E10 fuel by September 2021

[nv76]

Hello all.

I just tried reading the whole thread but I found slightly difficult figuring our what is the conclusion to this thread. I will attempt to summarise it and do shout if I got anything wrong:

1. For BMZ Z3, regardless the year of manufacturing, it is better to use E5 97+ for any kind of use (dairy or not).
2. It may not be easy to find E5 97+ in Tesco Express and small gas outlets but bigger outlets will have it.

1. Is anyone aware of an internet map that potentially shows gas outlets and what type of petrol is available? Or did I just give out an idea for a app for free?
2. On the gov site, it states: "Petrol stations that offer 2 grades of petrol will stock E10 (95 octane) and E5 (97+ octane) petrol. "

3. It is not advisable to leave the same petrol in the tank for long periods as this will result in issues with the engine or starting up.

1. Could you explain what do we mean when we say long periods? Is one month a long period or not? Approximately should be fine.
2. Could you elaborate what you mean when you say engine issues?
3. Could you elaborate what you mean when you say the car might not start?

Please do let me know if I have missed something

Here in America we have been using primarily e10 for years, I don’t even remember how long. It seems to work fine, I use it in my z3, and 1985 carbureted Jeep cj7 without any obvious problems. I’ve heard it can eat through rubber lines and varnish your carb and all sorts of bad juju, but I don’t let things sit forever so I haven’t experienced anything like that. I think that’s just urban legend... You could drain the tank or use a fuel stabilizer if it were going to sit for months and months guess. Best to take it out for a spin once in a while

Yesterday I had to go to 3 petrol stations before I could find any 97+, the first 2 forecourts were “pumps not in use”. So any economy saving was used up in the extra 10 miles I drove, not to mention Shell V Power was £1.55/litre !

Think I will bite the bullet and switch to E10.

If E10 has less actual petrol in it the tax should be less? or am i being too simplistic

Nice idea Paul, but I doubt it would fly mate.

Go for it Paul, unfortunately its a fuel tax rather than petrol tax - doesnt say what the fuels made up of

I don't actually think in practise that we will notice much difference between the E5 we have now and E10. It's only when you get to sort of E85 level that issues like water vapour absorption, poor cold starting and plastics/synthetic rubber degradation become really significant. In other words there might have been a bit of media hype going on (who would have thought!)

When I worked in a laboratory, I used to run my old cars on all sorts of mixtures. My favourite was 5% acetone, 5% isopropanol and 90% petrol. The car used to run really smooth and go like hell, but it was a b****er if you got it on the paint as it stripped it immediately. Toluene was a favourite with the plant operators, but since Toluene is a bonded spirit, the customs and excise people once came to site and sampled the workers fuel tanks, so that put paid to the (tax free) fun. They found two with high levels of Toluene, one using red diesel and one with some paraffin in. Oh, how we laughed.
