Me too,  been using Valvemaster Plus the whole time as it was reasonably priced although I don't do so many miles so it is probably not  a big deal for me

I put a piece of old lead from a pipe ect in the bottom of my old mk1 S and she still runs a treat now today

I've had a quick look on the net and can't find the answer but no doubt you users will know,what's in It? as in what is the active ingredient

The Castrol is Phosphorous based.

 

The Millers is Manganese based.

Also the original FBHVC/MIRA testing of these fuel additives was carried out using A-series engines

No point using a 31mm exhaust valve, I have past the 130bhp mark using a stock 29.4mm exhaust valve. Running 35.7x 29.4mm valves ensures the maximum service life of the casting before cracking occurs. Bigger valves cracks sooner.

The valve seat inserts I use are those from minispares and are 31.75mm in diameter. You can physically seat a 31mm exhaust valve however too much heat is dumped into the casting and failure often occurs.

I looked at the tetraboost if it does indeed contain tetraethyl lead, that's a bit of a no no with road going vehicles, but there again I plan to boost octane ( not on the mini engine ) with paint thinners which no doubt isn't too correct either.

Doesnt work. You ll find next to no lead in the fuel unless you go through 1 tank a year orso

And far more caricinogenic if things like toluene are used..

Ive been using the castrol valvemaster plus in my turbo mini for the lead additive, octain booster and the fact it's in a neat bottle that you can measure how much you need.
Might have to keep the empty bottle and see if I can get the millers stuff in to it.

Yeah but I smoke so the odds are already stacked:) plus diesel is worse

Actually there is little evidence that toluene (methyl benzene) is carcinogenic. However its cousin benzene definitely is. Benzene is in much higher concentrations in 98 petrol, so if you use that, avoid breathing in the fumes whilst filling up.

 

Personally, I wouldn't use anything that contains tetra-ethyl lead. 

 

Edit: I use Morris Lubricants zero lead 2000 in my Moke. It's potassium based

+1 for being careful with TEL, this is pretty deadly stuff. But very effective.

 

The maximum permitted level of benzene in UK petrol is 1%, for all grades.

Bah - puts hairs on yr Chest

 

Fair enough if anyone in particular doesn't want to use TEL these days, but given that zillions of cars all around the world burnt it for around 50 years and now very very little burns TEL, the small amount a few older car enthusiasts are going to burn will, i feel, make little difference. Let's face it, 'life' will drive us all mad (if marriage doesn't first) and give us all cancer.

 

And yes, Diesel is WAY worse than TEL,,,,

 

I did look in to using Benzine (basically Paint Thinners) a little while ago as an Octane Booster, I'm quite sure that's what they use in the Petrol we have here in fact (that's how I steered on to it), but haven't as yet tried it.

 

In our Major Cities here, getting true higher octane fuels is usually no issue, but once you leave them - as I so often do - it can be a real headache. Further compounded to this is in some of our regional areas, where the 'Locals" (Abos) are, they can't afford or obtain Alcohol (to drink), so the often steal petrol to get 'off' on  sniffing the fumes. To 'get around' this in these areas ,they sell a 'synthetic' (pathetic?) fuel called 'Opel'. Its Octane I'm sure varies from 120 to about 50. So, it's for these reasons that I went looking,,,,,

Does anyone know the shelf life of an unopened bottle of valvemaster

[Orange-Phantom]

Unfortunately you just can't beat leaded fuel! I've ran Avgas (aviation fuel) and the olde mini just loves it. Great for racing! So next time you see that engine powered plane, remember it's running on leaded petrol.
I don't know what the Castrol shelf life is but the Millers is 2 years from the date on the bottle, I suspect it'll be similar?
