E10

#1 Post by andrewstretch » Tue Sep 07, 2021 9:52 am

Hi guys,
As we all know the fuel at the pumps has changed for some not a problem for others a classic car owners nightmare.
I but £20 worth in a nearly empty tank to see how my 2000 1.8 45 of 75.800 miles would fair, well i have to say i did notice under heavy acceleration an underlying knock, i also have to say the £20 did not last very long, i am retired so do not drive everyday so the car sits on the drive most of the time. And the £20 lasted 3 weeks, normally would be around 4 weeks.
I then put £20 of E5 , and the response and performance was a lot better, but sadly again not many miles for my buck. Although my findings are slight and maybe unnoticeable to some, it is a concern.
So it seems my old 45 will suffer when they take the E5 fuel off the courts, as we rely on a car both myself & mom having health issues we need some thing reliable and fuel efficient.
So as diesel has not changed... i think it's time to change cars sadly.
Has anyone else noticed a difference..?

Andy.

I think I read that the calorific value is lower somewhere, there is another thread running about this.

I have not used E10 in my 220 turbo coupe, using e5 super unleaded c. 32 mph, using Esso 99 c. 37 mpg (nb gear ratios appear to be the shorter 620ti box 3200 revs @70mph), however read something that this is because latter is E0 still, but only in the Midlands. Used to use Millers vspe power plus additive with another car a couple of years ago (same model, the red one...) with similar results e0 vs e5 (i.e. a 5mpg drop from upper to mid 30s, with a longer ratio gearbox 2500 revs@70), but not tried again recently. On a mix of roads with mix of right-foot behaviour.. :D
[caveat: red coupe had dizzy but new one has wasted spark which might make a difference]

https://www.esso.co.uk/en-gb/fuels/petrol.
Although our pumps have E5 labels on them, our Synergy Supreme+ 99 is actually ethanol free (except, due to technical supply reasons, in Devon, Cornwall, North Wales, North England and Scotland). Legislation requires us to place these E5 labels on pumps that dispense unleaded petrol with ‘up to 5% ethanol’, including those that contain no ethanol, which is why we display them on our Synergy Supreme+ 99 pumps.

There’s currently no requirement for renewable fuel, like ethanol, to be present in super unleaded petrol although this could change in the future, in which case we would comply with any new legislation.

Some very interesting info here about about E10 fuel and availability of E5 - https://fbhvc.co.uk/fuels#E10

On a personal note I've been using E10 in my vi for most of the last half-dozen fills and I've been surprised by the fuel consumption - in a good way :-)

I've been getting over 40mpg, and up to 43 once. It's not a scientific analysis, as I've done a couple of longer (for me) journeys in there, but the highest I've had while using the car for 2 years was high 30s. I will continue to monitor :)
I like Twin Cams.... and Single Cams

I've been using E10 since the start in my VVC Coupe.

Iv'e not run to an empty tank yet to properly see and calculate the MPG, but I think its increased, based on how far the guage is going down, per miles done.

also, there is certainly no drop in performance, misfires, or any thing else negative with the running of the car

I did reset the Fuel Adaptations with T4 so the ECU can learn its parameters from scratch again. Worth doing.

That's interesting. Does E10 contain the same cleaning agents as in Shell VPower/BP Ultimate? I wonder how much it improves emissions at MOT time?

My gut feeling from filling my D16 once with E10 was that the consumption had dropped, I've only used Super unleaded ever since, seems to pull better at low rev's too.

Some fuel companies suggest that their super has more detergent in it but that's a separate issue.

There is some discussion about ethanol absorbing moisture either from the atmosphere or the air in the tank when it's left standing. Look on UTube for separating ethanol from petrol, the process involves adding water to fuel and then draining it off!
