E10 fuel additives

[Flat 6]

Hey all,

I see Wynns now offer an additive to overcome the effects of E10 on older motors. Anyone got a view on how effective that is likely to be?

I run the SC on super but also run two other 70's classics which really don't warrant super...

Cheers,

Al.

The Wynns product seems to treat more fuel than equivalent products.
They claim 250ml one shot ( at around £12 ) will treat 250L and is costing you 4.8p per litre.
Millers EPS equivalent ( at around £10.50 ) claim 250ml treats only 50 litres so is costing over 20p a litre.

I stopped using the Millers treatment when I realised it was cheaper to fill up with Esso Synergy 99+.

I would be surprised if the Wynns product was terribly effective at a 1:1000 dilution, but maybe they have come up with something 5x better than the Millers product.

I suspect their definition of 'protection' is different to other manufacturers.

Either way you will never really know with any of the additives, but will know for sure if you source fuel without ethanol for the time being.

I can't see why the fuel companies don't add an ethanol protector as standard - there must be a reason.

The Millers VPSe raises the octane number by two points - it’s more than just a ‘substitute’.
Only Esso does ‘ethanol-free’ fuel but unfortunately it is not available in Devon or Cornwall due to ‘distribution problems’…

I did compare it to Millers EPS which is just a protector and not an octane booster according to Millers - so is a like for like.

VPSe is a different product that does have an octane booster (have used that also in the past).

Not wishing to highjack the topic, but it’s an associated question. Do we have any thoughts on what to do over winter when vehicle usage is lower and the likelihood of water separation is higher, or at least the effects are more likely to be felt? I guess run the tank down to a low level is easiest. I use Millers additive but am not sure what this does over the longer term, say not using the car for a couple of months.

It is relevant imho.
For 30 years I've never bothered where the tank is, empty to full ish.
I will have the car stored again but will have the tank quite low due to storage company request, but will use Esso ethanol free. as already in the car at some level.

[Ian Comerford]

Thank you, maybe just switching to Esso ethanol free is the simplest.

Porsche make an additive for adding to the tank of a car in long term storage, they also make a claim that their Classic Oil is suitable for long periods between firing up the engine. We’ll see ! I’m using both this past year.

The thing with all these potions is you will never know if they work.
If the tank is already rusty from exposure to ethanol then the potion will not fix that, or the pump seals, or the hoses etc etc.

If the parts are virgin new then I would expect them to work, but only after a long time will you now, usually when there is a failure.

Just using ethanol free fuel seems the solution if you can get it.
E10 with the potion is a good step if you are in an area that is starved of 'E0' but it will not repair damage already done.
