Both CS Speed and CHF are ATFs, but of a much, much higher quality than a Liqui Moly TopTec 1200 for example, with CS Speed being somewhere in between ATF and CHF.
In certain Selespeed systems Agip CHF is also the factory fill, at twice the cost per litre of Tutela CS Speed. But anything stating compatibility with Pentosin CHF 11S will do and is miscible with both synthetic ATF and CS Speed.
Will you notice any difference between TopTec 1200 and CHF 11S anywhere outside of Siberia? Probably not, but at 10 quid per litre at Halfords, the CHF is very well worth it.
