OK, quick update on the little ethanol-reduction experiment.
Bit of background: old bike I've put back on the road myself, with bespoke fuel system with slide carb plus ported cylinder head, and ignition timing changes. Not set up for fuel economy - just a leisure machine for short, fun rides. Fuel mileage isn't great and isn't bad - tends to depend on how rough vs smooth I am with the throttle. It will break traction in loose gravel or mud in a controlled way if you lean forward and mash on the throttle a bit, and that's all part of the fun. That sort of stuff seems to bring down mpg, but you can also ride smoothly and it will just sip fuel. A couple of months ago I speculated on BCF that, with a manual fuel tap, it should be possible to reduce ethanol content with a simple move or two. This bike, I decided some time ago, will only get E5 fuel. I'm not saying it wouldn't be fine with E10 or that others don't get OK results with E10. It's just a decision I made, and which I will stick with because it's not worth thinking about. A couple of days ago, I had to fill it up with E10. I rode it a short distance home, then brimmed the tank by adding water, then agitated it vigorously.
I left it standing in the garage, relatively upright. Just now, leaving the bike where it had been standing, I disconnected the fuel hose and drained away about 1.5 litres, into a fuel container. The stuff smells oily, but you can tell, it isn't petrol. It looks like water and it behaves like water. The 5l petrol container into which I drained it smelled of old petrol slightly. But the stuff that came out of the tank was mostly water. I kept putting my finger in the path of the draining fluid. It smelled distinct, until at one point it seemed to smell more volatile, like actual petrol. Not exactly scientific, I know. I kept going a little while, and turned off the fuel tap. Going by the fuel can capax, I'd say about 1.5 litres was drained away.
I turned off the tap, reconnected the fuel hose, turned the tap back on (to RES) again, and drained the single carb. I waited a few seconds to let the carb bowl fill before starting the bike. Starting the bike, it started first time. I was surprised, because I suspected I hadn't drained enough from the bottom. I left it idling for about 5 minutes. I revved it up to 3k rpm several times. It seemed absolutely fine. Actually sounded healthier and better than normal, unless it was just my imagination... Absolutely dead steady.
The long and short of it is, I did what I'd been planning to do in the event I had no choice but to fill with E10. I am under no illusions that I have drained ALL the water and eth from the tank. The res pipe is short but will not catch all of the dregs from the bottom of the tank. I cannot rule out that the bike has always had the same quality of fuel, but I always get it from the same petrol station and same grade (E5 Tesco). Anyway, not very exciting, but that's it. |

Why not just use premium fuel? Shell V power and the like. Once you have played around with water and draining it off you've probably wasted more that the difference in price between premium and E10.
If you are doing it for fun and experimentation then fine. Fill your boots. (but not with the water you drain off. ) ____________________ Triumph Trophy Launch Edition |

You could add food colouring to the water, then you'll see the separation point much clearer when draining the ethanol solution from the bottom.
Not essential for your experiment, but be aware that taking the ethanol out reduces the octane rating of the remaining fuel, and you may be washing out other water soluble fuel additives, such as octane boosters and detergents.
If you were using it in a forced induction or high compression ratio engine, you would get better results by adding more octane booster to the depleted fuel. Xylene and toluene are relatively cheap unbranded versions, and are well known octane boosters in the turbo tuning scene.
This extra cost, unknown quality outcome, and time taken, is why most will stick with E10, or fork out extra for E5 super, which is still 'up to' 5% ethanol by the major distributors. ____________________

Accidentally rated you "funny" when I was trying to rate you "helpful". Sorry about that. I've just rated another post of yours "helpful" to make up for it. |

I got my ex to take the battery off, although I could have done it myself.
He just happened along at the right time, after delivering my new mirror.
Not put it on Optimate yet, cos I are still got no distilled water.
My fridge's resident ice-monster doesn't have cauliflower cheese OR chips in it (kitten-killing carbs )
But it's helpful to know that one could use that (if one had to).
Thank you ____________________ Not nearly as interesting in real life. |

A bit more Triumph tinkering today. As well as the wiring on the previous one progressing nicely a new one (as in old with bits missing) has turned up. No carbs so weighing up whether it should have the original Amals or just lob on some Keihin knockoffs just to get it running ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

Pootled down to Maidstone in the sunshine yesterday, inappropriately dressed as usual: light jacket, jeans, summer scarf and gloves. (but proper boots)
Pootled home today, a nicer ride than I was expecting, given that it was grey and cloudy looking, but luckily there was still some sun left in the Sunday, and I didn't freeze (went thru the Dartford Crossing, just in case, though )
Every time I go out now, I think "this will be the last of the decent weather, last sunny day ride til next year" ... and it turns out not to be.
I think the run of good luck on that front is about to stop
Snarley's booked in for an MOT on Tuesday.
Might get a couple more good-but-cold weekends out of it, if I'm lucky.
Note to self: time for some proper winter gloves, luv. ____________________ Not nearly as interesting in real life. |

Inspecting and greasing head bearings on the div. The steering had started to feel quite loose and sloppy, wanted to inspect before just replacing.

All cleaned up to go back in.

Felt a lot better with lots of fresh grease and nipping up tight again.
Managed to pickup a second hand Jama twin silencer system to replace my internally rotted silencer.

I had a very helpful conversation at the mechanicky bike shop.
I nearly need a new back tyre, but not quite. Unsurprising really, considering I've owned it about six years and have never put new boots on it at all yet.
And a forkseal looks like it might be starting to go, so he's going to nip that in the bud.
The skanky old drive belt that needs replacing is also being gouged by some sharp pointy thing holding the oil tank on (he thinks it might be the pointy corner of a cable tie but its too grungy to tell for certain), but he is going to have a look at that when he changes the belt I already bought. Which may or may not need a new sprocket.
And he will have a look at the oil leak on the left, and replace the sidestand spring. I'm unconvinced about the sidestand spring, but I will let him do whatevs, and see if that makes a difference.
So he is gonna order me some parts and call me when he's got them in. My plan is to pester him every two weeks until he has
Meantime ... I have a new clutch and a new MOT and am ready to menace traffic afresh, hoorah! ____________________ Not nearly as interesting in real life. |
