Yeah apparently my 03 Golf GTI is one of the cars on the list that won't run on this new E10 stuff.

Think it's gonna effect a few makes/models of cars that were manufactured 2000 onwards i believe, i did see a list but can't remember off the top of my head what other cars were on it, just noticed that my Golf was classed as one that won't run on this new bloody stuff allegedly, but like you say another way to get rid of older cars same as dirty diesels.

Doubt E10 will add any power: They'll use it as a blend with even lower octane basestock.
In other words 95Ron will still be 95Ron. (and remember minimum LEGAL standard of super is 97Ron...regardless of what octane it says on the pump). But you will use more of it as it's a oxygenate and will make the oxygen sensors throw off the fuel trims and enrich the mixture when running closed loop. And it's overall calorific value is lower (you need more of it to produce the same amount of energy).

My bigger concern is if it throws off the oxygen sensor ageing adaption (VAG thing; It actively monitors oxygen sensor response ) and catalyst efficiency monitoring.
With that in mind, if anyone has OBD live data monitoring, it's worthwhile monitoring the fuel trims before switching over.

Had a fella come over and had a chat at a Shell the other week. He has a 1 year old Golf R and it run poor on E10.

running poor on e10 95 octane or should have been run on sul 99 e5 , shell 99 or momentum both are fine for the scooby , i think the general consensus from a similar post our cars will be fine , but as we know they should be run on higher octane not 95 , i was told by my engine tuner avoid bp sul as not as good as shell or tesco 99 👍

super only , ideally not bp sul , so only use tesco 99 or shell 99 , or you risk engine damage , an octane booster only adds a bit more octane , so if you did a 95 and put octane booster in it’s still not enough octane to run safely on , all jdm scoobies that i have had , so 5 cars or so now , have been fine with out a re map on shell or tesco 99 octane

Lavorg GT on E10?
I'm interested to see how the E10 effects my daily , which is a 2017 Lavorg GT , the gov website says it will run fine but in reality who knows , I'm probably going to fill up in a day or two so fingers crossed I don't notice a difference , .
my 2003 STI I'm not worried about that has always had 99ron .

Racing fuel like E85 which is 85% ethanol (not 10) and is over 105+Ron.
Forecourt petrol already uses octane boosters to get the base fuel to its 95/99Ron rating. What they will do is substitute that octane booster for more ethanol. Or blend it with octane lower base fuel theyby octane will be the same.
Petroleum is made by blending all sorts from the various stages of refining crude oil. The high octane component derived from crude are usually Alkylates. And it's this component that naturally gives it a higher octane; Blend more lower octane components in like Naphtha and the octane decreases. The target octane is what's on the label at pump. So for E10 95Ron to still remain 95Ron, they are going to use less Alkylates and probably blend in more Naphtha.
As an aside Naphtha makes great easy-start if you ever have a reluctant lawnmower or chainsaw (usually found in plumbing pushfit connector lubricant and WD40)
