Your petrol of choice ??

[Dave Mann]

Ah but supermarkets do buy the cheapest that they can get away with. It's not so long ago that one supermarket chain bought some real junk fuel which damaged a lot of car engines which cost them dearly in compensation.

I bought a tankful of dodgy diesel from Tesco. The car had to be towed in to my local garage, who told me I was not alone; they had other customers with the same problem. It took Tesco three weeks to admit their fault, after Trading Standards had got involved and worked out that three Tesco filling stations all had the same problem after one tanker had delivered to them all. It seemed that the tanker driver had picked up the wrong additives at the distribution depot. It took Tesco even longer to pay after admitting their fault. If their suppliers complain about waiting too long for payment I believe them because I know first hand how Tesco behave.

Hi PeteUU

If you are still following this, I only use BP Super Unleaded, no additives. The car runs fine, no vapour lock, no corrosion, no problems starting after 6 months.

Hi Pete

I use the cheapest! .

Generally Tesco as it’s the only pay at pump supermarket for miles.

My RK was sat for over 6 months during lockdown with 1/2 tank of fuel left in.  Started on the button!

I would recommend a filter like the one Dave Mann shows earlier in the thread.

Cheers

I use whatever is to hand, always basic unleaded. Back in the day I used Cleveland Discol if I was feeling wealthy. Never had problems.
My housemaster at school always ran his Seven on paraffin when at university. Had a small separate container of petrol for starting then switched over to paraffin. Only modification was to take the pipe to the carb twice round the exhaust downpipe to preheat it a bit.

I have used Tescos finest Super Unleaded for a long time now.
I do not do many miles nowadays but drive the car hard when I do.
My engine is almost set up as a full race engine in a road car using up to 7000 Rpm on the road and running a lot of advance at high revs.
It is the practical choice for me cost is not a factor for me.
Unleaded petrol has a lower density which mean float level adjustment might be needed.
My motorboat flexible fuel line rotted out after using E5 fuel. The type of fuel line usually goes hard as it ages in my case it just disintergrated.
Now replaced with ethanol resistant fuel line.

So it is E10 day 1 Sept 2021. The government has launched a search facility at https://www.gov.uk/check-vehicle-e10-petrol where you can search your make of vehicle to see if it is compatible with E10. IT doesn't even list AUSTIN! You have to ....................Quote from site

"My manufacturer is not listed
Not all manufacturers publish E10 fuel compatibility. This includes many classic manufactures, companies which are no longer trading and more specialist brands.

If you're not sure if you can use E10 in your vehicle, you could:

check the vehicle owner's manual, the instructional booklet is specific to your vehicle
look inside of the fuel filler flap
ask the car, motorcycle or scooter manufacturer / local dealer
If you're still not sure, use E5 petrol. It will still be available in the super grade at many filling stations." End of quote.

Being tighter than a submarine's window I've been using E10 in the RP for a while without any problems.

Although our Sevens appear to run well on almost anything, you can get Esso Synergy Supreme+ 99 Octane which is currently E0 - but costs much more. However, ethanol is about a third less energy dense than pure petrol and, in the US, the Environmental Protection Agency says there's between a three and four per cent reduction in fuel economy using E10 compared with pure oil-based petrol. In 2014 "What Car?" magazine conducted a series of tests of compatible cars running E10 bioethanol fuel against running on pure petrol. All four cars suffered a reduction in fuel economy ranging from six to 11.5 per cent, with the larger-engined cars suffering the least." So, this looks like a lose-lose for everyone as those filling up with E10 will have to spend an additional 6 to 11% to travel the same distance as before. Seems crazy to turn food into fuel....

[Dave Mann]

Ah but our government thinks E10 will reduce the CO2 emissions!
