Morris Minor Owners Club

Hi,
Has anyone purchased or tried this intank lead replacement rather than the liquid addatives. If they do the job it would pay for itself pretty quickly.

Just search this forum for terms like "valvemaster" or "catalyst". For starters, try this topic:

You'll find everything you need to know.

The short answer is - it's a complete waste of time and money..... The good news is - you don't need any additives unless you intend to drive your car hard on the Mway for long distances. [Moderated]

Spend the £25 on wine, woman and song.
Unless you thrash your Minor on the motorway for hours on end you won't have a problem.
Even if you do, tin amalgam won't help your valves.

Wine it is then!!!!!!!!!!!!!!!!

Waste of money to put anything metal in the tank and hope that it will somehow dissolve in hydrocarbons and protect your valve seats.

By the way, I am not criticising any person, product or company, merely passing on scientific information!

I used to work as an industrial chemist and I can assure you that there is no way that lead or any other metal pellets in the tank will do anything at all! (except rattle around!)

Fortunately there is no guesswork or mystical motions needed - the Classic car clubs and industry funded some serious testing on lead replacement additives (Using A-series engines driven through an equivalent of 50,000 miles). Valvemaster was one of the products that was PROVEN to work - doing nothing was proven to cause serious VSR.
Some products failed the testing, and some suppliers refused to submit a sample of their product (make of that an easy conclusion).

VSR takes a lot of miles and comes on quicker if you drive hard and/or high revs. A good additive is one of the options - an alternative is to wait until there are valve problems (hopefully never) and then do something about the head.
Cost wise depending on how many years you want to keep the car and how many miles per year the sums become a bit more clear.

Using an unproven additive is also an option, but is hard to justify compared to the readily available ones that work - equally adding an unleaded head on a car that does a few hundred easy miles per year and hasn't got damaged valves is not the optimum cost solution.

By the way, it is still possible to buy leaded four star, if you can find it

And if that is not available it is still possible and perfectly legal to buy the very best additive- Lead tetraethyl ; http://tetraboost.com/

Now that WILL protect your valve seats and increase octane. BTW, I have no connection whatsoever with this company.

I can get leaded fuel near Leamington, but additives work out much less expensive.
