ESSO had dropped my consumption to 18mpg... Asda junk saw it leap in the correct direction...

60 litres of BP 95 (that oddly smelt like real petrol - with all the associated health benefits of leukemia etc.) and a long run of 400 miles saw my journey average jump up to 28.7 mpg yesterday

more Facts some want to pretend are irrelevant - FYI quite a lot of your engine is made of aluminum.... first I knew of this was decades ago where speedway engines destruct from the filth

ethanol is corrosive in a fuel tank made of metal, because it contains soluble chloride ions... Corrosion will damage metals, including fuel tanks, fuel system components made of plastic and rubber, injectors, and emerging deposits. In 2001, several models of vehicles that used alcohol fuels in Japan reportedly experienced fuel leaks and fires due to corrosion in fuel system components made of aluminum. Then, an investigation by a team to prove the case, used an immersion test on metals and other materials used for the fuel system part to determine the corrosion resistance of ethanol contained in the fuel. The results of this study indicated that a high concentration of ethanol causes corrosion in the fuel system components made of aluminum

The +/- 10mpg difference between Esso and BP fuel can only be down to the traffic conditions at the time of using both brands.
I'm more than sceptical that a change of brand will result in a 10mpg difference in economy.

no doubt the different road conditions made a big difference - but the point of the rant was both my main used car and bike are drinking ESSO fuel like there is a hole in the tank since the change to higher levels of ethanol that massive step change came directly after getting best result I'd ever had using ESSO,

on local runs I got 5mpg uplift adding asda trash under the same driving conditions... and with 60% of the tank full of BP E10, 30% Asda E10 and 20% ESSO E0% I was shocked that it got 28.5mpg - nearly the best I've ever seen and allegedly mostly all E10 rubbish - which would indicate ESSO have created magic nothing and the others aren't as bad

The strange thing was the stink of the BP from that forecourt was like real petrol - but two other BP garages I've been trying on the BIKE smell of nothing and the bike its struggling to run

its not all octane numbers either

post introduction of high ethanol garbage fuels sept last year

From ESSO E5 95 (where I had seen 29mpg on long runs and mostly 25mpg round town)
I started with Shell E10 it was dropping MPG big time,
Tried ESSO E10 it was worse (diving from 25mpg round town to 17mpg and seemingly in a death spiral)
Tried ESSO E0 99 it gained a bit, increasing to 19mpg
Added 50 50 Adsa E10 and ESSO 99 E0 and got to 22mpg round town instantly increasing from 17 to 19 mpg
Now mostly BP E10 seems to be doing 23mpg round town


on the bike I had come to the conclusion tanker drivers and unscrupulous forecourts are pumping the good stuff in certain tanks they always fill from - the car on the BP and then the bike on BP doing the exact opposite - would seem to suggest that's happening too - and to be honest why wouldn't they !!!

speaking to a bod filling a shell garage from his tanker today - he's forgotten which way round it is....

devon and wales getting ethanol filth all the way makes sense...
fawley make the ethanol filth on site so infect all local supplies...
everyone else train's in the rubbish so can add if they want...
reading gets its fuel from theale (???) so they wouldn't have it by default and need to add it so u can have a choice - hence felt shell 99 could be ethanol free too

Ethanol does not contain chloride ions unless contaminated.
Ethanol has the chemical formula C2H6 - no chlorine at all - just carbon and hydrogen.

I will keep saying this and have had several other members confirm from their long term observations that using E10 for years has not caused any issues.

Debating with a conspiracy theorist is pointless. They just conclude that you are part of the conspiracy.
