Why close Cosworth Topics?

[Jason8691]

I have noticed that most of the topics opened about Cosworth oil get closed shortly after they are posted, why is this?

i believe it is because there are a few current topics already available about this oil. also if you go down a few threads there is a thread about cosworth oil and it has some links in there.
