Long commute...

When I started using the Broquet back in 1987 David Locke said he wouldn't bother putting it through government assessment due to the extortionate cost & licences he'd have to pay for . Why do that with something you know works .. it'd be like having salt tested & licensed as a food flavour enhancer or water as a thirst quencher .

My sisters FIL .. Don Overton was a former Spitfire engine technicial engineer working in engine development in Perkins engines after WW2 till he retires in 1969 .. it was he who pointed me to the Broquet .. said all RR aircraft engines & those made under licence were using it to cope with crap fuel .

When you think about the use of E5 & E10 bio fuels & the drop in MPG you may well find it will be making a come back .


One thing Locke did say , is that no one has managed to claim his compensation award for an engine that has suffered & died because of using Broquet

Must day ive never seen this on any merlin fuel system I’ve worked on, and there’s been a few. The only “crap” about the avgas we used was it was 130 octane vs the yanks 150, allowing them to pile the boost on a bit more

I have no idea about "briquet", never having heard of it, but a thought occurs:

What, exactly, caused "spitfire fuel" to be "crap"?
Is it possible it has/had some effect on a fuel which is *much* worse quality than modern "petrol station" fuel, but negligible effect otherwise?

There was an issue with low octane fuel for aircraft but as far as I know, snake oil does not increase octane nor do anything but lighten the wallet. I would like to see the peddlers prosecuted and banned from advertising. Mike Brewer is pushing it now too, you would think that he might have had SOME integrity.

Check out the petrol used by the Russians for their Spits & Yaks in WW2

You're having a laugh.

Have you seen two identical engines that have had a similar life & run roughly the same miles stripped down , The Broquet treated fuel is as clean as a whistle in the combustion chamber & on the valves .

I can find absolutely no valid independent reference to this broquet stuff and it’s use in the merlins online. I’ve not come across mention of it in any merlin documents and I would put reasonable bets on if I asked my former boss he would not have seen any fitted either on wartime aircraft

That's because it does absolutely nothing, other than separate buyers from their money.

If you ever do even a cursory google on the subject, lots of magazines when offered free samples to trial , over multiple cars, motorbikes, they report no change (I fib - one I found reported an increase in fuel usage). Fred Bloggs of Ipswich writing in to claim he gained 3.54mpg increase, according to the ASA when D.Lock and associates were claiming miracles in their adverts:


The ASA considered that the claims were objective claims that required robust substantiation based on independent testing, and considered that press releases, customer testimonials and magazine articles were therefore not sufficient to demonstrate that the claims had been substantiated.

We considered that, in order to satisfy the claims, we would need to see evidence that the results of the tests provided would be applicable to all or most vehicles. In addition, the tests and any claims based on them should follow, or be of an equivalent standard to, those required by the EU for vehicle emissions.

We assessed the tests provided by Broquet in support of the claims. We noted that a number of the tests contained little or no explanation of methodology, and most of the tests had been carried out on only one or two cars or engines. We had not seen any evidence to demonstrate that the tests had been carried out in line with standard emissions testing, and noted some aspects of tests which suggested they had not. We also noted several other issues with the tests. For example, one test had been carried out in 1992, on a car which was manufactured in 1988 and had a 93,000 mileage. Both the car and the fuel used in the test were therefore unlikely to be representative of those currently available, and the test was unlikely to be applicable to all or most vehicles. The test cycle was also carried out using a 'hot start', which was not in line with standard emissions tests.

Given the issues we identified with the tests, we considered that the evidence was not sufficiently robust to demonstrate that the product was capable of improving fuel combustion, improving MPG, lowering emissions or making a positive contribution to the environment. We therefore concluded that the claims had not been substantiated and were misleading.

I’d sooner walk than buy anything off that fat mockney tosspot. His voice goes through me like a dentist drill and he’s got a face you’d never tire of punching

With the greatest respect, if you think it has some sort of effect, that's fine. However, like homeopathy etc, it defies all established science and has been shown to be ineffectual in tests by Practical Classics etc. They still allow it to be advertised though, so clearly money talks.

No, but I've pulled several of my engines apart after other issues, run on supermarket fuel mostly and each one has been "as clean as whistle in the combustion chamber and on the valves".

Now I've pulled older engines bought from breakers apart, thinking of Triumph Dolomite and Spitfire engines, and found all sorts of crap on the valves and pistons - I attribute that to worn out engine, worn out oil seals, in-frequent oil changes with crap oil in old cars people were running into the ground.

Modernish cars that are maintained with decent oil run nice and clean.

Naaa....everyone knows it only works if you believe in it...which is why it defies all scientific analysis because the scientists are all non believers

It brings to mind the Audiophools who have their speaker cables carried on little pylons and have power cables that cost hundreds of pounds, despite many miles of standard cabling to get the power to their houses! As you say and like religion, true believers will not be swayed by something as inconsequential as scientific fact!

A very good mate of mine used to sell magnets - strap 'em to your fuel line and gain power and amazing mpg . . . to your home gas pipe and reduce your bills . . . to your injured pet and it'll recover in no time at all . . . strap one to your wrist and cure all known ills . . .

Company selling them had to stop advertising the car claims as they were proven to be total crap on a rolling road etc.

My mate, several heart attacks, hernias, and other assorted ailments doesn't seem to be the best advert for them . . .

Admittedly, hold one under a burning cigarette lighter, and the flame does grow taller . . .

AS far as I could see, it only worked to make the man at the top of the pyramid selling scheme a lot of money from all the minions paying him a fee to see the stuff. . .

Anyway, these days, all dropping a bag of hope down your petrol filler pipe will just end up with it jammed above the anti-syphon do-dar in fresh air

So I have a brand new car, does 50mpg and is happy on E10. Will I get a 6% increase in mpg?

I preferred the transit "auto anti-rust" system that protected the engine bay on my banananana engined van.
If only they'd extended it so it constantly sprayed the entire underside with oil.

My Ford Thames was almost the same but only on the offside where it leaked from the fuel pump 'boot'. As for additives I'm afraid I only ever used R40 and the purely for the smell.

"What, exactly, caused "Spitfire fuel" to be "crap"?

The fuel during ww11 was always being up graded, have a read of the "Spitfire story" and see what problems everyone had with fuel, some of the problems the Germans had would make E10 look like the elixir of the gods it was going off in days in bulk tanks.

Depends if you put the right fuel in it and actually start the car I suppose .

Back in 1938 (or was it 37?) an American discovered a Catalyst that could be used at high temp to break down heavy oil to start the production of what became known as 100/130 Aviation Fuel, or BAM100 in RAF-speak. Prior to that everyone used 87 octane. The Germans captured a downed Spit and worked out why we had such a performance improvement but also that the DB engines in the 109 couldn't run 100/130. I wonder if this is where the Spitfire/Broquet story rose from?

Dan. Any idea what your DB605 runs on?
