption, cleared forests and destroyed engines. Bioecobluegreen in the socialist-brussels way.

But by buying of the Rocket the seller told me that 100-octane petrol is not good option and I should not use it due to overheating. What do you think about it? Do you have some personal experience? Of course, by really daily use, the mixture of real petrol and some "replacement" could not be problem, even nobody knows from long-time view. But, Rocket is not from the cheapest things and I would like to not risk clogged nozzles or destroyed rubber hoses and gaskets.
Thanks for you opinions and answers!
 
I'm no expert, but i'm not a fool in relative terms. Meaning I read stuff and try to weed out the hype from the truth as best I can.

I currently have a rule of thumb when it comes to fuel choice when running not just my Rocket, but all my petrol powered machinery/cars. I'm based in the UK, so fuel pricing does have some influence in my decision making, to some extent.
When i'm using the bike regularly I use E10 95RON petrol but if i'm not running the fuel tank down regularly, I use E5 97RON petrol, which should help reduce the chance of water contamination in the tank and extend the octane value of the fuel.

Whilst I understand that modern 'high performance' engines run better on higher octane fuels, I think that this logic only really applies to situations where you are trying to get the max BHP out of the engine, and 95% of the time on normal roads, you're not doing that.

Regarding ethanol content in fuels causing premature fuel line and associated component failure (eg, lines/hoses, pumps, filters, plastic tanks etc...) Most modern vehicles have been revised to combat these issues. Not completely but better these days than say 15 year old vehicles for example. At least the Rocket has a steel fuel tank and not a rotomoulded plastic one, so thats one big ticket item not to worry about.

I'm interested to hear what others have discovered on this subject.

Problem is, that in Slovakia we are not able to buy E5 95RON or E0 95RON petrol.
 
The only option I have is what is labelled as 95RON, with 10% ethanol. It used to be 5% until recently.
Ethanol content and octane rating are two different things.
Have not had a drop in fuel economy.
 
Esso or Shell 97/98 octane in Rocket, lawn mower I use an alkaline based fuel that can sit there for years without issue, I did once use 97 with an octane boost and I had flames come out the mower!
 
I have heard stories about % values of ethanol content varying quite a bit at the pump here in the UK.
I was told that some pumps marked as E10 'occasionally' supplying fuel closer to E5, which for us, is a good thing because it's a better product.
Could be fake news, but could be some truth in it.

Regarding octane rating: Personally, I would send an email to Triumph tech department for a definitive answer, but I vaguely remember Richard Albans writing on this forum about the subject and if my memory serves me right, he was saying that if an engine can't take advantage of higher octane fuel, it doesn't necessarily mean that you can't run it on the higher octane stuff as the engine management system will make adjustments to the ignition timing/fuel-air mixture to protect the engine from damage.

That said, 100 octane sounds a bit potent and not something I have ever experienced knowingly.

Martin are you a helicopter mechanic? Work on military base? My son met a guy named Martin over there and well the world is small and I wouldn’t be surprised if it was you. Thanks kevin
