I could give you a bag of rusty nails for half the price and I guarantee it will be equally effective and could even last 200k miles!

Yes but nails are not made from tin amalgam or covered by product liability insurance underwritten at Lloyds . So, again,has any one used additives like this and do they work? I know the liquid gear works but this stuff seems a one off treatment. I will probably get the valve seats done eventually but this stop gap might do.

I would imagine that would be a complete nonsense. Why don't you just throw some money away?

Hi
Has anybody suffered from valve seat recession since the introduction of unleaded petrol?

The simple fact is that one will never understand how beneficial any of these products are, unless you compare the results to an identical vehicle that didn't have the product fitted and both vehicles are subject to identical driving loads and distances !

These products that claim to be simple to use but cure all ills ; in this case, low octane, poor lubrication, stops petrol going stale, works with all fuel types, stops knocking! Have to be viewed with some scepticism......this is the same company that sells a device that puts a break in an ignition lead, and markets it's as an ignition booster!

If the Hillman Hunter had an aluminium head, recession wouldn't be much of a problem, because the head would already have hard inserts.

The same goes for old aircraft engines, they would probably have had Stellite inserts.

Lastly leaded petrol was introduced in the twenties not the thirties. 1922 I think. It was a result of a collaboration between General Motors and Standard Oil Company

Have just had to rebuild my spare engine as the runner threw a big end.

Also found the block has a couple of hairline cracks on the top of the block.

(You got any e93a blocks left Rick)

I digress

As to valves,
I stopped using the additives after advice from an old chap, in his 80's, who has been in the trade, and still runs his garage.
He said they are just a money spinner, also said "there wasn't a problem with them before they started adding lead and anyway they would be work hardened by now.

There is NO sign of recession with my tuned e93a, and it gets used regular and hard, be doing about 400 miles this weekend, and it runs with the rest on Motorways if I need to but try to keep off them.

So I have found additives are a waste of money but I only use Super.

I fitted a similar gadget, but in the fuel line, to the Morris 8 in 1996, when leaded fuel was withdrawn in NZ. At that stage we were pretty much in the dark about the possible consequences. It wasn't expensive and I worked on the basis that even if it did no good it would do no harm. It's still there, hidden away just above the front of the tank, but in the intervening years I've used several different engines for relatively low mileages, so I really can't say whether it's had any effect on valve seat recession. The current engine's done about 9,000 miles since complete overhaul.

A lot of old car men in this country believe that unleaded fuel goes 'stale' if left unused for more than two months, but I've never had a problem despite the car being off the road for lengthy periods from time to time, in one case for ten months. Whether this is down to the Fuelstar gadget is anyone's guess. I'd think the process of going 'stale' is either a case of the aromatic octane-boosting additives evaporating or heavier elements of the fuel separating and sinking to the bottom of the tank, where the line picks up the fuel; but, as I say, I've never had a moment's trouble from fuel being past its use-by date. Indeed, the thought has never crossed my mind.

According to the blurb published at the time such devices came onto the market, they were first used for the Hawker Hurricanes sent to Russia during the war, Russian aviation fuel being too poor for the R-R Merlin engines, which would knock severely even under moderate boost pressure. Despite a life-long interest in wartime aeroplanes I'd not heard that tale before and have not seen any reliable source to verify it.

This story has done the rounds for years,its a load of tosh,I supply tools to various aircraft museums all over the world and all of them reckon the story is nonsense.
The thing you buy on ebay that you put in the tank is basically a couple of lumps of lead in a bit of wire mesh,it is complete and utter nonsense. You might as well get a couple of air gun pellets and stick them in your tank,the only thing they'll do is stir up the dirt and eventually wear a hole in it.
Ebay is the last refuge for this snake oil rubbish,no reputable car magazine or publication carries adverts for them anymore and no scientific journal,motoring magazine or trading standards type body etc has EVER found they have any beneficial effect at all.In fact a few of them have had run ins with trading standards in the past for misleading claims.
I can supply you for £20 with a genuine money saving device. Its recyclable,fits any car,saves a fortune on fuel and increases economy and reduces engine wear. Its a block of wood to go under the accelerator pedal and I bet if I stuck it on ebay someone would buy it.

HL Mencken wrote this in the twenties:

No one in this world, so far as I know - and I have searched the records for years, and employed agents to help me - has ever lost money by underestimating the intelligence of the great masses of the plain people.

He wrote the scripts of some of the Marx Brothers films and was a philosopher disliked by others of the same ilk because he became very rich.
