So essentially a 17 bit variable always equates to that series of numbers?  That would be just about the limit of my understanding 🤕!

Neil Watterson has a recommendation for Millers Power Ecomax in the latest LRO. Not an in depth study, just his observations.

[Wittsend]

This type of product/additive is totally different to the Gloop scam which started this topic.

Millers Power Ecomax is a diesel fuel cetane improver - it works 
It does a similar job to the +diesel premium fuel as sold by Shell & BP
You get more "bang" per litre - you have to decide if the cost justifies itself.
I use a similar product off eBay, 5 litres works out much cheaper than Millers.
I put a cupful of the stuff into every tank fill.


This is what I use and I recommend diesel owners at least give it a try.

(I also put a squirt of mineral based 2-stroke oil in the tank every so often along with an egg cup of acetone.)
I use this to do the squirting 
I expect Millers (and others) have a similar octane booster for what's known as "petrol".

These are proven products and without a proper analysis of this "gloop" we have no idea if it is in the class as the Millers product.
Bearing in mind the negative effect ethanol has on performance.

 :thudI don't use any additives. Fortunately the 2.5 petrol engine is factory fitted with an unleaded head and I run it on super unleaded as I don't trust the E10 rubbish. Going on mileage between brimming the tank the fuel consumption appears to have improved by about 10% but I certainly wouldn't be able to guarantee it 100%. I certainly wouldn't use some magic gloop like RunGreen at £67 for 50 ml. I suspect using super unleaded is cheaper than standard unleaded with "octane boosters."

Whilst were on the subject, anyone tried this ? Again advertised in CCW.
No Smoke Oil.

[Wittsend]

Would this be some sort of synthetic oil

Synthetic oils are not really suitable for old Land Rover type engines - best stick with good old mineral oil and keep the engine well maintained and rebuild after 70,000 miles or so.
If your engine is smoking (heavily) after it's warmed up then something is wrong - it's knackered.

I have had to reduce picture size to fit but I will have a read through and see what it says in that regard.

[Alan Drover]

I've looked at their website and there are no properly conducted tests to prove the claims. I can't find a price either but it ain't gonna be cheap. Don't be conned by it. All these magic gloops are certainly coming out of the woodwork.
The distribution centre is in Northamptonshire. It appears to be "formulated" in the EU.
No magic gloop will cure a knackered engine or improve emissions/fuel consumption.

Yes, almost. A 17 bit variable is limited to that range using that particular format. Other formats are available such as unsigned binary which would have a range of 0 to 131071 and binary coded decimal which would have a range of 0 to 19999. Then there is floating point representation that can be processed by more advanced microprocessors such as those in your PC, where what you can represent is a trade off between magnitude and precision, i.e. you could represent a very large number but at the expense of not being able to represent the lower order digits.

Thanks for this reply!   Certainly a world of magic and alchemy!!

I recall a book from the 1960's - "The Dawn of Magic".  If I remember correctly it was describing the end of the certainty of the Newtonian perspectives of the universe we inhabit. 

I will get my coat..........

I use the same stuff as Wittsend in all 3 of our diesel vehicles, it is certainly cheaper than premium diesel which is 30p per litre more expensive than standard diesel at our local fuel station

Hi,

If you buy petrol already containing an additive, are you paying fuel duty on the additive, plus VAT on the total.

If you buy the additive separately, you are only paying VAT.

That is a good point 602 .
I had a look online for 'Stop Smoke Oil', it is £50 for 4 litres, couldn't see if it synthetic or not. It has good reviews on Amazon 
It requires an engine flush first and appears to be a standard oil additive pre-mixed with the required engine oil.
I did use some Wyness stop smoke on my Dads Fiesta Diesel, worked enough to get it through the MoT but not for long.

Does the "increase" in performance/mpg warrant the cost?

[Alan Drover]

I posted the comment but however hard I try I can't get it as a separate entry from the quote.
I am a renowned computer idiot though so please excuse me.
