Castrol Valvemasterplus

Recommended Posts

Hi all,

since the demise of lead replacement petrol, I.ve used the above,

See its not now branded as Castrol, but classic valvemasterplus,

my question is does it have a shelf life? I have a number of unopened bottles I have had for some time,

perhaps years, its too expensive to chuck, if it still works, anybody know?

John.

Dunno for sure, but if it dissolves in petrol and there's no sludge in the bottom of the container it should work OK. IIRC it works by depositing a film of sodium on the ev seats and sodium itself wont go off. Its the organic component that makes the sodium soluble in fuel that might go off.

Im not convinced that TRs are at risk of valve seat recession, in normal road driving. Have yet to see a report on here.

John I use this millers product and it does have a shelf life I think 12months. And the bottle is dated.

Yours May be similar and may say on the bottle.

I think the Millers product contains ferrocene that may have a shelf life. Peter C. may 

be able to confirm. As for valve seat recession one of my customers covered 60,OOO mls

in a Ford Cortina ( cast iron head) before no. 4 exhaust seat suffered recession.

I checked the three bottles of valvemasterplus  I have left , no indicated shelf life or date stamp. Most other products lurking in the garage with a shelf life

have a date stamp on them either manufacture date or use by date

I feel pretty sure it should still be good to use. I only add it to every fourth fill and in the eight years I've had the car had no problems so far ( shouldn't have said that should I:ph34r: )

Harvey,  Millers VSP contains manganese as the active ingredient. its made soluble by conjugaiton with an organic molecule that is unstable, especially in light, Whic is why it is sold in black bottles.   It is toxic stuff, as the bottle states, so we are careful handling the bottle. But it is all too easy to forget wehn working on fuelling that it is in the petrol. I used it briefly to boost octane, but stopped because of the risk to the brain ('manganism resembles Parkinson's). The risk may be overstated, Canadian petrol at one time replaced lead with Mn and we havent had ( yet?) an upsurge of brain damage AFAIK.

Yep the stuff I had did. It leaves iron deposits on the plugs.

Are you sure? Manganese leaves pinkish deposits. Ferrocene oxidises during combusiton to  rust particles that are atrocious for ring/bore wear.  I doubt Millers would risk that.   Plug photos:

Hi Peter,

Yes positive if I can find the photo of the bottle I'll post it again. I'm sure I posted it a few years ago.

Darren,   Tks, didnt know that. Looks like Millers have stopped using manganese, which is wise.. On your label: the potassium compound is for protecting the ev seat, The ferrocene is an octane booster. I was very interested in octane boosters for supercharging, but ruled ferrocene out because of its effect on increasing bore wear in particular. I would not in short let ferrocene anywhere near an engine: ferrocene is like adding rust particles to the cylinders.

Why is it wise to stop using manganese Peter? I have a couple of bottles of the Redex lead substitute, which I believe to be manganese based.

Pete, Mn is a neurotoxin. Handle that neat stuff with care, and dont forget its in the  petrol so wear gloves. It will mostly come out the exhaust so dont work in a garage with engine running. That said, it is a cumulative effect so a couple of bottles handled responsibly are most unlikely to induce manganism, similar to Parkinson's. My comment was intended that globally spraying tons of Mn into our environment is not a good idea. 

But before you switch to ferrocene as an octane booster, there is emerging evidence that nanosized iron particles from brake discs and bore wear are getting into the brain of city dwellers.

To me it looks like a smoking gun, with wide potential health effects, barely yet explored. And ferrocene in the fuel will add enormous numbers of iron particulates to the exhaust. Fortunately both Mn and Fe poiosn cat converters so are banned from pump fuels in the west.

Speaking of octane, does anyone happen to know what RON was available at the pumps in '59? Curious to know what my 3A would've been inhaling originally.

"Cleveland Discol" was an ethanol-rich pump petrol ( and may have had some methanol too). What goes around comes around.... 

" National Benzole" was another high octane pump petrol with lots of benzene. Benzene is a potent carcinogen long banned. But known now to be a risk to petrol pump attendants. 

Not to mention generous doping with TEL .

But there's no reason why a TR would have needed these high octane fuels. Unless the compression had been raised.

Thanks for that Peter, interesting link to the MSM Archive article too.

So your TR may have had E25 in its tank long ago !

Deggers,  :D  Beware of professors shouting instructions from the roof . That one forgot to mention that alcohol wrecks terne-metal fuel tanks. Did TRs in that period use terne ?  Peter
