Thoughts on the new E10 petrol?

[randroff]

My 2019 Audi A5 mileage and possibly performance has gone down with E10. Is anyone else feeling the same? What is the ideal fuel nowadays?

[Shytot]

I've not noticed anything obvious yet on my Q5. 

My journies have been fairly consistent and I've filled up twice with E10. 

I typically get a range of 500 miles when full and on this one it's sitting at 40% / 199 miles 

I've not noticed any performance issues so far. 

How does it affect your performance?

My advice would be to put in premium as that's still e5.

Thanks, Shytot and Steve. As a test, I filled up shell v-power yesterday and did some local and motorway drive. It could be placebo, but the car definitely felt responsive (especially gears 2 to 4) and the mileage shown in the short-term memory is over 7mpg more than last value. (28 vs 35).

That's a significant difference. 

I'm getting between 7 and 8 miles per litre. 

I can't see the premium petrol giving me enough additional range to justify the 29p per litre price difference. 

Looks like you just need to monitor and go with what suits you 👍

Try Octane booster it definitely works.

I hadn't thought about it but my last 3 Refills have been at Shell and Tesco Express / Esso, as opposed to Morrisons - maybe the supermarkets are more susceptible at present?
