E10 or e5

[HybridTheory]

Morning everyone.This question has been asked before im sure but I cannot seem to find the search function!

Previously I've always whacked in the cheapest fuel but now I'm not sure what one to use.according to the gov website my 2001 Yamaha can take E10 but I've also heard to the contrary

Any wisdom from anyone ?

Thanks

Need a bit more info.
What bike?
FI or carbs?
My personal rule of thumb is FI is E10 carbs get E5, but that's just me.
My CCM has a plastic tank so that's my other reason to run it on super.
All IMHO

Any 2001 Yamaha will be fine but really depends on its use, if it sits for a while then I'd be using E5, if its constantly in use, E10.

Most bikes run on E10 fine, certainly anything that new.

If you're riding regularly then E10, if you're letting it sit quite a bit then E0 (there's still plenty of places that sell it e.g. Esso Supreme in many parts of England - though not all). It's pointless using E5, it'll give the same issues as E10 but just take longer for them to appear.

Most bikes that have issues with ethanol (e.g. Triumphs and Ducatis with plastic tanks) were having issues with E5. E10 really doesn't change the long term picture much.

If using E10 the general advice is to store with the minimum of fuel in the tank or brimmed to full - this means there's either not much fuel to absorb moisture or no air gap for condensation to enter the tank (to be absorbed by the fuel).

E10 then

As has been said about 56 million times before over the last 6 months or so, carbed bikes tend to run fine on E10 but can have trouble starting in colder weather. There is a possibility on certain models it can affect the seals etc in the fuel system.

I get more MPG and no starting issues when cold on E5. If I run on E10 then it's a pita to start when below about 5 degrees.
