Best brand of petrol?

[RichS1000XR]

Not wanting to turn this into a "what oil" style of thread, I've noticed that my bike runs smoother depending on what brand of petrol it put in it.

Since fitting the full system, I always go for premium/ super unleaded, and the bike will run smoother or rougher, depending on which brand of petrol I've used.

I filled the bike up with BP super the other day, and surprisingly it doesn't run as smooth as it does with Shell.

Has anyone here noticed the same? What's your go to brand of choice?

Shell V Nitro turbo you cant bend it, or whatever its called.  Only cos its the highest RON from the nearest garage.

Shell V-Power for me too as it's 99 RON.

Strangely enough just had the same conversation with my other half on the way home and I prefer BP Petrol or Diesel for the bikes/van/car and have the choice of either BP or Shell within half a mile of the house.

While in NI last week getting 97 or 98 was a pain cuz not everyone sells it and a lot of Italy is the same.

Just a quickie from a tanker driver all the fuel is basically the same ie Asda Tesco Morrisons Esso Shell the only difference is the additives that each company puts in and obviously the big fuel companies  Shell Texaco Esso Bp use a better standard of additive. All the superstores fuel comes from the big companies terminals anyway so it's the same product but super fuel ie 97 octane will run and be better for your bike, you should notice a slight increase in mileage as well. Just a quick heads up for everyone though if your near a Costco they are starting to spring some garages up, their fuel will be very good quality being supplied by texaco/valero and they will be using their own high quality additve and it's cheaper too so happy biking everyone 👍👍👍

You guys are lucky out here in California U.S The best I can buy is 91 Octane, California also requires a special blend of gasoline only used by us to reduce air pollution thats bad on engine performance .

At one point in the past couple years BMW had recommended Shell high test for all their race motors due to the additives.  Wish we could get 97 octane over here without all the ethanol added.

Hey some years ago I raced a Yamaha RD400/ 430 Drag bike we used C16 race fuel to keep the tops of the pistons cool.  "Motor Octane of 114 if memory serves"
Not cheep but dam sure is fun stuff!  To be fair you could maybe get a way with running C14 or C12 the only down side it they have Lead in them in so maybe not for everyday use
