I agree with every thing you are saying PH – BUT I still say the individual oil change sets are a rip-off.
Stupidly I bought 2 * 25ml sets (wish I had bought the 1 litre now). I got ripped off - and I know it - hence the comments above.
N.B. you will note that I still think the Speedhub works out cheaper in the end.
