Hi all,
Ever since the demise of leaded fuel, I've been using Superblend Zero Lead 2000 because it passed all the Federations tests by miles and was the leading contender.
Some time ago, I bought several bottles of the stuff and as I'm now on my last bottle, started hunting for a supplier. It seems that the Superblend company no longer exists (not that I could find anyway) but the product is now called "Superclean Zero Lead 2005" and produced by Morris Lubricants. I think that Morris Lubricants made the original and licensed it to Superblend, but could be wrong.
Anyway, I phoned Morris and it seems that they have changed the receipe slightly to change the colour and some unwanted nasty chemicals - but they did say that it would not affect the job it was supposed to do. Hmm I'm not sure I'm swayed by that as it's now not the product that was tested by the FBHVC, and I'm thinking of moving to one of the other products. So, a couple of questions.
1. Castrol Valvemaster seems to be the most prolific - as it's sold in Halfords. Any comments on this one?
2. Anyone got a link to / copy of the Practical Classics article on the results of the FBHVC testing so that I can remind myself.
3. I'd like to know the wisdom of safely changing from one additive to another. Superblend is based on Potassium, and none of the other additives are.
Thanks for your help,
Brian.
