Anyone experiencing problems with the garage's supply of Super Unleaded petrol?

I've been in to a couple of my usual fill-up places over the last 3 weeks, and I usually put the super stuff in, but it's been unobtainable at the pumps.........

They still have it at Tesco near me, but if it drys up what should we do?

[Genem]

Just use the ordinary stuff. They were built to run on poor quality fuel so I suspect that, like adding "leaded" additives, money is being wasted. Save the difference for an unleaded head in 20 years time and perhaps replace the fuel lines ?

Concerned about E10, I guess. How much of the fuel supply system needs to be changed to make it safe?

Not had a problem with premium (other than the price) but the new E10 has put a massive flat spot on the power band of my 2007  Fiesta 1.25... it wasn't exactly a race car originally but the original output being so low to start with has made the loss of oomph between 2000-3000rpm all too obvious.

Worst part is because it's  "modern" I can't even tweak the mixture or timing to get it back

Chuck the new stuff in it. Mine runs well on it. A metre of fuel line is 6 quid from Halfords if needed.

I put new cheapo fuel hose in last year and running on E5 it lasted less than a year. Fortunately less than 10 mins to put a new bit of hose in. Buying from somewhere like Halfords mean you know it is going to be up to the job.

Will E10 do damage to the pump seals, electric or Lift pumps, or the seals in the carb

^^^ that's what I was wondering

E10. Sneak it into all fuel.
One way of getting rid of old cars on the road ?

Holden Vintage & Classic issued this newsletter the other day.

Am I worried ... NO

All the rubbers and seals in mine are new(ish) and rated to be used with E10.

You can also add a drop of various additives that will counter the effect of E10, prolong the "life" of the fuel (as used in garden machinery - Briggs & Stratton for example) and give the fuel an octane "boost".

The change is nothing like the loss of lead in petrol - we can manage without lead. You just need to be aware of what
rubbery parts you have in your fuel system and their age - when did you last replace them
The pipes and o-rings and other seals you buy today will withstand E10.

Happy days  :petrol_pump

Hi,

My understanding is that higher octane fuels were developed to slow down the "flame rate".

Raising the compression ratio speeded up the "flame rate", leading to "pinking" (and possibly dents in Granny Rover bonnets, due to holes burning in piston crowns, followed by dip sticks being fired out of the engines.

Increased compression ratios led to the demise of the starting handle, as Granny (the lady) was either unable to spin the engine by hand, or, kick-back would break her wrist.

Arguably, running high octatane fuel in a low compression engine will reduce  power, but it might feel smoother, due to slower burn.

Me? I'd just fill up with the expensive stuff.

Is there a typo in that document?

7. Use a non-alcohol based fuel treatment to prevent excessive water collection in your fuel. Ethanol based fuel treatments worsen problems caused by E10 gas.

Should that read “Alcohol based fuel treatments worsen problems” rather than “Ethanol based fuel treatments worsen problems”.

A small point I know but potentially an important point.

I refuelled my Land Rover at my local Jet filling station last week.
 I usually go there but hadn't filled up for a while.
Noticed that the pumps had E10 stickers on them that weren't there before.
Anyway, the Land Rover seemed to run very well after after this fill up. Better than before.

As Alan says if you have e 10 rated rubber parts should solve most problems.
Also any steel fuel,lines may be encouraged to rust. Apparently the float solder may suffer and the alloy in carbs corrode.

I did ready up and another issue is the bottom of carbs, tanks etc can accumulate acidic liquid not helping things.
Drain taps all round!
