I swear by it for the car (designed to run on Japanese 100 RON super unleaded) so I tried it in my 97 600 and it made no diff. I reckon it'd work well on an remapped injected bike running more ignition advance, but bike management systems aren't sophisticted enough to take advantage of the higher octane by themselves unlike modern cars.
It benefits older cars etc that were designed for leaded petrol high octane ratings. I use it in my car and get slightly better economy/performance. I used to put super unleaded in my SRAD and it certainly ran better. I always use this or BP ultimate as I have read a lot about the cheaper petrols being crap. It should really make no difference in a new bike. Go to Germany and get 100 octane stuff!
Some cars like it, some don't. My old Lexus felt no different running on "ASDA" or Optimax
The WRX though runs like shit on anything other than Optimax, even BP Ultimate runs crap compared to the Shell, but then my car is mapped for Opti.
The newer the car, the more likely it is to be able to take advantage of it.
A common misconception is that higher octane fuel = more power which isn't the case, the calorific value governs power and it's pretty similar between normal unleaded and super unleaded.
The advantage of higher octane fuel is its knock resistance allowing you to run higher cylinder temps and/or pressures with more ignition advance so you can either up the compression ratio, increase the boost or increase ignition advance or a combination of all 3. This is where the extra power comes from.
With a normally aspirated engine, the only change you can make during normal running is ignition advance (and you could probably run a little leaner, too), but only if the ECU has reasonable knock correction (which bike ECU's don't currently have).
Any UK GSXR forums anyone can recommend, or that aren't graveyards?
This one seems busy, but the info is often so USA-biased it's as good as useless. to me.:crying:
Could really do with a UK based website that will know more about more UK-based products/suppliers/info.
Hi all, I’m trying to track down my old 1990 GSXR-750. In the UK its reg plate number is G595YNK
If the owner or anyone that knows the owner of it happens to be on here, I’d love to get in touch with them
It used to be the blue color scheme, but according to the DOT it’s now red. It’s also now...
I'm really struggling to get a quote on a new GSXR1000R in London, has anyone had success with any specialist brokers? I've tried all the usual, Carol Nash, Bikesure etc. They just don't seem to like the postcode of my garage. I have the option to store the bike at my work, 1/2 a mile...
